Patent number: 7260172Abstract: 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, Evgeny Drapkin, Yanfeng Du, Lev Greenberg, Oded Meirav, David Ruimi, John Eric Tkaczyk, Xiaoye Wu

Patent number: 6193657Abstract: An imaging system and method for determining sensor position and orientation with respect to an object having a known three dimensional structure is disclosed. The sensor acquires an image of the known structure. Position and orientation of the sensor is determined by processing the image with formulas corresponding to the known structure. One embodiment of the present invention comprises an ultrasound training system and method for determining the position and orientation of an ultrasound probe with respect to a known three dimensional structure embodied in an ultrasound phantom. The ultrasound probe acquires a cross sectional or partial volume image of the ultrasound phantom. The image is processed to obtain a number of geometrical image parameters. Position and orientation of the ultrasound probe are calculated from the image parameters using formulas based on the known three dimensional structure. The determination of probe position and orientation may be enhanced using image de-correlation techniques.Type: GrantFiled: December 31, 1998Date of Patent: February 27, 2001Assignee: GE Medical Systems Global Technology Company, LLCInventor: Evgeny Drapkin

Patent number: 6139498Abstract: An ultrasound system comprises a front end subsystem and a back end subsystem. The back end subsystem processes data samples representative of the echo signals from the front end subsystem. The back end subsystem includes at least one microprocessor with registers that simultaneously store at least two data samples. The microprocessor performs parallel common arithmetic or logic instructions upon at least two ultrasound data samples in one register. The microprocessor may be configured to scan convert polar data samples to Cartesian pixel values. During scan conversion, one register simultaneously stores multiple polar data samples and another register simultaneously stores coefficients associated with the polar data samples. The microprocessor multiplies corresponding data samples and coefficients, and sums the product of the parallel multiplication operations in order to produce a Cartesian data sample associated with a pixel to be displayed on an image arranged in a Cartesian coordinate pattern.Type: GrantFiled: December 29, 1998Date of Patent: October 31, 2000Assignee: GE Diasonics Israel, Ltd.Inventors: Igor Katsman, Menachen Halmann, Evgeny Drapkin

Patent number: 6117078Abstract: A method and apparatus for providing a virtual volumetric ultrasound phantom to construct an ultrasound training system from any ultrasound system (hereafter "the ultrasound training system").The ultrasound system and method retrieve and display previously stored ultrasound data to simulate an ultrasound scanning session. A real ultrasound system acquires an image of an ultrasound phantom. The ultrasound image comprises ultrasound echo data for an image/scan plane representing a cross-section or partial volume of the ultrasound phantom. The ultrasound image is analyzed to identify image attributes that are unique for each image/scan plane. A portion of the previously stored data that corresponds to the image attributes is retrieved and displayed. In one embodiment, actual position and orientation of the acquired image/scan plane with respect to a known structure within the ultrasound phantom are determined by processing the image/scan plane to obtain a number of geometrical image parameters.Type: GrantFiled: December 31, 1998Date of Patent: September 12, 2000Assignee: General Electric CompanyInventors: Peter Lysyansky, Evgeny Drapkin
