20090196474 | IMAGE PROCESSING APPARATUS AND METHOD THEREOF - A position specifying unit specifies three diagnostic positions corresponding to respective vertexes of a reference triangle on a myocardial boundary in a diagnostic image, a calculating unit matches three training positions with the three diagnostic positions for each of a plurality of training images and compares the diagnostic image with training myocardial area boundary data to obtain a similarity, and an output unit outputs training myocardial area boundary data having the highest similarity. | 08-06-2009 |
20150084959 | MEDICAL IMAGE DIAGNOSIS APPARATUS AND IMAGE DISPLAY APPARATUS - A medical image diagnosis apparatus according to an embodiment includes a controller. The controller generates a plurality of candidates for a first cross-sectional image from three-dimensional image data obtained by taking images of a heart. The controller generates, from the three-dimensional image data, one or more second cross-sectional images each of which intersects the candidates for the first cross-sectional image. The controller displays in parallel on a display, the candidates for the first cross-sectional image, as well as the second cross-sectional images on each of which information is superimposed. The information indicates positional relationships between the candidates for the first cross-sectional image and the second cross-sectional image. | 03-26-2015 |
20150094516 | MEDICAL IMAGE PROCESSING DEVICE, TREATMENT SYSTEM AND MEDICAL IMAGE PROCESSING METHOD - According to an embodiment, a medical image processing device includes a processor, and a memory. The memory that stores processor-executable instructions that, when executed by the processor, cause the processor to execute acquiring a first perspective image of a subject viewed in a first direction; setting a first region and a second region on the first perspective image, the first region including a first group of pixels around a target pixel, the second region including a second group of pixels, the second group including a pixel not included in the first group; calculating a likelihood of the target pixel, wherein the likelihood increases as a difference between pixel values included in the first group decreases and a difference between pixel values of the first group and the second group increases; and detecting a position of an object in the subject based on the likelihood. | 04-02-2015 |
20150154757 | IMAGE PROCESSOR, TREATMENT SYSTEM, AND IMAGE PROCESSING METHOD - According to an image processor of one embodiment, a first acquirer acquires a first perspective image of a target viewed in a first direction. A second acquirer acquires a second perspective image of the target viewed in a second direction at a time different from when the first acquirer acquires the first perspective image. The second direction is substantially the same as the first direction. The second time is different from the first time. A point acquirer acquires first information indicating a first position of a first point on the first perspective image, and a second information indicating a second position of a second point on the second perspective image. An image generator generates an image that is based on the first and second perspective images, wherein a first coordinate of the first perspective image is changed so that the first point corresponds to the second point. | 06-04-2015 |
20150238149 | MAGNETIC RESONANCE IMAGING APPARATUS - A magnetic resonance imaging apparatus includes a controller and a deriving unit. The controller performs first imaging for acquiring first image data on a region including a target and the diaphragm, second imaging for acquiring, with application of motion detection pulses for detecting a respiratory phase, second image data including the target at a first respiratory phase and third image data including the target at a second respiratory phase different from the first respiratory phase, and third imaging for acquiring fourth image data. The deriving unit detects the position of the diaphragm from the first image data and derives a region to which the motion detection pulses are applied. In the performing of the second imaging, the controller detects a respiratory phase by the application of the detection pulses and controls timings at which the second image data and the third image data are acquired. | 08-27-2015 |
20150253407 | IMAGE PROCESSING APPARATUS, MAGNETIC RESONANCE IMAGING APPARATUS, AND IMAGE PROCESSING METHOD - An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to generate, from three-dimensional medical image data, a first cross-sectional image and a second cross-sectional image intersecting the first cross-sectional image and is configured to change display locations of the first cross-sectional image and the second cross-sectional image on a display, in conjunction with a change in an intersecting location of the first and the second cross-sectional images. | 09-10-2015 |
20150279111 | IMAGE PROCESSOR, TREATMENT SYSTEM, AND IMAGE PROCESSING METHOD - According to some embodiments, an image processor of an embodiment has an imaging parameter acquirer and a virtual perspective image generator. The imaging parameter acquirer acquires an imaging parameter which is used by a radiographic imaging apparatus in capturing a perspective image of a target. The virtual perspective image generator determines a method of generating a virtual perspective image from volume data acquired by capturing the target in accordance with the imaging parameter. The virtual perspective image generator generates the virtual perspective image from the volume data in accordance with the determined method. | 10-01-2015 |
20150305707 | ULTRASONIC DIAGNOSTIC APPARATUS, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD - According to an embodiment, an ultrasonic diagnostic apparatus includes an acquirer, first and second generators, and a display controller. The acquirer acquires a 3D ultrasonic image including a heart. The first generator generates a first cross-sectional image of the 3D ultrasonic image including a first axis passing through a second portion in the 3D ultrasonic image and including a third portion. The second portion is a portion by which one of blood inflow into a first portion which is an atrium or a ventricle and blood outflow from the first portion is performed. The third portion is a portion by which another of the blood inflow and the blood outflow is performed. The second generator generates a second cross-sectional image of the 3D ultrasonic image which includes a second axis passing through the third portion and which intersects with the first cross-sectional image. The display controller displays the cross-sectional images. | 10-29-2015 |
