Patent number: 11854122Abstract: A nuclear medicine (NM) multi-head imaging system is provided that includes a gantry, detector units, and at least one processor. The gantry defines a bore. The detector units are mounted to the gantry and configured to rotate as a group with the gantry around the bore in rotational steps, with each detector unit configured to sweep about a corresponding axis and acquire imaging information while sweeping about the corresponding axis. The at least one processor is coupled to the detector units and configured to determine a region of interest (ROI) of the object to be imaged; determine a sweeping configuration based on the size of the ROI; determine a rotational movement configuration for the gantry using the determined sweeping configuration; and control the gantry and the set of detector units to utilize the determined rotational movement and sweeping configurations during acquisition of imaging information.Type: GrantFiled: September 27, 2021Date of Patent: December 26, 2023Assignee: General Electric CompanyInventors: Yariv Grobshtein, Michal Maria Merman, Shai Wald, Raz Carmi

Patent number: 11151758Abstract: A system is provided that includes a gantry, detector units, and at least one processor. The gantry defines a bore. The plural detector units are mounted to the gantry and configured to rotate as a group with the gantry in rotational steps. Each detector unit is configured to acquire imaging information while sweeping about a corresponding axis. The at least one processor is configured to determine a region of interest (ROI) of an object; identify a set of detector units; for the identified set of detector units, determine a sweeping configuration that results in a predetermined percentage of projection pixels receiving information from the ROI; determine a rotational movement configuration for the gantry using the determined sweeping configuration; and control the gantry and the set of detector units to utilize the determined rotational movement and sweeping configurations during acquisition of imaging information.Type: GrantFiled: November 7, 2018Date of Patent: October 19, 2021Assignee: General Electric CompanyInventors: Yariv Grobshtein, Michal Maria Merman, Shai Wald, Raz Carmi

Patent number: 10667771Abstract: Nuclear medicine (NM) imaging system includes a plurality of detector assemblies that each have a movable arm and a detector head that is coupled to the movable arm. The movable arm is configured to move the detector head toward and away from an object. The NM imaging system also includes at least one processor configured to determine a body contour of the object and determine an acquisition configuration using the body contour. The acquisition configuration includes at least three of the detector heads positioned in a dense group that borders the body contour. The detector heads in the dense group are primary detector heads. The at least one processor is also configured to move at least one of the object or one or more of the primary detector heads so that the primary detector heads are in the dense group near the object.Type: GrantFiled: January 15, 2019Date of Patent: June 2, 2020Assignee: General Electric CompanyInventors: Yariv Grobshtein, Shai Wald, Gillan Michael Grimberg, Ken Efrati, Jean-Paul Bouhnik

Patent number: 10049468Abstract: A method for volumetric image reconstruction of data collected from a plurality of radiation beams emitted from axially offset positions includes receiving projection data from at least two radiation beams emitted from axially offset positions, defining a first boundary between a first region irradiated only by a first beam of the at least two radiation beams and a second region irradiated by both the first beam and a second beam of the at least two radiation beams, defining a weighting function as a function of the first boundary, and reconstructing a volumetric image from the data that is weighted with the weighting function. Each beam moves on a circular trajectory and radiates at a plurality of view angles over the circular trajectory.Type: GrantFiled: November 26, 2014Date of Patent: August 14, 2018Assignee: Arineta Ltd.Inventors: Amir Finkel, Shai Wald
