Abstract
Official abstract text for this publication.
An X-ray detector ( 320 ), configured to have X-ray detecting elements ( 322 ) arranged in array, detects the intensity of X-rays that are radiated from the X-ray tube ( 311 ) and have passed through a subject ( 500 ). A data processing device ( 420 ) executes steps of: arranging scan data, which is based on the intensity of X-rays, in an array sequence of the X-ray detecting elements ( 322 ) or in a time sequence, to detect an anomalous scan data; associating a weight greater than “1” with scan data adjacent to the anomalous scan data, and associating a weight of “1” with other imaging data; calculating an update amount of a pixel vector that reflects these weights; and performing an iterative operation using the update amount to generate an X-ray CT image of the subject ( 500 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. An X-ray CT apparatus comprising: an X-ray generator that generates X-rays; an X-ray detector that is configured to have multiple X-ray detecting elements arranged in array for detecting intensity of the X-rays; a scanning control unit that transmits detection data detected by the X-ray detecting elements as scan data of a subject; and a data processing device that obtains the scan data transmitted from the scanning control unit, and processes th…
