There is provided a medical image processing apparatus which includes a first extraction unit configured to extract coronary arteries depicted in images of a plurality of time phases relating to the heart, and to extract at least one stenosed part depicted in each coronary artery; a calculation unit configured to calculate a pressure gradient of each of the extracted coronary arteries, based on tissue blood flow volumes of the coronary arteries; a second extraction unit configured to extract an ischemic region depicted in the images; and a specifying unit configured to specify a responsible blood vessel of the ischemic region by referring to a dominance map, in which each of the extracted coronary arteries and a dominance territory are associated, for the extracted ischemic region, and to specify a responsible stenosis, based on the pressure gradient corresponding to a stenosed part in the specified responsible blood vessel.

Medical image processing apparatus and medical image processing method

According to embodiment, an image processing apparatus comprising a specifying unit and a display controller. The specifying unit that specifies an acquisition position of an indicator relating to blood flow on a blood vessel-containing image collected by a medical image diagnostic apparatus. The display controller that displays the acquisition position on the blood vessel-containing image and displays the indicator on a display unit in association with the acquisition position.

Image processing apparatus, medical image diagnostic apparatus, and blood pressure monitor

According to one embodiment, a medical image diagnostic apparatus includes a storage memory, processing circuitry, and a display. The storage memory stores data of a plurality of FFR distribution maps constituting a time series regarding a coronary artery, and data of a plurality of morphological images corresponding to the time series. 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.

Medical image diagnostic apparatus

A medical-image processing apparatus and a medical-image diagnostic apparatus according to an embodiment include an acquisition unit, a generation unit, an identification unit, and a display control unit. The acquisition unit acquires a medical image containing a blood vessel collected by the medical-image diagnostic apparatus. The generation unit generates an anatomical structure model based on the medical image acquired by the acquisition unit. The identification unit identifies a position, on the medical image, of an index relating to blood flow analyzed through fluid analysis using the anatomical structure model. The display control unit displays the position of the index on the medical image, and also displays the index associated with the position of the index on the medical image.

Medical-image processing apparatus and medical-image diagnostic apparatus

A medical image diagnostic apparatus according to an embodiment includes an estimation unit, an extraction unit, and a specifying unit. The estimation unit estimates a position of a plaque in a blood vessel based on data of CT images constituting a time series, with the blood vessel being enhanced by a contrast medium. The extraction unit extracts regions constituting the blood vessel from the CT images. The specifying unit specifies stress values respectively corresponding to the regions based on a moving displacement due to cardiac pulsation in each of the regions, and specifies an exfoliation risk of the plaque based on an index indicating hardness of the plaque and the stress value in the region corresponding to the position of the plaque.

In one embodiment, a medical image diagnostic apparatus includes a memory circuit; a display; and processing circuitry configured to acquire medical images of an object at respective time phases, detect respective positions of a treatment device in the medical images, acquire biological information from the medical images, compute biological indexes indicating degree of a treatment effect for the respective time phases based on the biological information, cause the memory circuit to store the biological indexes and the respective positions of the treatment device in the medical images such that each biological index is associated with a position of the treatment device in a medical image, from which the biological information corresponding to the each biological index is acquired, for the respective time phases, and cause the display to display each position of the treatment device and a biological index associated with the each position of the treatment device.

Medical image diagnostic apparatus, and medical image processing apparatus

A centerline extraction unit extracts at least two coronary artery centerline structures from at least two images respectively corresponding to at least two cardiac phases concerning a heart, an interpolation processing unit interpolates coronary artery centerline structures concerning other cardiac phases from the at least two extracted coronary artery centerline structures to generate coronary artery centerline structures respectively corresponding to a plurality of cardiac phases throughout one heartbeat of the heart, and a displacement distribution calculation unit calculates a plurality of displacement distributions between the respective cardiac phases from a plurality of coronary artery centerline structures throughout the one heartbeat.

Medical image processing apparatus

In one embodiment, an image processing device includes memory circuitry configured to store a program; and processing circuitry configured, by executing the program, to extract an outer wall of a tubular structure by using a fat image obtained by a water/fat separation method of magnetic resonance imaging, and generate a tubular-structure wall image in which a wall of the tubular structure is distinguished, based on the outer wall.

Image processing device and MRI apparatus

An X-ray image diagnosis apparatus includes an X-ray tube, an X-ray detector, a fluid information acquisition unit, a registration unit, and a capturing direction controller. The X-ray tube emits X-rays toward a subject. The X-ray detector detects the X-rays having passed through the subject. The fluid information acquisition unit acquires fluid information on a target site including a region of interest of the subject captured by an ultrasound image diagnosis apparatus. The registration unit extracts position information of a probe of the ultrasound image diagnosis apparatus. The capturing direction controller controls capturing direction for capturing the target site based on the position information and a direction in which a fluid flows indicated by the fluid information.
