A medical image processing device according to an embodiment includes a first reconstruction unit, a second reconstruction unit, and an image combining unit. The first reconstruction unit generates a first reconstructed image on the basis of an X-ray collection image using a first reconstruction filter. The second reconstruction unit generates a second reconstructed image on the basis of the X-ray collection image, using a second reconstruction filter having a high-frequency emphasis effect more than that of the first reconstruction filter. The image combining unit combines the first reconstructed image with the second reconstructed image.
