STEPPED SCANNER IMAGING SYSTEM

摘要

STEPPED SCANNER IMAGING SYSTEM An imaging system includes a radiographic camera, a bed for supporting a subject in view of the camera, and a display. The camera provides X and Y coordinate signals of each radiographic event. The position of the bed relative to the camera is altered sequentially between each of a sequence of images provided by the camera. The sequentially occurring images are presented on the display, each image being positioned on the display in correspondence with the location of the bed relative to the camera. The coordinates of each image point presented on the display is equal to the sum of the respective X and Y coordinate signals from the camera with X and Y coordinate signals defining the location of the bed relative to the camera. The camera is electronically decoupled from the display during a movement of the bed relative to the camera from one location to the next location to prevent a smearing effect and a zippering effect within a composite image presented on the display.
