Title:

MULTI-X-RAY PHOTOGRAPHY DEVICE AND CONTROL METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2010/032363

Kind Code:

A1

Abstract:

Disclosed is an X-ray photography device having: a multi-X-ray source that has multiple X-ray focal points that generate X-rays by irradiating X-ray targets with electron beams; a detector that detects X-rays that are emitted from the multi-X-ray source and reach a detection plane; and a movement mechanism that moves the multi-X-ray source within a plane that faces the detection plane. By moving the multi-X-ray source by means of the movement mechanism, the X-ray photography device emits X-rays from the multi-X-ray source while shifting the positions of the multiple X-ray focal points, which are possessed by the detector, relative to the detection plane, and thus multiple X-ray detection signals are obtained from the detector. Based on the multiple X-ray detection signals obtained from the detector, an X-ray photographic image is produced.
