- W2049440123 abstract "In Anger camera imaging, probably the most important parameter of camera performance is field uniformity. For the majority of camera users, field uniformity is evaluated in a subjective manner by simply viewing polaroid field floods. Due to film lim-itations, viewing conditions and statistical limitations, it is questionable if count density differences less than 15-20% can really be identified. To shift from a qualitative to quantitative method of field uniformity determination, a photographic method using high count density 70mm images has been developed. For the majority of Nuclear Medical imaging procedures, the current instrument of choice is the Anger camera. Of the An camera performance parameters, probably the most important is field uniformity. For those few institutions with dedicated computers interfaced to an Anger camera, field uniformity can be assessed and even corrected by the computer. However, for the majority of camera users, no quantitative method of uniformity evaluation exists. To shift from a qualitative to quantitative method of field uniformity determination without an interfaced dedicated computer, a phogographic method using high count density 70mm images has been developed; similar to film isodore methods in radiation therapy." @default.
