Abstract: This invention provides an image processing method for projecting a virtual ray onto volume data to create an image and making it possible to realize speeding up without performing preprocessing. A virtual ray 22 is projected from an eye O onto an object 21, a position P at which the remaining light amount of the virtual ray 22 first attenuates is acquired, and a traveling distance d of the virtual ray 22 at the position P is acquired. To project an adjacent virtual ray 23, the virtual ray 23 is projected from a position O2 offset distance ?d smaller than the traveling distance d from the eye O by a predetermined value. Thus, when projection processing is performed, depth information d of the position P at which a first object is acquired on the virtual ray is stored and an adjacent virtual ray is projected from the position O2 offset ?d slightly smaller than the depth d, thereby skipping calculation.

Abstract: When the user presses an Alt key, the mode makes a transition to a property value switching mode and all annotations are made visible. At this time, the originally invisible annotations with the visibility properties set to invisible are drawn translucently. That is, a scanner name, a color bar, and a patient name which are not visible in a normal mode are drawn translucently. Thus, the user presses the Alt key, whereby the mode can be switched to the visible switching mode of drawing all objects, so that the user can promptly designate the annotation whose visibility property is to be changed and can smoothly conduct a medical diagnosis with an image.
