Abstract: An investigation of the image quality of 5 panoramic X-ray units was carried out for this paper. Measurement of the MTF clearly shows good resolution for the Art Plus unit (MTF(50%) = 5.61 lp / mm) compared to the average of all 5 of the units (3.44 ± 1.55 lp /mm). To investigate image noise, the ratio was calculated between average gray scale value and standard deviation in a 32 × 32 matrix (R32x32). Compared to the other units, identical regions in the image are less noisy for the Art Plus unit (32x32 R = 92.28 and 32x32 R = 19.40 ± 11.00 for the other units). Also image displacement of a series of images was determined for the Art Plus and the Pro Max unit. The displacements were between 1-5 Pixels for both.
