Incident X-ray angles of weight bearing foot AP radiography which differ in each medical institution were compared. Optimal angles were derived from the study and suggested as basic data for clinical application. 19 patients with no abnormality on right foot took part in the study from June 2013 to July 2013. Weight bearing foot AP radiography in the correct position was examined with the incident X-ray angles of 10°, 15°, 20°, 25°, 30°, and 35°. All the images were evaluated subjectively by 5 radiological technologists of over 15 year work experience using Likert scale as 1 for ‘very poor’, 2 for ‘poor’, 3 for ‘fair’, 4 for ‘good’, 5 for ‘very good’, 6 for ‘excellent’, and analyzed with ANOVA and Scheffe. Image quality was the most optimal at 20°as 4.53, and relatively good at 25°as 4.38 and at 30°as 4.18. 35°and 10°were relatively poor. The average points of 6 groups indicated statistically significant difference (p<.01). In the post-mortem, 3 subgroups showed no statistically significant difference, and the average point of the groups of 20°, 25°, 30°was evaluated relatively higher than the other 2 groups. An optimal incident X-ray angle within the range from 20°to 30°for weight bearing foot AP radiography could make it possible to obtain the image of high diagnostic value and would be useful for clinical application in the future.
