Selection of imaging conditions in scintigraphy was evaluated using analytic hierarchy process. First, a method of the selection was led by determining at the points of image quality and imaging time, Influence of image quality was thought to depend on changes of system resolution, count density, image size, and image density. Also influence of imaging time was thought to depend on chnages of system sensitivity and data acquisition time.<BR>Phantom study was done for paired comparison of these selection factors, and relations of sample data and the factors, that is, Rollo phantom images were taken by changing count denisty, image size, and image density. Image quality were shown by calculating the score of visual evaluation that done by comparing of a pair of images in clearer cold lesion on the scintigrams. Imaging time was shown by relative values for changes of count density. However, system resolution and system sensitivity were constant in this study. Next, using these values analytic hierarchy process was adapted for this selection of imaging conditions.<BR>We conclude that this selection of imaging conditions can be analyzed quantitatively using analytic hierarchy process and this analysis develops theoretical consideration of imaging technique.
