20150250395 | MEDICAL IMAGE PROCESSING APPARATUS - According to one embodiment, a medical image processing apparatus includes first specifier, second specifier, determiner and display controller. First specifier collates an ischemic region calculated from a blood vessel visualized into a three-dimensional image in a plurality of phases with a dominating region of the blood vessel, and specifies a culprit vessel in the ischemic region. Second specifier specifies a culprit stenosis in the culprit vessel based on a pressure index calculated from the blood vessel. Determiner determines a connection position to connect a bypass vessel that makes a detour around the culprit stenosis. Display controller displays the determined connection position on a display. | 09-10-2015 |

The processing circuitry converts the plurality of FFR distribution maps into a plurality of corresponding color maps, respectively. The display displays a plurality of superposed images obtained by superposing the plurality of color maps and the plurality of morphological images respectively corresponding in phase to the plurality of color maps. The display restricts display targets for the plurality of color maps based on the plurality of FFR distribution maps or the plurality of morphological images. | 09-17-2015 |
20150356734 | BLOOD VESSEL ANALYSIS APPARATUS, MEDICAL IMAGE DIAGNOSIS APPARATUS, AND BLOOD VESSEL ANALYSIS METHOD - According to one embodiment, a structuring circuitry temporarily structures a dynamical model of analysis processing based on the time-series medical image. The identification circuitry identifies a latent variable of the dynamical model so that at least one of a prediction value of a blood vessel morphology and a prediction value of a bloodstream based on the temporarily structured dynamical model is in conformity with at least one of an observation value of the blood vessel morphology and an observation value of the bloodstream measured in advance. The analysis circuitry analyzes the dynamical model to which the identified latent variable is allocated. | 12-10-2015 |
20160078677 | MEDICAL IMAGE PROCESSING APPARATUS AND MEDICAL IMAGE PROCESSING METHOD - According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry extracts a core line of a tubular structure from three dimensional medical image data. For each section of interest of a plurality of sections of interest, the section of interest crossing the core line, being a tubular cross-section of the tubular structure, and including a portion of interest, the processing circuitry sets a straight line in the section of interest crossing the core line and passing through the portion of interest included in the section of interest as a first cut-off line. Further, the processing circuitry sets a curved plane such that the curved plane passes through a plurality of first cut-off lines being set in the corresponding plurality of sections of interest, and the processing circuitry generates a reconstruction image along the set curved plane. | 03-17-2016 |
