Title:
X線断層撮影装置
Document Type and Number:
Japanese Patent JP4054402
Kind Code:
B2
Abstract:
An X-ray tomosynthesis system as an X-ray diagnostic system is provided. The system comprises an X-ray generator irradiating an X-ray toward a subject, and a planar-type X-ray detector detecting the X-ray passing through the subject and outputting two dimensional imaging signals based on the detected X-ray. The system comprises a supporting/moving mechanism supporting at least one of the X-ray generator and the X-ray detector so that the at least one is moved relatively to the subject. The system also comprises an element setting a ROI position of the subject, an element for obtaining a plurality of three dimensional coordinates of pixels included in the ROI, a calculating element obtaining two dimensional coordinates of data in the two dimensional imaging signals for each of the two dimensional imaging signals detected by the X-ray detector, the data being necessary for obtaining pixel values of the three dimensional coordinates; and an element for obtaining the pixel value of each of the three dimensional coordinates by extracting the corresponding data of the two dimensional coordinates from the detected two dimensional imaging signals and adding the extracting data.
