Patent number: 10695145Abstract: A system for performing a scanning session of a patient's body, the system comprising: a radiation source; a radiation sensor; a patient positioner for placing the patient between the radiation source and the radiation sensor in a fixed position during each scan; at least one Pseudo-Random Grid (PRG) comprising randomly spaced perpendicular gridlines, the PRG being at least partially radiopaque and positioned between the radiation source and the radiation sensor in a fixed manner with respect to the patient positioner during the scanning session, wherein at least one of said radiation source and said radiation sensor is configured to move independently, and wherein at least one of said radiation source and said radiation sensor is moved to multiple different positions during the scanning session such that energy emitted from the radiation source passes through said PRG and said patient's body and collected by a surface of said radiation sensor.Type: GrantFiled: May 17, 2018Date of Patent: June 30, 2020Assignee: CMT MEDICAL TECHNOLOGIES LTD.Inventors: Dmitry Samsonov, Ami Ben Hayun

Patent number: 7260170Abstract: An adaptive CT data acquisition system and technique is presented whereby radiation emitted for CT data acquisition is dynamically controlled to limit exposure to those detectors of a CT detector assembly that may be particularly susceptible to saturation during a given data acquisition. The data acquisition technique recognizes that for a given subject size and position that pre-subject filtering and collimating of a radiation beam may be insufficient to completely prevent detector saturation. Therefore, the present invention includes implementation of a number of CT data correction techniques for correcting otherwise unusable data of a saturated CT detector. These data correction techniques include a nearest neighbor correction, off-centered phantom correction, off-centered synthetic data correction, scout data correction, planar radiogram correction, and a number of others.Type: GrantFiled: January 25, 2007Date of Patent: August 21, 2007Assignee: General Electric CompanyInventors: Jerome Stephen Arenson, David Ruimi, Evgeny Drapkin, Dmitry Samsonov, Bruno K.
