Krakow
the European City of
Culture for 2000, is one of the most visited cities in Poland. This former capital
city has a wealth of preserved buildings and culture over many centuries. It is
a major centre of science and learning, its renowned Jagellonian University is
one of the oldest in Europe from 1466. The University Museum contains many
items dating back to Copernicus, who received his degree there. The main square is the largest medieval
market square in Europe. In the centre is the famous Cloth Hall from the 12th
century, which today is a centre for local arts, crafts and souvenirs. A few
hundred meters away stands the Royal Castle commanding a view of the whole
city. The origins of this historic building date back to the year 1000 AD.
The Conference Centre is a pleasant building
in the old town district belonging to the Polish Military. It has art deco
styling typical of the early 20th Century, with a conference hall and
exhibition area on the first floor.
Campanile Hotel is conveniently located a few minutes walk
away and is less than 5 minutes walk to the old city square, with its abundance
of restaurants etc.
Krakow Airport Balice is near the city, and
can be reached by bus and taxi. Good International connections include Chicago,
London, Paris, and Rome. Regular daily flights link to Warsaw’s International
Airport.

About the Conference
Since 1977 a successful series of
Symposia has been organised by our Society every year. At the beginning these
events were named “Symposium on Thermogrammetry” after a newly developed branch
of thermal mapping methods which played a significant role in the program. As
the scope of the symposia widened in 1982 they received the new name “Symposium
on thermo-technical measurements”.
Due to the broad and increasing
interest shown by the international thermal engineering and physician
communities, in 1987 it was already organised as the International Conference
on Thermal Engineering and Thermogrammetry (THERMO). This conference is a
series of biennial meetings. The Conference is intended to be an event worthy
of the attention of all engineers, scientists, physicians and researchers who
are involved in the solution of thermal or energy related problems, as well as
in the applications of thermal imaging.
Objectives
The developments of measurement
theory and technologies help the energy- conscious design of thermal
engineering equipment and processes as well as the better understanding of
thermal phenomena in living organisms.
The Conference will cover topics
both the field of theory and application including new measurement concepts;
transducer technique; thermal mapping; contact, optical and IR imaging;
biomedical and biotechnological applications; thermal informatics, automatic
methods and systems for industrial energy management and process control; heat
loss detection and analysis; heat and mass transfer; utilization of alternative
energy; thermophysical properties as well as the common practice of thermal
engineering.
This Conference will provide the
latest information on the above topics together with a good opportunity for personal discussions
among experts in the fields of energy conservation, control of energy release
and loss, protection
of human environment, medical and veterinary applications, remote control through infrared
sensors.
Main Topics
The structure of the sessions will
be fixed after receiving the papers, but the topics will cover the following
fields:
General thermal engineering; theory of measure- ments; thermal informatics,
thermo-CAD and its applications; industrial energy management and process
control systems; practice of thermal engineering; infra-red imaging science & technology: thermogrammetry, micro- and nano-
scale thermal phenomena and sensing techniques, thermal defectometry; applied thermo- optics; thermophysical
properties; heat and mass transfer; cooling of electronic components; heat exchangers;
combustion; thermophysics of the environment; building services; environmental
aspects of energy use; thermo-ergonomy and thermo-psychology; thermo
diagnostics; system analysis in thermo-biology; IR-imaging in biomedical and
bio-engineering applications;
remote sensing through IR-imaging, multidisciplinary topics.

Detecting Breast Cancer with A New
Algorithm and a Multi-spectral Infra-Red Imaging System
(Press Release,
Office of Naval Research, 800 N. Quincy St., Arlington, VA 22217-5660 http://www.onr.navy.mil/ )
What does remote sensing for
camouflaged enemy ground vehicles have to do with breast cancer diagnosis? By next
year, perhaps plenty. A smart sensor fusion algorithm modeled on the human
visual/brain “unsupervised“ learning System and a 200 channel hyperspectral
remote sensing capability have been developed by the Office of Naval Research
for use as a passive electro-optical, infra-red ground surveillance system. The
same method has now shown success in detecting the heat radiated by abnormally
reproducing breast cancer cells.
