20120099776 | MEDICAL IMAGE PROCESSING APPARATUS - It is a subject to reduce the number of processing steps and shorten the processing time when specifying a branch position in a tubular structure, mainly the bronchus or blood vessel. A apparatus includes a storage unit which stores volume data concerning a 3D region of a subject as a target. A tomogram generation unit generates the data of slice images respectively corresponding to slices almost perpendicular to a predetermined reference axis from volume data files. A region extraction unit extracts regions associated with a target site from the plurality of slice images by using threshold processing. A position specifying unit specifies a position on the reference axis, wherein the number of extracted regions changes at the position. | 04-26-2012 |
20120263359 | MEDICAL IMAGE PROCESSING APPARATUS AND MEDICAL IMAGE PROCESSING PROGRAM - A medical image processing apparatus includes a first extraction part, an adding part, a first specifying part, and a second specifying part. The first extraction part extracts an air region from volume data after receiving volume data representing a region including an organ under observation. The adding part adds pixel values of the pixels in the air region along a predetermined projection direction to generate projection image data representing the distribution of the added value of pixel values. The first specifying part specifies a first characteristic point from the projection image data. The second specifying part specifies, as a second characteristic point, a point on a line passing a first characteristic point in an air region. | 10-18-2012 |

20140099013 | MEDICAL IMAGE-PROCESSING APPARATUS, X-RAY CT APPARATUS, AND A MEDICAL IMAGE-PROCESSING METHOD - A medical image-processing apparatus that corrects divergence, even in a case where divergence in CT numbers occurs throughout a plurality of sets of image data that have been acquired for anatomically identical areas because the observed object is undergoing shape-alteration. The apparatus includes an image data storage, an extractor, and a corrector. The image data storage stores respective sets of image data acquired by scanning a targeted region undergoing chronological shape-alteration in a subject, the scanning having been executed at predetermined respective timings. The extractor extracts image data that correspond to the targeted region out of each of the respective sets of image data. The corrector calculates degrees of shape-alteration of the targeted region in the respective extracted sets of images data and to correct CT numbers of the respective sets of image data extracted for the targeted region, based on calculated degrees. | 04-10-2014 |
20140171796 | NUCLEAR MEDICINE DIAGNOSTIC APPARATUS, DIAGNOSTIC IMAGING APPARATUS, AND IMAGE PROCESSING METHOD - According to one embodiment, a nuclear medicine diagnostic apparatus includes a counting unit, a region of interest setting unit, a normalization unit, and an image generation unit. The counting unit counts radiation emitted from radioisotopes in an imaging region of an object. The ROI setting unit sets a region of interest (ROI) in the imaging region. The normalization unit determines association between count values and pixel values of display pixels for the ROI in accordance with a distribution of the count values of the display pixels corresponding to the ROI. The image generation unit generates an image of the ROI based on the association between the count values and the pixel values for the ROI. | 06-19-2014 |
20140219416 | X-RAY COMPUTED TOMOGRAPHY APPARATUS, MEDICAL IMAGE PROCESSING APPARATUS, AND MEDICAL IMAGE PROCESSING METHOD - An X-ray computed tomography apparatus includes an X-ray tube, an X-ray detector, a volume data reconstruction unit, a lung field region specifying unit, a discrimination unit, an image generation unit, and a display unit.
