Description
The TOPEM project was funded by INFN with the aim of study the design of a TOF-PET system
dedicated to prostate imaging.
During last year a big effort was put into building the prototype of the endo-rectal probe
from all point of view: mechanical, thermal, electrical.
A dedicated integrated circuit was adopted to have the minimum dimensions: the TOFPET Asic.
The system is composed by a LYSO pixellated crystal is seen by a 128 SiPM matrix on both surfaces:
this permits Depth Of Interaction (DOI) measurement.
The 4 needed ASIC are handled by a FPGA board which transmit the acquired data over an UDP connection.
The external container was made using 3-D printing technology: internal channels on the external
surface permit the flowing of controlled temperature (˜ 35 ºC) water.
Electronic components power is dissipated using an internal air flow kept at lower temperature (˜ 20 ºC).
The probe is MR compatible: a dedicated small antenna can be accommodated in the container.
This will permit simultaneous imaging in MRI and PET systems.
