X-Ray Imaging with a Scanning Beam

Abstract: An x-ray imaging system that makes use of a rapidly scanning pencil beam of x rays to acquire images of any part of the body has been developed. The system is capable of generating and displaying images in 15 seconds, using extremely low radiation exposures. The principle of its operation, its unique imaging properties, and its possible applications are discussed.

“…The output from the diodes in each array are summed in groups of six prior to digitization, reducing the area to be imaged at one time, hence the alternative name of area systems (11). The scanning methods, on the other hand, record the image sequentially either point by point (13,14), or line by line scanning single or multiple lines at one time (l, 6).…”

“…a collimated fan beam of x-rays and a rapidly spinning metal disk containing radial slits ( 2 ). This approach, sometimes called a fl ying spot, has been used in several clinically oriented imaging systems ( 50,51 ). Of issue here is the potential reliability of a rapidly rotating mechanical chopper-wheel system.…”
