Title: Method for data correction and x-ray ct apparatus
Inventor: NUKUI MASAYASU
IPC: A61B6/03
Filed: 2002-09-13
Abstract: <P>PROBLEM TO BE SOLVED: To correct data by distinguishing abnormal discharge (spits) occurring in an X-ray tube from incidence disturbance (ref. obstruction) of an X-ray to the reference channel of a detector.  <P>SOLUTION: The method for data correction monitors reference channel data Ref_j and tube voltage kVj by an X-ray CT apparatus. When lowering in the reference channel data Refj and lowering in the tube voltage kVj are detected and when lowering in the reference channel data Refj is detected and its former time is the state of abnormal state, the method determines the cases to be abnormal discharge. When lowering in tube current is not detected in spite of detecting lowering in the channel data and the former time is not the state of abnormal, the method determines the case to be reference channel obstruction (P1 and P2). In the case of determining the case as reference channel obstruction, the method never performs abnormal discharge correction (P4). Thus, the method avoids wrongly performing unnecessary abnormal discharge correction in the case of the incidence obstruction of the X-ray on a reference channel.  <P>COPYRIGHT: (C)2004,JPO
