PROCESSING METHOD FOR THREE-DIMENSIONALLY RECONSTRUCTION OF OBJECT FROM SINGLE VIEW

摘要

PROBLEM TO BE SOLVED: To evaluate a refined orientation in a space for a basic object having a practically cylindrical rotation shape, while reducing irradiation on a patient.;SOLUTION: The orientation in a space for the basic object (10) having a practically cylindrical rotation shape is evaluated by: (a) a step to determine an X-ray dose A adsorbed by the basic object on a projection image; and (b) a step to evaluate the sine of an angle θ between a longitudinal axis of the basic object and a face of the projection image as a function of the absorbed X-ray dose A. An object formed of the basic object is reconstructed by (a) a step to determine the length of the basic object S_i and (b) a step to determine a spatial relative coordinate relating to P_i out of both ends (P_i-1 and P_i) of the basic object S_i on the basis of another end P_i-1.;COPYRIGHT: (C)2011,JPO&INPIT
