5.3 Patient Positioning
 Have patience (especially pregnant women and children)
wear a lead apron to protect themselves from residual
radiation.
 Be careful not to shine the laser beam directly into the
person's eyes. Doing so may result in vision loss.
 Correct posture reduces the shadow cast by the patient's
cervical spine and allows clear image acquisition.
 Metal implants or bridges may reduce the quality of the
images.
 Be sure to adjust the laser beam correctly. Otherwise,
the quality of images can be lower due to ghost images
or expansion/reduction of the images.
There is a horizontal beam laser for the guide that points the
patient's shoulder in the rotator section. This laser allows
you to proactively identify the possibility of moving the
rotator and touching the patient's shoulder. If the laser is
pointing at the patient's shoulder, it can be lowered further to
prevent the rotator from touching the patient's shoulder.
