In the case of image inspection, there is no need to develop the film, the photographed image can be viewed immediately, and image processing can be easily performed. However, since a 1゛V image can be displayed at 30 frames/Bac for 11 hours, when performing stereoscopic dynamic observation, conventional
The way it's being done, it's a good idea!
II image cannot be obtained. When performing 3D observation using TV images, conventionally, images taken with the left focus and images taken with the right focus were alternately displayed on a single TV monitor, and the images were synchronized with the display. By providing a switchable shutter, the left and right focal images can be viewed by the left or right eye respectively. This is because the information 1 that enters the eye of a single blade is 15 frames/soc, which causes flickering on the screen and a drop in the S/N ratio. The purpose of this invention is to provide a four-body X-ray imaging device that can obtain flicker-free, smooth three-dimensional dynamic images without increasing frame size.
