Abstract：
:The purpose of this paper is to present the possible usefulness of macrotomography with three-fold magnification as demonstrated by a new apparatus. It can perform both conventional tomography and macrotomography of the same object plane. Quantitative evaluation included measurements of resolution, modulation transfer function and radiation dose. Qualitative evaluation included an analysis of clinical cases in which both techniques were used. The superior image quality of macrotomography with three-fold magnification was demonstrated and the clinical areas in which it proved most helpful are defined.
