Description
The Crystal Clear Collaboration has built a positron emission tomograph (PET), the
ClearPET and is now working on a dedicated PET for mammography, the ClearPEM.
The aim of the ClearPEM is to be able to depict small tumors with a diameter of 1
to 2 mm in the breast and axilla region.
The ClearPEM consists of two parallel plates (17.3 x 15.5 cm2) with 96 detector
modules. Each module consists of a 4x8 crystal matrix of 2 x 2 x 20 mm3 LYSO
crystals, optically isolated from each other and coupled to 32-pixel avalanche
photo diodes (APD).
According to the simulation data the read out electronics should be able to cope
with 12288 channels with a double event rate of 1MHz over a background of a 10MHz
single event rate.
Since a PET device images the metabolism the structural information of the body has
to be obtained with a different technique, such as ultrasonography.
In this work we investigate the compatibility of two different systems of automated
3D ultrasound probes with the ClearPEM, regarding geometrical constraints, the need
of compression plates, sound transmission between the body and the transducer.
