Patent number: 10281594Abstract: 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.Type: GrantFiled: May 3, 2018Date of Patent: May 7, 2019Assignees: Consejo Superior de Investigaciones Cientificas, Universitat Politécnica de ValénciaInventors: José María Benlloch Baviera, Filomeno Sánchez Martínez, Antonio Javier González Martínez

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
