Improvement studies of Compton cameras over gamma cameras in nuclear medicine treatments

The use of Compton cameras (CCs) for imaging radioisotopes in nuclear medicine can offer benefits over conventional gamma cameras in some aspects, for example in assessment and dosimetry of treatments with radionuclides, in which photon emission is not optimized for gamma camera performance. The IRIS group of IFIC (Valencia) has developed a CC MACACO III, made of LaBr3 crystals coupled to silicon photomultiplier arrays and is evaluating it for nuclear medicine, in different treatments in which its use can be advantageous over gamma cameras. In collaboration with the nuclear medicine department of La Fe Hospital in Valencia, data were taken with phantoms and patients with
