Title:
X-RAY IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/017058
Kind Code:
A1
Abstract:
According to the present invention, motion blur can be suppressed by controlling so that the pulse width t of X-ray exposure decreases as the relative velocity of a top plate with respect to an imaging system increases during a series of imaging operations. Also, control is performed so that even if the pulse width t decreases, a tube current value I increases by a corresponding amount. If controlling to increase the tube current value I is not possible due to the rating of an X-ray tube, the suppression of motion blur is prioritized over a certain amount of decrease in radiation dose. Conversely, when motion blur does not occur at all due to the slow relative velocity of the top plate, the necessary radiation dose can be obtained by controlling so that the tube current value I decreases by as much as the pulse width t of the X-ray exposure increases.
