Three-dimensional image constructing method using X-ray apparatus
First Claim
1. A three-dimensional image constructing method using an X-ray apparatus, said X-ray apparatus including an X-ray irradiator for irradiating X-rays to a subject, an image multiplier tube for causing an image to be formed thereon by X-rays having been transmitted through the subject, an image selection unit for selecting a specific region from the image multiplied by the image multiplier tube 140, and a photographing unit for obtaining the image of the specific region selected by the image multiplier tube, comprising:
- a setting step of setting a construction space of a subject and information for the construction space;
an image obtaining step of obtaining a plurality of transmission images of the subject;
an image processing step of calculating data of the construction space on the basis of the information for the construction space set at the setting step and the transmission images obtained at the image obtaining step; and
a constructing step of constructing the construction space on the basis of the data calculated at the image processing step.

Abstract
Disclosed herein is a three-dimensional image constructing method using an X-ray apparatus. In the three-dimensional image constructing method, a construction space of a subject and information for the construction space are set. Thereafter, a plurality of transmission images of the subject are obtained. The data of the construction space are calculated on the basis of the information for the construction space set at the setting step and the transmission images obtained at the image obtaining step. The construction space is constructed on the basis of the data calculated at the image processing step.
