摘要: 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.

摘要: The invention relates to a hybrid medical PET-SPECT/MR imaging device comprising at least one scintillating crystal and at least one module for detecting radiation which contains at least one matrix of photodetectors and an electronics section, such that said module has a mechanical structure, the external, internal or both surfaces of which are divided into at least two sections, of which at least one is coated in graphene, and the rest in non-ferromagnetic conductive material, or all the sections are coated in graphene, and such that the coating forms a Faraday cage. The invention also relates to a shielding against radiofrequency for a medical imaging device, comprising a graphene coating, which is continuous or in bands, on all the faces of the mechanical structure of the detection module of the device, or a graphene coating, continuous or in bands, on at least one face, combined with a coating of non-ferromagnetic conductive materials on the remaining faces, and said shielding forming a Faraday cage.

摘要: This disclosure describes an imaging radiation detection module with novel configuration of the scintillator sensor allowing for simultaneous optimization of the two key parameters: detection efficiency and spatial resolution, that typically cannot be achieved. The disclosed device is also improving response uniformity across the whole detector module, and especially in the edge regions. This is achieved by constructing the scintillation modules as hybrid structures with continuous (also referred to as monolithic) scintillator plate(s) and pixellated scintillator array(s) that are optically coupled to each other and to the photodetector. There are two basic embodiments of the novel hybrid structure: (1) the monolithic scintillator plate is at the entrance for the incoming radiation, preferably gamma rays, and the pixellated array placed behind the plate, all in optical contact with the photodetector, (2) the order of the scintillator components is reversed with the pixellated scintillation plate placed in front of the monolithic plate.

摘要: The present invention refers to a method to reduce the number of signals to be read out in a detector characterized in that it comprises using a lower photosensor granularity at least at the center obtaining a granularity degree at the photosensor that is edge dependent, wherein the granularity at the detector corners can be higher than at any other detector zone or wherein the granularity at the detector edges can be higher than at any other detector zone, and wherein the number of signals to be read out is reduced by joining signals in at least the center zone of the detector, or is reduced by using different photosensor elements at the center of the photosensor with regard to the remaining photosensor zones, and its use in nuclear medicine imaging techniques.

摘要: 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 “i” but from different columns are interconnected to an input of an amplifier linked to row “i”, and all the column outputs (j) from the same column “j” but from different rows are connected together to an input of an amplifier linked to column “j”, the complete topology appearing when “i” and “j” are expanded in the respective intervals thereof.
