Image analysis by on-line minicomputer for improved camera quality control.

The necessity for reasonable uniformity in the field response of a gamma camera is widely accepted(1-3). What constitutes "reasonable " uniformity and how to evaluate this parameter is far less certain (4-6). The usual method of visually inspecting an image of a flooded field for visible nonuniformity lacks sensitivity and precision. The use of minicom puters interfaced to cameras has been growing in popularity. As problems of comparison lend them selves well to computer analysis, it appeared that this would be a useful method of attacking the prob lem of quantitatively evaluating camera field uni formity.
