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 of a subject;
• displaying a three-dimensional image by rendering the acquired volume data;
• displaying a first object showing (i) a point on a body surface of the subject and (ii) a direction with respect to the volume data in the three-dimensional image;
• displaying a two-dimensional image of a surface, wherein the surface includes the point on the body surface and is defined based on the direction, in the volume data;
• acquiring information of an operation to change display of the two-dimensional image;
• and
• moving the point on the body surface along the body surface of the subject based on the operation to update display of the first object and the two-dimensional image.
