Title:
X-RAY IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/116494
Kind Code:
A1
Abstract:
Disclosed is an X-ray imaging device with which X-ray exposure will not be stopped by the backup time, causing underexposure, in phototimer imaging, because the body of the subject is thick. A database unit (18) stores a database showing the relationships between a variety of subject (M) body thicknesses (t), X-ray parameters, and imaging times. A search processor (16) searches the aforementioned database for data matching X-ray parameters stored in a parameter storage unit (15) and body thicknesses (t) calculated by a body thickness measurement unit (17), and requests the corresponding imaging time. If the imaging time is longer than the backup time set by an X-ray controller (12), the search processor (16) instructs the X-ray controller (12) to extend the backup time to the imaging time. The X-ray controller (12) extends the backup time, X-ray exposure is performed by a high-voltage device (13) according to the X-ray parameters stored in the parameter storage unit (15), X-ray exposure is stopped when an X-ray shutoff signal is received by the phototimer (11), and imaging is ended.
