A gamma ray Compton TOF camera system includes multiple detector modules, each comprising a gamma radiation sensitive material and arranged in layers formed by one or more detector modules. The layers are placed such that they interfere an incoming gamma ray in order to completely or partially absorb it after one or more Compton interactions and are spatially separated in order to allow for the determination of the temporal order of each gamma ray interaction inside the camera system. The camera system also includes read out electronics and a Data Acquisition System where signals from the detector modules will be readout, digitized and sent to a processing unit, which is capable to obtain the 3D position, energy and temporal sequential order of the individual interactions produced by a single incident gamma ray.

The subject matter of the invention is a method and an electronic circuit for reading the signals generated by one or more pixelated sensors in a gamma radiation detection system, which makes it possible to substantially reduce the number of electronic channels to be digitized. The electronic circuit in the invention is analog and can also be coupled to other similar circuits in order to acquire the signals from larger sensors.

The GAMMA/RF compact, hybrid and integrated system for PET-SPECT/MR simultaneous imaging of the invention comprises a GAMMA/RF device that integrates an RF coil, of the type used in conventional MR systems, with GAMMA radiation detector modules of the type used in PET or SPECT systems, so that combined PET or SPECT and MR images are obtained.

Gamma ray detector characterised in that its structural elements are a continuous scintillator crystal, a position sensitive photodetector and associated electronics intended to calculate, in addition to the gamma ray energy in the position of its interaction in the crystal, the interaction depth in the crystal from the standard deviation of the scintillation light distribution. Said information may be obtained electronically, in analog form and therefore instantaneous, from the first three moments of the scintillation light distribution. A method for implementing said electronics by way of a network of resistances characterised for analog and simultaneous computation of the first and second distribution moments is also disclosed.
