Patent number: 10838084Abstract: 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.Type: GrantFiled: June 28, 2018Date of Patent: November 17, 2020Assignees: General Equipment for Medical Imaging, S.A., Universitat Politècnica de Valencia, Consejo Superior de Investigaciones Cientificas, Bruker Switzerland AGInventors: Liczandro Hernández Hernández, Antonio Javier González Martínez, Albert Aguilar Talens, José María Benlloch Baviera, Noriel Pavón Hernández

Patent number: 10228471Abstract: 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 pixelated scintillator array(s) that are optically coupled to each other and to the photodetector.Type: GrantFiled: May 4, 2017Date of Patent: March 12, 2019Assignees: General Equipment for Medical Imaging S.A., West Virginia University, Consejo Superior de Investigaciones Cientificas (CSIC), Universitat Politecnica de Valencia, Bruker BioSpin AGInventors: Jose Maria Benlloch Baviera, Antonio Javier Gonzalez Martinez, Stan Majewski

Patent number: 10197651Abstract: 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.Type: GrantFiled: June 29, 2017Date of Patent: February 5, 2019Assignees: General Equipment for Medical Imaging S.A., Consejo Superior de Investigaciones Cientificas (CSIC), Universitat Politecnica de Valencia, Bruker BioSpin AGInventors: Juan Pablo Rigla Perez, Antonio Javier Gonzalez Martinez, Jose Maria Benlloch Baviera

Patent number: 9915739Abstract: An apparatus to detect gamma rays, comprising a scintillator, a position sensitive photo sensor and a scintillation-light-incidence-angle-constraining, SLIAC, element, the scintillator has faces and the position sensitive photo sensor detects scintillation photons exiting a scintillation photons transparent face of the scintillator, and a portion of a scintillator face is covered with an absorbing layer, which absorbs scintillation photons created by scintillation events due to the interaction of incoming gamma rays with the scintillator, and the SLIAC element is optically coupled between a scintillation photons transparent face of the scintillator and the position sensitive photo sensor and the SLIAC element guides the scintillation photons exiting the scintillator towards the position sensitive photo sensor, and the SLIAC element restricts the maximum allowed half light acceptance angle for the scintillation light hitting the position sensitive photo sensor to less than 45°.Type: GrantFiled: December 19, 2013Date of Patent: March 13, 2018Assignees: General Equipment for Medical Imaging S.A.
