Abstract: In an image processing apparatus, an extracting unit extracts mutually the same region of interest from each of a plurality of pieces of three-dimensional image data corresponding to mutually-different time phases. Further, a position determining unit determines, on the basis of feature points included in the pieces of three-dimensional image data, a position used for superimposing together the regions of interest extracted by the extracting unit from the pieces of three-dimensional image data, in substantially the same position of a subject. After that, a display controlling unit changes a display format of each of the regions of interest extracted by the extracting unit from the pieces of three-dimensional image data so as to be mutually different and causes a superimposed image to be displayed by superimposing the regions of interest together in the position determined by the position determining unit.

Abstract: 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.

Abstract: According to one embodiment, a medical image processing apparatus is configured to capture images of an observation object over time to obtain a three-dimensional image. The observation object includes a first hard tissue and a second hard tissue which are adjacent to each other. The medical image processing apparatus includes a control circuit, a plane acquisition unit, and an image generator. Under the control of the control circuit, the plane acquisition unit extracts the first hard tissue and the second hard tissue based on the three-dimensional image. The image generator generates, as an image for observation, a cross-sectional image of a plane including the first hard tissue and at least part of the second hard tissue or an image projected on a plane parallel to the plane including the first hard tissue and at least part of the second hard tissue based on the three-dimensional image.
