Continuous photographing and observing of a three-dimensional image.

摘要

A target (1) is continuously observed and a three-dimensional image of the target is recorded. A transmitter unit (4) irradiates a target (1) with suitable radiation and an image recording unit (5, 6) records radiation images of the target. A rotating unit (3) incrementally positions the target (1) between the transmitting (4) and image recording units (5, 6). Injecting means (10) places a contrast material into the target (1), a memory stores a first set of reference images of the target (1) for predetermined number of angular increments prior to injection of said contrast material and stores second set of contrast images for each angular increment of rotation of the target (1) after injection of the contrast material. An arithmetic unit (21) produces a set of drawn images of the target from the stored reference and contrast image data, and an indicator unit (29a,b) displays two drawn images of the target that are separated by a certain angular difference so that the two images can be viewed in three dimension using a stereo-scope (30).
