Image Distortion in Rotational Panoramic Radiography
Gunilla Tronje, U Welander, William D. McDavid, CHARLES R. MORRIS · Acta Radiologica Diagnosis · 1981
Mathematical calculations have been performed to analyse how accurately the angle between objects, inclined in space, is reproduced on panoramic films. A marked tolerance against angle distortion was found. Angular measurements may be performed on correctly exposed panoramic films, and the values obtained are satisfactorily accurate for most clinical purposes.