Hyperspectral sensors sweep up enormous quantities of data, but their
usefulness has been liniited by our ability to pull the important information
out of that clutter. The algorithm that processes the data is the important
factor. Last year the Under Secretary of Defense for Science and Technology
asked ONR to look at the potential usage of remote sensing to improve breast
cancer diagnosis. Dr. Harold Szu and Mr. James Buss‘ single-pixel unsupervised classi-
fication algorithm, based on the Lagrange Constraint Neural Network (LCNN) and multiple
spectral data per pixel initially designed to increase the effectiveness of
surveillance systems, now promises to enhance the sensitivity and accuracy of
breast cancer testing.
Abnormally reproducing cells demand
greater nutrition through increased blood supply, thus generating higher concentrations of heat in
specific areas. Applying their algorithm, Dr. Harold Szu and Mr. James Buss are
able to classify the infrared heat distribution given off by these cells.
A truly unsupervised algorithm per
pixel must be based on the information derived directly form spectral data
alone. In order to reveal the hidden spectral features contained in a single pixel image data vector
X=[Ä]S, one has to invert the matrix without knowing both the
breast-medium heat-transfer matrix (MTF) [A] and the heat source 5 which both
vary from pixel to pixel. While ONR‘s spave-variant imaging algorithm following
the spectral data vector analysis and the physics constraints of thermodynamics
free energy minimization has achieved sub-pixel accuracy, other statistical Independent Component
Analyses (ICA) methodologies suffer pixel-averaging blurring effect.
This is because the average over neigh- borhood pixels must imphcitly assume an
identical MTF [A] for the space-invariant imaging. This would be true only in
cases of a large tumor requiring no more automatic target detection.
Similar to a pair of human eyes, a
pair of cameras at different infrared
wavelengths —wavelength IR (3-5 jtm) camera and Long wave- length IR (8-12 ~tm)
camera. Both have about 10 milli Kelvin degrees in the minimum resolvable
temperature difference (MRTD) — transcribes this thermal diffusion process into
two images, which are then filtered for shared signals while disagreement noise
is minimized. Through this process, last February Szu and Buss and their team
detected early stage ductal carcinoma in situ (DCIS) in a test patient using a
double-blind procedure (see images here:
http://www.onr.navv.mil/ops/media/download.htm)
“This multispectral, sub-pixel
super-resolution is potentially more accurate by an order of magnitude,“ states
Dr. Szu, “lt offers a passive, inexpensive, non-intrusive, convenient means of
screening pre-cancer patients without radiation hazard, and may potentially
detect in situ carcinomas long before a mammogram might detect them.“
Thermal breast scanning
has been employed for a number of years, especially in Europe and Asia, but its
use has been limited to a single infra-red band, using a single camera. The
application of the
“unsupervised“ classification algo- rithm may offer an unbiased, more
sensitive, accurate, and generally more effective way to frack the development
of breast cancer, without demanding the variables of a long wait in a cold
room, increasing the variability inaccuracy in thermal detection and causing
patient discomfort.
The success of the
initial double-blind experiment substantiates the promising application for the
use of multispectral imaging in improving the early detection process for
breast cancer and possibly other dermal carcinomas. A provisional patent
application has been filed. Follow-on research and clinical studies are being
planned through the use of Cooperative Research and Development Agreements (CRADA).
A web-based database of medical images (MedATR) is being
developed by Advanced Concepts Analysis Inc., of Falls Church, VA, hosted on
the Air Force Virtual Distributed Laboratory secure web site (VDL).

“Medical Infrared Thermography” meeting report from the Royal Free Hospital
This year’s UK Medical Infrared Thermography meeting on 18th
May attracted some of the leading experts in the field of thermal imaging. Speakers
came from across the UK, and also from Austria, Germany, the Czech Republic and
the USA.
Prof. Francis Ring (University of Glamorgan
School of Computing) gave the opening keynote address on the history of medical
thermo- graphy. He
described how Sir William Herschel’s discovery of infrared radiation in
1800, and Carl Wunderlich’s groundbreaking thesis on medical thermometry in
1871, were the initial steps towards thermography performed with today’s
state-of-the-art focal plane array thermal imagers.
Dr. Graham Machin (National Physical
Laboratory, Teddington) gave the inaugural Brian Chu Memorial Presentation.
