A STUDY ON THE CROSS SECTION GRAPHY OF HUMAN BODY USING TOMOGRAPHY UNIT : with special refference to radiogram of the chest Report I

Abstract

It is the purpose of this paper to introduce a method of cross section graphy of human body, especially of the chest, using widely popularized tomography unit, which can be easily performed even in medical institution without rotatography unit. Patients were placed to be at right angeles to the movement plane of X-ray tube and the tube focus was setted diagonally to outward (10°-40°) and passed X-ray center through the cross section of the object and the center of X-ray film.
