Summary
In this report, basic principles of panoramic tomography are suggested. According to this principle, the effective rotation center doesn't have the importance as was considered before, the tomographic factor of panoramic tomography and the scanographic factor of panoramic tomography are clearly separated, and the relationship between these two factors are mentioned. Exposure angle and section thickness are related to the tomographc factor, and projection angles and image distortion and characteristics of formation of superimposed blurred structures are related to the scanographic factor.
There are no machines satisfying the new principle, but the new panoramic tomograph can be designed according to and as an extension of this new principle.
