Medical image processing apparatus, medical image processing method, and medical image processing system

A medical image processing method in a medical image processing apparatus, the method comprising:

• acquiring volume data;
• setting a three-dimensional region in the volume data;
• acquiring three vectors orthogonal to each other from the three-dimensional region;
• calculating three surfaces to which the vectors are normal lines;
• generating three cross-sectional images of the three-dimensional region by setting the respective surfaces as cross-sections;
• displaying the generated cross-sectional images on a display;
• shifting at least one surface in parallel along the corresponding normal line;
• regenerating a cross-sectional image in which the shifted surface is a cross-section;
• and
• displaying the regenerated cross-sectional image on the display.
