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

Patent number: 11766231Abstract: A system and method for improved image acquisition of multiple pulsed X-ray source-in-motion tomosynthesis imaging apparatus by generating the electrocardiogram (ECG) waveform data using an ECG device. Once a representative cardiac cycle is determined, system will acquire images only at rest period of heart beat. Real time ECG waveform is used as ECG synchronization for image improvement. The imaging apparatus avoids ECG peak pulse for better chest, lung and breast imaging under influence of cardiac periodical motion. As a result, smoother data acquisition, much higher data quality can be achieved. The multiple pulsed X-ray source-in-motion tomosynthesis machine is with distributed multiple X-ray sources that is spanned at wide scan angle. At rest period of one heartbeat, multiple X-ray exposures are acquired from X-ray sources at different angles. The machine itself has capability to acquire as many as 60 actual projection images within about two seconds.Type: GrantFiled: November 10, 2021Date of Patent: September 26, 2023Assignee: AIXSCAN INC.Inventors: Jianqiang Liu, Manat Maolinbay, Chwen-yuan Ku, Linbo Yang

Patent number: 11730439Abstract: An X-ray imaging system using multiple pulsed X-ray sources in motion to perform high efficient and ultrafast 3D radiography using an X-ray flexible curved panel detector is presented. There are multiple pulsed X-ray sources mounted on a structure in motion to form an array of sources. The sources move simultaneously relative to an object on a predefined arc track at a constant speed as a group. Each individual X-ray source can move around its static position at a small distance. When an individual source has a speed equal to group speed, but with opposite moving direction, the individual source and detector are activated. This allows source to stay relatively standstill during activation. The operation results in reduced source travel distance for each individual source. 3D radiography image data can be acquired with much wider sweep angle in much shorter time, and image analysis can also be done in real-time.Type: GrantFiled: October 20, 2021Date of Patent: August 22, 2023Assignee: AIXSCAN, Inc.Inventors: Jianqiang Liu, Manat Maolinbay, Chwen-yuan Ku, Linbo Yang
