20090028289 | X-RAY CT APPARATUS - A CT value of an image within a region of interest is calculated with time. While the calculated CT value does not exceed a predetermined threshold value, a reconstruction mode used when an image is reconstructed from projection data is set to half reconstruction. On the other hand, while the calculated CT value exceeds a predetermined threshold value, the reconstruction mode is set to segment reconstruction. | 01-29-2009 |

20110158380 | X-RAY COMPUTED TOMOGRAPHY APPARATUS - In one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, an X-ray detector, a rotating mechanism, a high voltage generating unit, a reconstruction processing unit, a projection image generating unit configured to generate a projection image based on output from the X-ray detector, an image display unit, and a fluoroscopy control unit configured to control the rotating mechanism, the high voltage generating unit, the X-ray detector, the projection image generating unit and the image display unit to implement stereo fluoroscopy. | 06-30-2011 |
20120320167 | IMAGE PROCESSING SYSTEM AND METHOD - An image processing system according to an embodiment includes a display unit capable of displaying stereoscopic images by displaying a group of parallax images and a display control unit. The display control unit displays an operation screen for receiving operations on medical image data on the display unit, displays selection information for selecting medical image data on the operation screen, and controls whether the selection information will be displayed as a stereoscopic image or a planar image depending on the content of medical image data selected by the selection information. | 12-20-2012 |
20130010922 | X-RAY CT APPARATUS AND IMAGE PROCESSING METHOD - An X-ray CT apparatus has a scanner, a pre-scan control unit, an image generating unit, a region setting unit and a timing sensing unit. The pre-scan control unit controls an operation of the scanner to perform a pre-scan. The image generating unit generates image data of the object based upon the pre-scan. The region setting unit sets, on the basis of the image data, a region of interest, and a larger region encompassing the region of interest and a region around the region of interest and being used to determine whether or not a high pixel value region exists. The timing sensing unit senses, if the larger region does not include a pixel value higher than a first threshold, a timing to start a main scan, at which a pixel value of the region of interest exceeds a second threshold after injection of the contrast medium agent is started. | 01-10-2013 |
20130012814 | IMAGE DIAGNOSTIC APPARATUS AND METHOD OF CONTROLLING THE SAME - An image diagnostic apparatus of an embodiment includes a density change acquisition unit, a trigger generating unit and a control unit. The density change acquisition unit is configured to acquire data corresponding to a temporal change in density of a contact agent injected into an object. The trigger generating unit is configured to generate a trigger when abnormal data has been detected by a first threshold processing of the data. The trigger is generated by a second threshold processing of data other than the abnormal data. The control unit is configured to perform a control of contrast imaging for the object based on the trigger. | 01-10-2013 |
20130182821 | X-RAY CT (COMPUTED TOMOGRAPHY) DEVICE - As one embodiment, the X-ray CT device comprises an X-ray tube, a tube voltage generator, an X-ray detector, a data accumulating unit, and an image processing unit. The tube voltage generator applies said tube voltage to the X-ray tube. The tube voltage controlling unit controls the tube voltage generator means so as to periodically alternate the tube voltage. The X-ray detector is arranged across a subject from the X-ray tube, and detects the X-rays penetrating the subject. The data accumulating unit accumulates first sampling data when a high voltage is applied to said X-ray tube in one cycle by synchronizing with the change in said tube voltage from the data detected by said X-ray detector, and after a predetermined amount of time has passed from said accumulation, accumulates second sampling data when a low voltage is applied to said X-ray tube. The image processing unit creates images based on the accumulated first sampling data and second sampling data. | 07-18-2013 |
20130287260 | X-RAY CT APPARATUS, SUBSTANCE IDENTIFYING METHOD, AND IMAGE PROCESSING APPARATUS - An X-ray CT apparatus of an embodiment displays an image of the inside of an object based on projection data obtained by scanning the object, and comprises a generator, a converter, an image forming part and an identifier. The generator scans the object with each of X-rays of different energy levels and generates multiple projection data. The converter converts the multiple projection data into multiple new projection data corresponding to multiple reference substances. The image forming part reconstructs each of the multiple new projection data converted by the converter, thereby forming multiple reference substance images corresponding to the multiple reference substances. The identifier identifies a target substance based on a correlation of pixel values in the multiple reference substance images. | 10-31-2013 |
