摘要:
Roentgen-ray records of the heart and lungs lack in definition and in comparability, by reason of cardiovascular movement.A mechanism is described by which exposures may be made at any selected phase of the cardiac cycle.Systolic and diastolic cardiac outlines are reproducible at will.Pulmonary records can be made when cardiovascular movement is at the minimum.
