Publication number: 20180360419Abstract: A single hand operation ultrasound probe array is provided. The single ultrasound probe array places individual transducers, each having different transducer characteristics, on sheaths that fit over fingers of a user. By the user positioning their fingers differently, different transducers are selected for use, enabling the user to switch between multiple different center frequencies, or other different transducer configurations, based on the positioning of the fingers of the user relative to the patient. The ultrasound probe array is configured with wired or wireless communication to an ultrasonic machine to receive the probe signals and interpret.Type: ApplicationFiled: June 15, 2017Publication date: December 20, 2018Inventors: Xun Zhu, Changguo Ji, William Wong, Xingbai He

Publication number: 20170340298Abstract: A foldable biplane G-arm for use with x-ray imaging and fluoroscopic imaging. The system includes a gantry that supports imaging machinery to allow two bi-planar imaging beams to be taken simultaneously or without movement of the equipment and/or patient. Additionally, the system provides a G-arm gantry with a folding arm configuration that can solve prominent problems with traditional C-arm and G-arm gantries. In particular, the folding arm enables the G-arm of the present invention to reduce or eliminate obstacles between surgeons and nurses and more easily adapt for insertion of surgical tables into the system for imaging procedures by pivoting out and away from a center focus point of the support gantry to provide improved access for moving patient tables into and out of position for imaging the patient.Type: ApplicationFiled: May 16, 2017Publication date: November 30, 2017Inventors: Changguo Ji, Li'an Yuan, Xingbai He, Xun Zhu

Patent number: 9498178Abstract: A method for performing reconstruction for a region of interest (ROI) of an object is provided. The method includes designating the ROI within the object, the ROI being located within a scan field of view (FOV) of a combined third- and fourth-generation CT scanner, the CT scanner including fixed photon-counting detectors (PCDs), and an X-ray source that rotates about the object in synchronization with a rotating detector. Further, the method includes determining, for each PCD, as a function of view angle, an on/off timing schedule, based on a size and location of the designated ROI, and performing a scan to obtain a first data set from the rotating detector and a second data set from the plurality of PCDs, while turning each PCD on and off according to the determined schedule. Finally, the method includes performing reconstruction using the first and second data sets to obtain ROI spectral images.Type: GrantFiled: January 7, 2016Date of Patent: November 22, 2016Assignee: Toshiba Medical Systems CorporationInventors: Changguo Ji, Yuexing Zhang, Xiaolan Wang, Daniel Gagnon
