Research output: Contribution to journalArticlepeer-review


The position and form of the image layer in rotational panoramic radiography vary from one manufacturer to another. A method utilizing a digital computer to calculate the position, form, and relative thickness of the image layer from data obtained from two test radiographs is described. The image layer analysis permits the performance of different rotational panoramic radiographic units to be compared independent of various parameters such as beam width and magnification. The image layers for several commercially available units are illustrated.
