Abstract: 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.

Abstract: The present invention relates to an image heating apparatus that includes a heater including a plurality of independently controllable heating blocks in a longitudinal direction thereof, each including a first conductor, a second conductor, and a heating element. At least one of electrodes corresponding to the respective heating blocks is disposed in an area where the heating element is located in the longitudinal direction on a second surface of the heater that is opposite to a first surface that comes into contact with an endless belt. An electrical contact is arranged so as to face the second surface of the heater. An overheating occurring in a no-media passage portion when an image formed on a recording material having a small size is heated is suppressed or reduced.
