The angle of right anterior oblique radiography of the heart is

The right anterior oblique photography angle of the heart is 45 ~ 55 degrees.

Precautions for cardiac photography are as follows:

1. High kV, high mA and short exposure time are suitable for cardiac photography to reduce the influence of breathing and heartbeat on image clarity.

1. Focus on the distance of 180 cm ~ 200 cm to reduce the magnification distortion of the image.

3. After inhaling deeply, hold your breath and expose it, so that the diaphragm will drop and the overlap between the heart shadow and the diaphragm will be reduced. Be sure to do a good job of breathing control training before shooting.

4. Barium should be swallowed in the right anterior oblique position to observe the relationship between esophagus and cardiac blood vessels; Lateral photography should take the left position.

Projection techniques and methods are as follows:

1. The focal distance is180cm to 200cm.

The midline is aimed at the sixth thoracic vertebra, and the film is taken vertically.

3. Ask the patient to take a deep breath and then hold his breath for exposure.

3. Before the right front oblique exposure, let the patient swallow a mouthful of barium first, and then swallow a mouthful of barium. After swallowing the second barium dose, take a deep breath and hold your breath for exposure.
