This paper reports the development of a unique computer-controlled LLTV camera. The camera was developed specifically to meet the rigorous requirements imposed by computer tomography, computerized video processing for image recognition, and industrial X-ray inspection systems. The first large-scale application of the new camera is by researchers at the Mayo Foundation as a key component of the Dynamic Spatial Reconstructor (DSR) Program. The DSR is a medical diagnostic tool which will be capable of acquiring up to 28 X-ray images every 1/60th of a second. These images are processed by computer reconstruction algorithms to produce three-dimensional radiographic images of moving organs--images which would be unattainable with existing X-ray procedures. The camera features several unique capabilities which facilitate image acquisition and image quality. Examples of these are high-speed photocathode gating, a triggered scanning mode which holds the scanning electronics in areset condition until an image is acquired and a scan-initiate command is received from the computer, 0.25 percent absolute geometrical accuracy at any point on the scanned image, the capability to correct distortions introduced by optics or image intensifiers, and a standby mode which enables the system to be quickly powered up for intermittent duty operation.