Brian worked on temperature standards at NPL for 19 years, and was developing a
blackbody calibration source for medical thermography at NPL prior to his untimely death in April
2002. Graham described the importance of regular calibration of medical
thermal imagers, and the challenge of demonstrating that temperature
measurements are traceable
to the International Temperature Scale of 1990 (ITS-90).
Dr.Paul Campbell
(Ninewells Hospital, Dundee) spoke about the use of thermography in surgery, which
is being pioneered by Prof. Sir Alfred Cuschieri in the Department of Surgery
and Molecular Oncology at Ninewells. Paul presented some thermographic observations
of a heat-activated shape memory alloy suture staple. He explained how
thermography has helped in the optimisation of the staple design by visualising
the heat flow through the alloy when it is heated resistively to achieve
closure. Paul next explained
how dynamic thermo- graphy is also used at Ninewells to determine the
degree of thermal spread from surgical instruments in energised surgery. This
work will be important in optimising energised surgical techniques to ensure
that there is minimal collateral thermal damage during such procedures.
Prof. James Levine (The Mayo Clinic, MN,
USA) gave an informative and highly entertaining presentation of his research
into the detection of deception using thermography of the face. This work was
first published in Nature at the end of last year, and attracted a great deal
of media interest on both sides of the Atlantic. Jim explained how the ability
to reliably detect deceit would be of obvious benefit to national security, but pointed out
that deception and harmful intent are not the same thing. He then
presented his group’s findings, which show that warming of the area around the
eyes is an indicator of deceit comparable in reliability to a US Department of
Defense polygraph test. The potential benefit of thermography over the
polygraph is that infrared imaging could in be employed in principle without
the subject’s knowledge.
Kevin Howell (Royal Free Hospital,
London) closed the meeting by thanking the participants and sponsors, and
presenting a brief review of the state of medical infrared thermography world wide. He
explained that the next European infrared thermography meeting was due to take
place in Krakow in June 2003. Plans were also being made to publish the
proceedings of the London meeting on CD ROM this summer, and establish a
database of UK researchers with expertise in medical thermo- graphy. Kevin also
brought a number of resources for thermographers to the audience’s attention.
The UK Thermography Association (UKTA) Medical Section is the national
organisation promoting medical infrared imaging, and publishes a regular newsletter. “Thermo-
logy International” is the journal of medical infrared imaging, published by Prof. Kurt Ammer
at the Ludig Boltzmann Institute in Vienna. A searchable archive of
thermography papers in .pdf format is available for purchase from Prof. Ring at
the University of Glamorgan.
The meeting was supported by the
Engineering and Physical Sciences Research Council Grant GR/S00026/01, and
sponsored by Flir Systems and Moor Instruments.
“Thermology International” for UKTA Medical
Section members
“Thermology International” is the Embase- listed journal of
medical thermography. It is the official scientific journal of the UKTA Medical
Section, and a large number of other national and international medical
thermographic associations world-wide. UKTA Medical Section members can
subscribe to “Thermology International” at a discounted rate.
The UKTA committee is keen to
encourage increased uptake of the journal. To further this aim we have reached
a new agreement with the editor, Prof. Ammer, which means UKTA will distribute
the journal to members in the UK and collect subscriptions.
To subscribe to “Thermology
International” please complete the form enclosed and send a cheque for £30 to Kevin
Howell at the Rheuma- tology Department, Royal Free Hospital, Pond
Street, London. NW3 2QG. Cheques should be made payable to “UKTA”. The fee is
the sterling equivalent of the 32 Euro subscription fee, plus a charge for
banking and mailing fees. Henceforth, copies of the journal will be forwarded
to UK subscribers by Kevin Howell at the Royal Free Hospital.
UK members of the “Thermology International” editorial board will continue to
receive copies of the journal direct from Vienna.
If you have any questions about
this new arrangement, please contact Kevin Howell by e-mail at infrared_thermography@
hotmail.com
Becoming a “Medical Section” member
A number of general
members of UKTA have expressed an interest in joining the Medical Section, and
have asked if it is necessary to pay the subscription fee quoted on our Medical
Section subscription form in addition to the general membership fee. In fact, any full UKTA member can join the Medical Section at no
additional cost. Just let Kevin Howell know, and he will be pleased to add you
to the “Medical Section” membership list. This will give you the right to receive the
dedicated medical news- letter, and to subscribe at the reduced rate to
“Thermology International.”
