Bildverarbeitungsvorrichtung und bildverarbeitungsverfahren

According to one embodiment, a medical image processing apparatus includes a storage unit (40), a generation unit (50), and a segmentation unit (52). The storage unit (40) configured to store a first medical image and second medical image regarding the same imaging region imaged at different times. The generation unit (50) configured to generate numerical data representing a frequency of a combination of a pixel value of the first medical image and a pixel value of the second medical image at the same coordinates. The segmentation unit (52) configured to divide the second medical image into a plurality of image areas by using the generated numerical data.
