Publication number: 20240144555Abstract: To reduce an unnatural distortion of an image that occurs in a case in which a high absorption body of X-rays is included in movement correction image reconstruction processing of a CT image. High absorption body presence or absence determination processing of determining whether or not a high absorption body of X-rays is included is added to movement correction image reconstruction processing, and processing of limiting pixel values of an image pair used for movement correction or processing of selecting an image pair used for calculating a movement vector is performed based on a result of the determination. An X-ray CT apparatus includes a high absorption body determination unit or a pixel value adjustment unit to perform these pieces of processing.Type: ApplicationFiled: October 19, 2023Publication date: May 2, 2024Applicant: FUJIFILM Healthcare CorporationInventors: Yoshiki MORI, Yuta OGURA, Ryota KOHARA, Yusuke TETSUMURA
