One of the most successful fall-outs of the research in HEP is the
application to Medical Physics. This regards the use or the adaptation
of instruments conceived for particle physics, as well as the extension
to the medical field of software techniques in data retrieval and analysis.
CALMA is a good example of the latter application: this project is aimed
at the archiving of a large quantity of clinical records related to
mammographical examinations, at the realization of stand-alone acquisition
and analysis work-stations, and at the construction of a fully automated
image-analysis software for diagnostic purposes.
In all of these aspects of the project, now half way to completion, the
techniques developed for HEP and for other research fields like astronomy
have been widely exploited. In particular, the image-analysis tools
heavily rely on the use of feature extraction packages and of Neural
The experience gained by the collaboration in dealing with data for trigger
and analysis purposes in HEP has been extremely beneficial.
The talk will give a brief overview of the underlying clinical problem, and
will concentrate on the specific software tools realized ad-hoc or adapted
from existing packages. A preliminary evaluation of the performances of the
sofware will also be reported.
