<p><P>PROBLEM TO BE SOLVED: To minimize a movement of a patient and a detector artifact, and to read the detector with high speed without damaging a picture quality by minimizing the testing period. <P>SOLUTION: A method of minimizing the artifact of a double-energy image or a multiple-energy image includes processes (406, 412) of obtaining a first and a second offset images from a detector (110) after obtaining a first and a second exposure images from the detector (110). In other embodiments, dosage of exposure is changed, gain of the detector (110) is changed (408), a pixel acquisition resolution of the detector (110) is changed (408), and the detector (110) is not scrubbed between a first read time (406) and a second read time (412). <P>COPYRIGHT: (C)2004,JPO</p> |
