Roentgen kymography has been accepted as a diagnostic method in the clinical study of heart disease. The procedure was later applied to the study of the peristaltic movements of the stomach, duodenum, small intestine and colon by Stumpf, Weber and Weltz,1 Schilling,1a Dahm2 and Weltz.3 Our purpose in this paper is to report and in general to confirm their observations. In doing this we have borrowed freely from their publications and personal communications.The principles and technic of roentgen kymography must be clearly understood in order to interpret the films, or kymograms, as they are called. The multiple slit kymograph is the achievement of Pleikart Stumpf, who introduced it in 19284 and perfected it by 1931.5 The apparatus is relatively simple and commercially available (fig. 1). The essential part is the grid, which is made of a large sheet of lead one-sixteenth inch thick. |
