Patent number: 11918403Abstract: System and method are disclosed for imaging acquisition from sparse partial scans of distributed wide angle. During real time image reconstruction, artificial intelligence (AI) determines if there is enough information to perform diagnostics based on initial scans. If there is enough information from the fractional scans, then data acquisition stops; if more information is needed, then system performs another round of wide-angle sparse scans in a new location progressively until a result is satisfactory. The system reduces X-ray dose on a patient and performs quicker X-ray scan at multiple pulsed source-in-motion tomosynthesis imaging system. The method and system also significantly reduce the amount of time required to display high quality three-dimensional tomosynthesis images.Type: GrantFiled: December 10, 2021Date of Patent: March 5, 2024Assignee: AlxSCAN, Inc.Inventors: Jianqiang Liu, Manat Maolinbay, Chwen-yuan Ku, Linbo Yang

Patent number: 11885041Abstract: The present disclosure provides a method for increasing luminescence uniformity and reducing afterglow of a Ce-doped gadolinium-aluminum-gallium garnet structure scintillation crystal, a crystal material and a detector. Sc ions are doped into the crystal material, and the Sc ions occupy at least an octahedral site. The effective segregation coefficient of active Ce ions is increased by a radius compensation effect of Sc—Ce ions and adjustment of lattice parameters, thereby the luminescence uniformity of the crystal is increased and the energy resolution is optimized; and at the same time, the potential barrier for Gd ions entering the octahedral site is increased, thereby the probability of the Gd ions entering the octahedral site is reduced, the density of point defects in the crystal is decreased, and the afterglow intensity is reduced. A general formula of the Ce-doped gadolinium-aluminum-gallium garnet structure scintillation crystal is {Gd1-x-y-pScxCeyMep}3[Al1-q]5O12, 0<x?0.1, 0<y<0.02, 0?p?0.Type: GrantFiled: May 27, 2021Date of Patent: January 30, 2024Assignee: CHINA ELECTRONICS TECHNOLOGY GROUP CORPORATION NO. 26 RESEARCH INSTITUTEInventors: Yuchong Ding, Jingjing Qu, Qiang Wang, Lu Wang
