Title:
METHOD FOR CORRECTING PROJECTION DATA, METHOD FOR GENERATING IMAGE AND X-RAY COMPUTER TOMOGRAPHY
Document Type and Number:
Japanese Patent JP2004065706
Kind Code:
A
Abstract:
To form a normal computer tomographic image as compared with a prior art even when a subject protrudes outside of an end channel of a detector.
When the subject protrudes outside of the end channel (1), the projection data (da) of the outside of the end channel (1) is formed based on the projection data (dn) of the channel near the end, and a computer tomographic image is generated based on this corrected projection data. Thus, the computer tomographic image of the field of view larger than the actual field of view can be formed.
