A medical image-processing apparatus according to an embodiment includes processing circuitry configured to determine a position of a feature point of a device in a first X-ray image, and generate a superimposed image in which a 3D model expressing the device is superimposed on the first X-ray image or a second X-ray image that is acquired later than the first X-ray image. The processing circuitry is configured to superimpose the 3D model on the first X-ray image or the second X-ray image at a position based on the position of the feature point.

Image processing apparatus, X-ray diagnostic apparatus, and image processing method

In one embodiment, a medical image processing apparatus used for a treatment using a device includes a memory configured to store a volume data of an object; and processing circuitry configured to acquire positional information of the device, set, in an X-ray image generated by imaging an object using X-ray, a region on which a volume-based 2D image generated from the volume data is to be superimposed, based on the positional information of the device, and generate a superimposed image by superimposing the volume-based 2D image on the set region in the X-ray image.

Medical image processing apparatus, X-ray diagnostic apparatus, and medical image processing method

A medical image processing apparatus according to an embodiment includes processing circuitry configured: to acquire a plurality of time series medical images; to determine a feature point in each of the plurality of medical images to calculate moving amounts of the determined feature point between the plurality of medical images; to set a weight coefficient with respect to each of the plurality of medical images, on the basis of the calculated moving amounts; and to perform an image processing process by using the plurality of medical images, on the basis of the weight coefficients.

An X-ray diagnostic apparatus according to an embodiment includes processing circuitry configured to acquire a plurality of X-ray images over time based on X-rays having passed through a subject injected with a contrast agent, to calculate a blood vessel region corresponding to an inflow path of the contrast agent leading to a predetermined position in the blood vessel region, based on a temporal transition of signal intensities of the contrast agent in the blood vessel region represented in the X-ray images, and to perform control to display the blood vessel region corresponding to the inflow path in a display mode that is different from that of a blood vessel region other than the inflow path on a display.
