Unger , M.D. VA Hospital 130 W. Kingsbridge Road Bronx 68, N. Y. Excerpt It is our purpose , in this paper, to describe our experience with transverse tomography for tumor diagnosis, tumor localization, and prognosis, as an aid to improvement of the surgical and radiation treatment of malignant disease. In cancer surgery, this third-dimensional method can help to establish the extent of local invasion, thereby permitting better evaluation of the operability and resectability of the malignant lesion. In radiation therapy, transverse tomography can also make a valuable contribution. It provides a “living” anatomical cross section of the patient as a sound basis for the development of an optimal therapy plan. It is generally agreed that upon the level of quality of this treatment plan depends, in large measure, the survival of the patient with radiocurable cancer, as well as the integrity of his vital normal structures. Our radiological colleagues in England, France, Italy, Germany, Japan, and Scandinavia have been describing for several years the advantages as well as the limitations of body-section radiography in the third or transverse dimension. They include Watson (18–20), Vallebona (16–17), Amisano (1), Gebauer (4–8), Stevenson (14), Frimann-Dahl (3), Takahashi (15), and Frain (2). In this country, however, less than a dozen radiologic departments have yet shown interest in this approach to roentgen anatomy, diagnosis, and therapy. Indeed, only one report has been published by an American author (Wilk, 21) in addition to our own (12). Perhaps some of the European workers have placed entirely too much emphasis on the early frustrating technical problems, of which we have had our fair share. Today, however, transverse tomograms can be made with the same ease, quality, and reproducibility as conventional body-section radiographs in the sagittal and coronal planes. Technical Factors In theory, the principle of transverse tomography is relatively simple. The erect patient and the horizontal cassette, on two separate stands, are rotated simultaneously through 360° in the same direction and at the same speed by the same motor drive during the x-ray exposure. The x-ray tube remains stationary, directed downward at an angle of 25° toward the film. The points of all structures in the selected plane of the patient remain co-linear with identical points on the film, producing sharp, stationary images. The points of all structures situated above or below the selected plane cast only moving shadows on or off the film and are therefore blurred or not even reproduced (Fig. 6, C). In our practice, the technic of transverse tomography has now become a fairly routine matter, but it was not always so. At the outset of our investigation, nearly five years ago, we constructed our own equipment, based upon data published by Vallebona, Amisano, Watson, Gebauer, and others in the European literature. Later we acquired a commercially available apparatus.
