Improvements in technology permit tomographic radiographs to be taken at 1-mm intervals. Potter has matched four series of these tomograms with radiographs of actual 1mm cuts of the same brains, cut in coronal, lateral, axial, and oblique planes. Tomogram and section are placed on the left page, while a line drawing, with appropriate labels and description, are on the facing page. Additional text at the end of the book describes specific structures (orbit, optic canal, nasal and pterygopalatine fossae, and the temporal bone). The final chapter indicates which tomograms are best suited to solve problems such as those of orbital and paranasal sinus masses and trauma and problems of the ear.
Many structures evident in the sections are not recognizable in the tomograms because of "parasite shadows"; ie, superimposed blurred images of structures outside of the plane of focus. So many details are visible, however, that tomography has become indispensable
