Publication number: 20170263022Abstract: When a group of (pre-processed) projection data is stored into a projection-data storage unit, a Gaussian-based expansion-data creating unit creates a group of Gaussian-based expansion data that is expanded from each of the group of projection data through linear combination based on a plurality of Gaussian functions that is stored by a Gaussian-function storage unit and has different center points. A reconstruction-image creating unit then creates a reconstruction image by using the Gaussian-based expansion-data created by the Gaussian-based expansion-data creating unit, and stores the created reconstruction image into an image storage unit.Type: ApplicationFiled: June 2, 2017Publication date: September 14, 2017Applicant: TOSHIBA MEDICAL SYSYTEMS CORPORATIONInventors: Manabu TESHIGAWARA, Takuzo TAKAYAMA, Tomoyasu KOMORI, Takaya UMEHARA

Publication number: 20100271022Abstract: A receiving RF coil includes a coil element group having a figure-eight coil, a first loop coil arranged at the center of the figure-eight coil, and a second loop coil partially overlaid on the first loop coil. Furthermore, a path switching control unit switches the transmitting paths of a signal so that the signal can be received and/or transmitted with a combination of the first loop coil and the second loop coil or a combination of the figure-eight coil and the first loop coil.Type: ApplicationFiled: April 16, 2010Publication date: October 28, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA MEDICAL SYSYTEMS CORPORATIONInventors: Shinji MITSUI, Hiroki MOTOHASHI

Publication number: 20100201360Abstract: When the settings of the region of interest are received from the operator, the measurement data acquisition control unit performs control so that an image for generating profile data is taken, and the data processing unit generates profile data in the encoding directions of the set region of interest. Then, the field-of-view setting unit sets the field of view in each of the encoding directions, based on the relationship between the dimensions of the subject P in the encoding directions that are calculated from the profile data of the encoding directions and the dimensions of the region of interest in the corresponding encoding directions, by use of coefficients stored in the coefficient storage unit.Type: ApplicationFiled: February 5, 2010Publication date: August 12, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA MEDICAL SYSYTEMS CORPORATIONInventor: Yoshinari MORITA

Publication number: 20100152568Abstract: When determined that a body-motion is produced before starting a main-imaging, a sequence-switching control-unit controls operation so as to switch from a usual-imaging sequence to a body-motion adaptive-sequence corresponding to an imaging-portion of a subject P by referring to a body-motion adaptive-sequence storage-unit. Moreover, upon a determination that a body-motion is produced during the main-imaging according to the usual-imaging sequence, the sequence-switching control-unit refers to a collected-data storage-unit, and controls operation so as to perform a retake by switching to the body-motion adaptive-sequence if an already-collected data-volume is less than a predetermined volume.Type: ApplicationFiled: December 2, 2009Publication date: June 17, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA MEDICAL SYSYTEMS CORPORATIONInventor: Katsutoshi KOKUBUN

Publication number: 20100085053Abstract: A feedforward control unit predicts the maximum value of the temperature of a gradient coil based on a power duty and a scan time of a pulse sequence, and a present temperature of the gradient coil. When the maximum value exceeds a predetermined upper limit, the feedforward control unit then instructs a temperature adjusting unit to start a water circulation in a chiller at the start of a prescan, and the temperature adjusting unit starts the water circulation based on the instruction.Type: ApplicationFiled: September 25, 2009Publication date: April 8, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA MEDICAL SYSYTEMS CORPORATIONInventors: Masateru IWASA, Kazuto NOGAMI, Tomoyuki YOSHIDA, Fumitoshi KOJIMA, Yoshitomo SAKAKURA, Kohei ADACHI

Publication number: 20100002839Abstract: Positioning images are created by a projection-image creating unit before imaging, and the positioning images are grouped and stored by a projection-image storage unit for each preset. When imaging is started, a positioning-information calculating unit calculates positioning parameters using the positioning images stored in the projection-image storage unit. An analysis-image-for-synthesis creating unit creates an analysis image using the positioning parameters, and an analysis-image synthesizing and displaying unit synthesizes the analysis image with a live image and displays a synthesized image. When an imaging direction of an X-ray angiography apparatus is changed, a positioning-information updating unit directly updates the positioning parameters based on an amount of change of the imaging direction.Type: ApplicationFiled: June 17, 2009Publication date: January 7, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA MEDICAL SYSYTEMS CORPORATIONInventors: Tetsuya YOKOTA, Hitoshi YAMAGATA, Satoshi WAKAI
