By fluoroscopy it is possible to obtain a fairly accurate outlineof the shape and position of the heart shadow and of its movementswith respiration; also of any change of shape which may occur withchange of position. By combining this data with the data obtainedfrom a plate taken at a seven-foot target film distance, all therequired findings are present. This method of combined fluoros
