METHOD FOR APPLYING COMPUTER SUBTRACTION RADIOGRAPHY Russian patent published in 2003 - IPC

FIELD: medicine. SUBSTANCE: method involves building two initial X-ray pictures of an object under study in identical projections and producing the resulting image by processing spatial distribution of X-ray radiation reduction distribution in corresponding points of the first and the second initial X-ray picture of the object under study using computer software. One initial X-ray picture of the object under study is produced with X-ray radiation generation voltage being 1.1-1.3 times as large as the voltage used for producing the other initial X-ray picture. EFFECT: separated images of soft and hard tissues; higher accuracy of s diagnosis. 2 cl, 2 dwg
