Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray irradiator, a scatterer, a grid, and a detector. The X-ray irradiator irradiates X-rays. The scatterer is provided between the X-ray irradiator and an object, that scatters the irradiated X-rays. The grid is provided between the scatterer and the object, that transmits the scattered X-rays within a predetermined angular range. The detector detects X-rays transmitted through the object together with an incident angle of the X-rays.

Abstract: A breast X-ray imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry collects three-dimensional image data of a breast of a subject. The processing circuitry detects a lesion from the three-dimensional image data. The processing circuitry derives a puncture path for inserting a puncture needle into the breast, by analyzing linearity in three-dimensional distribution of the lesion and based on an analysis result of the linearity.

Abstract: According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry designates a region of interest in a first tomogram among multiple tomograms which are based on tomosynthesis imaging performed with a subject compressed in a first direction. The processing circuitry specifies a second tomogram corresponding to the region of interest from among multiple tomograms which are based on tomosynthesis imaging performed with the subject compressed in a second direction different from the first direction.
