Title:
NON-ROTATING OBLIQUE-TYPE CT DEVICE AND METHOD FOR RESTORING THREE-DIMENSIONAL INTERNAL SHAPE IMAGE OF SUBJECT USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/004085
Kind Code:
A1
Abstract:
The present invention relates to a non-rotating oblique-type CT device comprising: a stage; an incident radiation forming portion for forming incident radiation to be emitted to a subject; a projection data detecting portion installed opposite the incident radiation generating portion with reference to the position of the subject so as to acquire a projection data set generated as the incident radiation is projected onto the subject; and a three-dimensional image processing portion for processing the projection data set and thereby restoring the three-dimensional internal shape image of the examined area, wherein the incident radiation is formed as a pattern that is proximate to the subject and is radiated from a radiating source positioned at a location spaced from the center position of the examined area toward the outer periphery, and the projection data set is acquired all at once. The present invention is advantageous in that neither the radiation source nor the subject rotates, and the detector acquires angle-specific projection data all at once and parallel-processes the same, thereby shortening the overall examination rate.
