With the current active interest in "noninvasive" cardiac diagnostic techniques, this procedure might have fallen into a place of great importance, but has not. My goal, in addition to assessing the book, was to try and understand why this might be.

The discussion begins with a survey of the history of roentgenkymography. This is followed by a description of the method. As a forerunner of motion recording techniques in roentgenography, the method provides a picture of x-ray dense shadows over two or three cardiac cycles, with moving borders presenting a serrated appearance on the film. The depth of the serrations indicates the extent of motion, if the border is oriented perpendicular to the direction of travel of the x-ray grid.

The text is largely dedicated to areas of interest to the
