Report
taken from Bulletin
3/99 :
We had the honour to organise and host the annual
SGSMP continuous professional education course in
Bellinzona. The subject chosen for this year, Electronic
Portal Imaging Devices, their physics and the practical
application in clinical routine, revealed to be appealing
for our Society. More than 70 participants attended the
meeting, including roughly 15 collegues from Northern
Italy. As a second great result, we have to underline and
recognise, the enthusiastic cooperation from the
companies invited to sponsor and to
participate to the meeting with their contributions.
Bioscan (from Geneva), Elekta, Infimed, Siemens, Varian
and Wellhoefer accepted our invitation and guaranteed the
presence of technical speakers at the meeting. The
generous sponsorship of one company allowed us also to
invite Dr. M. van Herk from the Netherland Cancer
Institute. He’s one of the pioneers of the field and
was invited to report his deep experience about a
particularly stimulating application of EPIDs: clinical
in vivo dosimetry using a liquid ionisation EPID. The
second invited contribution which enriched the program
was coming from the Paul Scherrer Institute; Dr. Eros
Pedroni presented their prototype of a dosimetry
verification system for scanned proton beams using a CCD
camera, a promising way to extend EPID technology to more
exotic applications. Thank you Eros for your friendly
participation.
From the companies we obtained an equilibrated mixture
between the technical aspects of their products and the
commercial information. To summarise the future of EPIDs
in a couple of statements, we firstly learnt that
dosimetric applications will guide research and
developements and secondly that new (silicon) detectors
will allow significative enhancement in resolution and
contrast with shortest acquisition times and better
calibration control. Also in the field of Quality
Assurance, the tecnology of Electronic Portal Imaging
will finally help us for routine controls of beam
characteristics, even for dynamic beams (like dynamic
wedges). Some of the EPIDs are already equipped with
dedicated tools, and on the market we can now find other
dedicated instruments which seem to offer versatile
devices, machine independent, for two dimensional QA
procedures.