The Medical Section
subscription rate exists solely for medical users of thermography who do not require full
general membership of UKTA or use of its services to industry. Consequently,
these “Medical Section only” members have reduced UKTA membership privileges.
New Member Profile
The UKTA Medical Section
is very pleased to welcome Dr. Paul Campbell as our latest member. Below is his
profile, which will also appear in the forthcoming database of medical thermo- graphic expertise to be
issued on CD-ROM along
with the proceedings of the London meeting. If you attended the London
meeting, or are actively involved in medical infrared thermography in the UK,
Paul needs your profile for the database (in a format similar to his profile
below) right now! Please send all copy to Paul’s address at Ninewells Hospital.
We intend to include profiles of both new and established Medical Section members in future
newsletters, so any profiles submitted will fill a dual purpose, and will be
most gratefully received by the editor!

BACKGROUND
Paul is a graduate of London
University (BSc Physics 1990) and Queen’s University Belfast (PhD Experimental
Physics 1994). He gained research experience in the field of infrared modelling
whilst a Higher Scientific Officer with the Defence Research Agency at Farn-
borough, and has held experimentally based postdoctoral positions at the
Universities of Bath and Belfast. He moved to his present position as Senior
Research Fellow with the Surgical Technology Group at Dundee in May 2000. In
the past year he has conducted a major thermographic study in collaboration
with the renowned
keyhole surgeon, Sir Alfred Cuschieri, to assess the use of infrared
imaging as an adjunct to energised surgery. Dr Campbell has held grants from The
Nuffield Foundation, EPSRC, The Royal Society, DTI, and The Well-
come Trust in the past. He was the
co-organiser of the ‘UK Symposium on Medical Thermal Imaging and Related
Techniques’ which took place at the Royal Free Hospital earlier in the summer.
APPLICATION: Thermography during energised surgery
KEYWORDS: Dynamic thermography; cancer; energy
based
surgery; endoscopy; computational modelling;
thermal collateral damage; black body
calibration sources; thermal physics
Energised surgical
instruments are commonplace and may rely on ultrasonic; RF bipolar (and
monopolar); or laser based energy sources for operative purposes. A typical
surgical goal might
be to seal or dissect vessel/tissues quickly, and such energised
approaches usually work by heating the target structure into a distinct
temperature regime to achieve an alteration in the physical properties of
tissue. Under such circumstances, it is usually found that tissue outside the
target region of interest is also affected by the heating procedure, leading to
collateral damage. We have begun an extensive study of collateral damage and
mechanisms whereby it can be reduced or indeed eliminated during energised
surgery. Monitoring instrument activation using thermal imaging has proved to be a powerful adjunct to
surgery and allows: power levels to be optimised in situ, as well as
facilitating observation of relevant clinical parameters such as the level of
blood perfusion and also the direct assessment of seal integrity. We will
enhance our activity in this area in the near future through the development of

Thermography for the
assessment of osteoarthritis
For the first time since years a
short paper was published in the Annals of Rheumatic Diseases discussing the
advantages of thermal images in joint disorders. A group from Japan (1) reported a correlation between
surface temperature over the knee joint with narrowing of the joint space of
the tibiofemoral joints. The authors found also a correlation between the level
of temperature and the size of osteophytes. Some significant correlations between temperature and clinical symptoms were
also reported, although the correlation coefficients were less than 0.7
in all comparisons, being best with a figure of -0.65 in the comparison of knee flexion
and temperature. An astonishing relationship between knee temperature and the
ability of walking was described, which showed higher temperatures on the
medial and especially on the lateral tibiofemoral joint in patients without
restrictions in walking than in subjects with impaired walking ability.
The authors tried to control
for inter-individual variations of skin temperature by subtracting the mean
temperature of the patella from the temperature of the medial or lateral knee
respectively. The findings of this study showed higher temperatures over the
lateral than over the medial part of the knee. Engel (2) described in healthy
subjects higher temperatures at the medial part of the knee.
Japanese subjects with- out any
impairment in standing or walking presented with two or three-fold
temperatures at the lateral knee than at the medial knee. Differences in body
structures found in Japanese and in Europeans might contribute to these
different thermographic findings.
