Method and apparatus for displaying three-dimensional image
First Claim
1. A method of displaying a three-dimensional image, comprising the steps of:
- forming a first image, the first image including the three-dimensional image formed from a first plurality of tomographic images;
forming a second image, the second image including a second plurality of tomographic images that include at least one of the first plurality of tomographic images; and
displaying at least one of the first and second images.

Abstract
A three-dimensional image is displayed on a display in a central projection method based upon a viewpoint which is placed at the inside of an object and a line of sight. In this case, a plurality of tomographic images interposed between the viewpoint and a projection plane are sequentially arranged and displayed on a display screen. Polygon visual field frames are formed at points of intersection of projection lines forming a polygon pyramid and each tomographic image, and the visual field frames are displayed on the display screen. Thereby, the position of the viewpoint and the line of sight with respect to the currently-displayed three-dimensional image showing the inside of the object can be easily detected, and the part of the object which is being displayed can be easily recognized.
