Abstract: A medical image processing apparatus includes a control unit for grouping input medical images from every same examination of a same patient by using accompanying information of the input medical images, and for saving the grouped medical images in a storage unit. When a medical image is newly input, the control unit collates accompanying information of the newly input medical image with the accompanying information of the grouped medical images to thereby judge whether the newly input medical image has been obtained by additional radiography or by re-radiography. The control unit regroups the newly input medical image and the grouped medical images from a same examination of a same patient by using the accompanying information, when the control unit judges that the newly input medical image has been obtained by either additional radiography or re-radiography.
