Medical institutions usually find it difficult to select computed radiography (CR) equipment because of the involvement of many complicated factors such as operability, processing time, and price. The analytic hierarchy process (AHP) is often applied in complex decision and evaluation situations. This study quantitatively evaluates the institution’s selection criteria of equipment using AHP. The AHP model of this study consisted of 3 levels: the goal, 6 evaluations, and 3 alternatives. Processing time, price operability, picture quality, connectivity, and equipment size were considered as the criteria for decision marking. We simulated alteration of priority of evaluations by changing the weight of pricing between 0 and 1. Results showed that price and connectivity accounted for 60% of the total weight. On excluding operability, the difference in weight between equipment was 1.16 times; the priority of processing time was 1.36 times; and the priority of price was 1.37 times. In the same way, when considering operability, the difference in weight between equipment was 0.36 times, the priority of processing time was 0.45 times, and the priority of price was 0.11 times.
