Title:
校正手段を持つC-アームX線装置
Document Type and Number:
Japanese Patent JP2006509554
Kind Code:
A
Abstract:
The invention relates to an X-ray apparatus having a C-arm assembly ( 1 ) on which an X-ray source ( 4 ) and an X-ray detector ( 5 ) are arranged opposite one another, the C-arm assembly ( 1 ) being arranged to be rotatable about a propeller axis ( 9 ) and an axis of rotation ( 11 ). To enable calibration to take place even on-line during the acquisition of projected data, respective marker arrangements ( 14, 15 ) are mounted on the X-ray source ( 4 ) and the X-ray detector ( 5 ), and a camera arrangement ( 12 ) for detecting the marker arrangements ( 14, 15 ) is arranged on the C-arm assembly ( 1 ) to allow the positions of the X-ray source ( 4 ) and the X-ray detector ( 5 ) to be determined. With this arrangement, the problem of the blocking of lines of sight between the marker arrangements ( 14, 15 ) and the camera arrangement ( 12 ) is reduced or completely avoided.
