A three dimensional image processing apparatus includes a storage unit storing data of images in different radiographing directions together with information concerning cardiac phases, a key image selection unit selecting key images from the images, a feature point designation unit designatting feature points on the selected key images in accordance with operation by an operator, and an image reconstruction unit reconstructing a three dimensional image from the images on the basis of positions of the designated feature points, wherein the key image selection unit selects, as the key images, a pair of images which are located at the same cardiac phase and whose radiographing directions are different by a substantially predetermined angle and images spaced apart from each other by an angle obtained by substantially equally dividing an interval between the pair of images by a predetermined number.

According to one embodiment, an image processing apparatus includes a storage unit, a specifying unit, an extraction unit and a setting processing unit. The storage unit stores first X-ray image data in which a blood vessel of an object is not visually enhanced, and second X-ray image data in which the blood vessel is visually enhanced. The specifying unit specifies a catheter image included in the first fluoroscopic image by performing image processing of the first X-ray image data. The extraction unit extracts a blood vessel region included in the second fluoroscopic image by performing image processing of the second X-ray image data. The setting processing unit sets a region of interest based on the position of end point of the catheter.

An image processing apparatus according to the present embodiment includes a correcting unit. The correcting unit identifies, based on an observation value of a residual contrast material component that is injected to a subject before a predetermined timing and remains in the subject, the residual contrast material component and a new contrast material component that is newly injected to the subject after the predetermined timing regarding a contrast material component that is included in an image, and corrects an observation value of the contrast material component included in the image.

A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires image data including image data of a blood vessel of a subject. The processing circuitry performs analysis related to the blood vessel by using the image data, and specifies a region of interest in the blood vessel based on a result of the analysis. The processing circuitry performs fluid analysis on a region other than the region of interest at a first accuracy, and performs fluid analysis on the region of interest at a second accuracy that is higher than the first accuracy.
