A PET imaging device for observing a brain includes a hollow three-dimensional structure with a shape capable of housing a head. The PET imaging device comprising multiple independent gamma ray detection modules that together form a structure capable of surrounding the head, said detection modules comprise continuous scintillation crystal blocks, wherein 'continuous' means that the crystal blocks can be continuous in one or in two directions, each of the continuous scintillation crystal blocks has a polygonal main cross-section, and said structure is an elongated structure having a major axis in a direction corresponding to the front-nape direction and a shorter axis in a direction corresponding to a straight line joining ears on the head. The continuous scintillation crystal blocks are positioned adjacent to fit laterally in an exact manner with each other throughout their entire thickness, building a mosaic, without gaps between adjacent crystal blocks and without overlapping each other.

A read network topology for a matrix output device with a number of outputs determined by cross-joining 'm' rows and 'n' columns comprises a basic filtering block replicated for all the outputs and separately assigned to each of the outputs; each filtering block contains two filtering circuits that have a common input connection to the assigned matrix output and that provide two separate symmetrical and filtered outputs; all the row outputs (i) from the same row &#x201c;i&#x201d; but from different columns are interconnected to an input of an amplifier linked to row &#x201c;i&#x201d;, and all the column outputs (j) from the same column &#x201c;j&#x201d; but from different rows are connected together to an input of an amplifier linked to column &#x201c;j&#x201d;, the complete topology appearing when &#x201c;i&#x201d; and &#x201c;j&#x201d; are expanded in the respective intervals thereof.

The invention relates to a PET imaging device for observing the brain, characterised by comprising a structure with a shape that is capable of accommodating a human head, having independent gamma-ray detection modules, said detection modules having continuous scintillation crystals with a polygonal main section, wherein all together the detection modules form a hollow three-dimensional structure that can surround the head, and with said three-dimensional structure being elongated and having a main axis in the direction corresponding to the forehead-nape direction and a shorter axis in the direction corresponding to the straight line joining the ears, and with the adjacent scintillation crystals fitting together laterally in a precise manner along their entire thickness, forming a mosaic-like structure, i.e. without leaving gaps and without overlapping with one another.

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.
