The IRIS group at IFIC is testing a Compton camera for the visualization of the radiopharmaceutical in the patients body in targeted radionuclide therapy (TRT) assessment.
The prototye, MACACO III, is composed of three LaBr3 monolithic scintillator crystals coupled to SiPMs arrays, and it employs the ASIC VATA64HDR16 driven by the AliVATA data acquisition board for the readout. To enhance the system's efficiency an enlarged second detector configuration has also been developed by combining four crystals per plane.
Initial successful tests were conducted in collaboration with La Fe Hospital (Valencia) to image phantoms filled with FDG and 131I-NaI, as well as thyroid cancer patients. Within the ICOR project (ASFAE/2022/019) the evaluation of the system has now been extended to include alpha emitters. Simulation studies have indicated the potential for imaging Ac-225 and a measurement campaign has been carried out at the Léon Bérard Centre (Lyon). Preliminary images of a phantom filled with Ac-225 have been obtained.
