PROCESSING METHOD OF DATA ACQUIRED FROM CT SCAN

摘要

PROBLEM TO BE SOLVED: To provide a method and a program for an improved multislice X-ray computed tomography system which uses the weight dependent on a detector row to cone-beam backprojection with general weight. SOLUTION: In the processing method of data acquired from CT scan, OS weight is calculated to at least one direct ray and two or more complementary rays. The weight dependent on a row is calculated based on the cone angle of the detector row. The OS weight is corrected based on the weight dependent on a row. Normalized weight is calculated and is used for backprojection. COPYRIGHT: (C)2011,JPO&INPIT
