The technologist will cover you from the waist down with a lead shield or apron. This shield protects your pelvic and reproductive organs from exposure to the radiation. The technologist also will position your body against the X-ray film in a way that produces the clearest image. In most cases, chest X-rays are taken from two positions: from back to front (called a posterior-anterior, or PA, view) and from the side (called a lateral view).
For the PA view, you will stand in front of the X-ray unit with your hands on your hips, your shoulders rolled forward and your chin lifted. The technologist will ask you to be very still and hold your breath while the X-rays are passed through your body. (This only takes a few seconds.) It is necessary to hold your breath because movement, which occurs when you breathe in and out, can blur the X-ray image.
For the lateral view, you will be asked to turn to the side, raise your arms over your head and lift up your chin. Again, you will be asked to be still and hold your breath while the exposure is made.
