Image processing apparatus, image processing method, and program

An image processing method executed by an image processing apparatus, the method comprising:

• acquiring, by a processor, volume data;
• acquiring, by the processor, a coordinate of a feature point of an object in the volume data;
• setting a projection plane in the volume data, a projection range for generating a projection image from the volume data, which includes the projection plane and a first distance before and first distance behind the projection plane in a direction of a line normal to the projection plane, a display range of feature points to be superimposed on the projection image, which includes said projection plane and a second distance before and a second distance behind the projection plane in a direction of a line normal to the projection plane, and adjusting at least one of the projection range and the display range such that the projection range and the display range satisfy a predetermined relationship in which the whole projection range is included in the display image;
• and
• generating, by the processor for projection, the projection image from the volume data according to the projection range and superimposing the feature point in the display range on the projection image.

A non-transitory storage medium non-temporarily storing a program configured to cause a computer to execute a process, the process comprising:

• acquiring, by a processor, volume data;
• acquiring, by the processor, a coordinate of a feature point of an object in the volume data;
• setting a projection plane in the volume data, a projection range for generating a projection image from the volume data, which includes the projection plane and a first distance before and first distance behind the projection plane in a direction of a line normal to the projection plane, a display range of feature points to be superimposed on the projection image, which includes said projection plane and a second distance before and a second distance behind the projection plane in a direction of a line normal to the projection plane, and adjusting at least one of the projection range and the display range such that the projection range and the display range satisfy a predetermined relationship in which the whole projection range is included in the display image;
• and
• generating, by the processor for projection, the projection image from the volume data according to the projection range and superimposing the feature point in the display range on the projection image.
