Patent number: 11779293Abstract: A system and method for the prediction of a thermal load for a proposed imaging procedure in view of the current thermal state for an imaging system employs a suitable software program/algorithm which determines a predicted or likely set of individual steps for a proposed imaging procedure to be performed. The system receives parameters for the particular imaging procedure to be performed and compares these parameters with information stored concerning prior performed imaging procedures to locate prior performed imaging procedures that have similar parameters to that for the proposed imaging procedure. The system utilizes the similar prior performed procedures as models of a likely set of imaging steps for the proposed procedure and estimates the heat generation produced by the models. The software program/algorithm can then determine if the entire proposed imaging procedure represented by the models can be successfully performed under the current thermal state for the imaging system.Type: GrantFiled: October 29, 2021Date of Patent: October 10, 2023Assignee: GE Precision Healthcare LLCInventors: Thomas McCarthy, Lionel Desponds

Patent number: 11771387Abstract: An X-ray imaging system using multiple pulsed X-ray sources in motion to perform high efficient and ultrafast 3D radiography is presented. There are multiple pulsed X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Each individual X-ray source can also move rapidly around its static position in a small distance. When an X-ray source has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source stay momentarily standstill. It results in much reduced source travel distance for each X-ray source. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.Type: GrantFiled: January 14, 2021Date of Patent: October 3, 2023Assignee: AIXSCAN Inc.Inventors: Jianqiang Liu, Linbo Yang, Manat Maolinbay, Xiaohui Tang, Chwen-yuan Ku, Yichin Liu
