    Notes: 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.

    Monte carlo calculations of mean bone marrow dose and energy imparted from CT head scanner (1989)
    Springer
    Oral radiology 5 (1989), S. 39-45

    Notes: Abstract Because of the potential for high radiation doses in CT procedures, the object of this study was to estimate the mean bone marrow dose and the energy imparted from a 3rd generation CT head scanning procedure using Monte Carlo simulation. The simulated and calculated mean bone marrow dose (μGy) and energy imparted (mJ) per 1cm slice thickness scan are as follows: Adult 120kV,effective mAs 553mAs Child 120kV, effective mAs 213mAs 173-376μGy, 16.0-18.3mJ (Western) 67-136μGy, 5.5-6.5mJ (Western) 110-208μGy, 16.0-18.3mJ (Japanese) 64-120μGy, 5.5-6.5mJ (Japanese)
