Electronic Grids for Electrostatic Imaging Systems

Abstract: Electronic grids have been substituted for conventional grids in an electrostatic imaging system and have been useful in chest radiography. Electronic grids also appear to be useful for clean-up of small amounts of scattered radiation in radiographs of the extremities. More clinical work is needed before a statement about the use of electronic grids for other examinations can be made.

“…16 Muntz et al 63 developed a scatter point-source model to describe the dependence of scatter-toprimary ratio (SPR) on system geometry. The model assumes scatter to originate from a virtual point source located at distance y scat from the object plane (isocenter), typically in the direction of the primary x-ray source.…”

“…To determine the appropriate air gap distance for the back detector, selectivity was calculated using the 'effective scatter source model suggested by Muntz, et al [23] and developed by Sorenson and Floch [18]. According to this model, scatter radiation behaves as if it originates from a point source located between the focal spot and the exit surface of the object.…”
