Getting Prepared for Patient Positioning

62
Have patients (especially pregnant women and children) wear a

lead apron to protect themselves from residual radiation.
Be careful not to direct the Laser Beam into the patient's eyes.

Doing so may result in a permanent loss of vision.
When the equipment is not operable while the Rotating Unit is in
operation or in exposure location, bring the patient out of the
equipment immediately as follows.
[When the patient is biting the Bite Block ] Ask the patient
①
to open the mouth.
Ask the patient to back off a bit.
②
[When the Headrest is attached] Detach it. (The operator
③
or the patient must keep holding the Headrest until the
Handle Frame is opened and take it out after the Handle
Frame is opened.)
[When the Chinrest Ass'y is attached] Take out the
④
Chinrest and the Chinrest Base in turn separately.
Open the Handle Frame.
⑤
Guide the patient out of the equipment.
⑥
* For ①, ③ and ⑤, each step can be skipped if it's not necessory
according to the existence of each accessory.
Correct posture reduces the shadow casted 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 Laser Beam correctly. Otherwise, the quality of

images can be lower due to ghost images or expansion / reduction
of the images.
To minimize the time that the patient spending inside the equipment, it
is highly recommended to complete configuring exposure parameters
first before to start positioning the patient's posture.
