Stereoroentgenographic diagnostic apparatus

Abstract

Abstract PURPOSE: To dispense with special glasses and to perform stereoscopic confirmation at an arbitrary angle, by providing the first means for obtaining the stereoscopic image of an specimen on the basis of the transmission data of the specimen of X-rays allowed to irradiate the specimen in two different directions, the second means for calculating the data of the image in the depth direction thereof to obtain three- dimensional data and the third means for performing the image display based on the three-dimensional data. CONSTITUTION: An image system 17 obtains the stereoscopic image of an object P to be examined on the basis of the transmission data of the specimen of X-rays allowed to irradiate the object P to be examined in two different directions. A data processing part 23 performs the data processing of left and right images according to predetermined algorithm and has not only a CPU but also a pre-processing means 21 and a post-processing means 22. As pre-processing, for example, the subtraction processing between images before and after the injection of a contrast medium, the contour detection processing of the images or the like are designated. The post-processing means 22 calculates the data of the images in the depth direction thereof by the matching processing of the taken-in stereoscopic image to obtain three-dimensional data. A display part 24 performs the image display based on the processing output of the data processing part 23. COPYRIGHT: (C)1989,JPO&Japio
