Electromagnetic Immunity
WARNING Power line anomalies or electrostatic discharges to the system may cause a CD
write failure error. A new CD should be used and the image re-written.
Radiation Safety
Always use the proper technical factors for each procedure to minimize X-ray exposure and to produce
the best diagnostic results. In particular, you must be thoroughly familiar with the safety precautions
before operating this system. Default techniques are designed to optimize the image processing param-
eters.
CAUTION There should be no people other than the patient in the room during x-ray expo-
sure. If circumstances require another person to enter the room while x-ray expo-
sures are planned or possible, that person should wear a lead apron in accordance
with accepted safety practices.
Radiation Protection
Because exposure to X-ray radiation may be damaging to health, use great care to provide protection
against exposure to the primary beam. Some of the effects of X-ray radiation are cumulative and may
extend over a period of months or years. The best safety rule for X-ray operator is “Avoid exposure to the
primary beam at all times”.
Any object in the path of the primary beam produces secondary (scattered) radiation. The intensity of the
secondary radiation is dependent upon the energy and intensity of the primary beam and the atomic
number for the object material struck by the primary beam. Secondary radiation may be of greater
intensity than that of the radiation reaching the film. Take protective measures to safeguard against it.
An effective protective measure is the use of lead shielding. To minimize dangerous exposure, use such
items as lead screens, lead impregnated gloves, aprons, thyroid collars, etc. The lead screen should
contain a minimum of 2.0 mm of lead or equivalent and personal protective devices (aprons, gloves, etc.)
must contain a minimum of 0.25 mm of lead or equivalent. For confirmation of the local requirements at
your site, please refer to your “Local Radiation Protection Rules” as provided by your Radiation Protection
Advisor.
