8.15.5. mGy / mGy/min: (Active only on system manufactured after June 10, 2006)
During the exposure, the air Kerma rate display showing the current air Kerma rate in
mGy/min. appears on the control panel. Accumulated air Kerma readings of the fluoroscopy,
pulse fluoroscopy and radiographic exposure modes are displayed when ever the user releases
radiation.
8.16 LASER AIMING DEVICE
As an option, the system may be equipped with a laser targeting device at the image
intensifier and/or generator.
The laser targeting device uses diode laser modules which emit laser radiation. Do not
under any circumstances look directly at the laser beam or any scattered lase
radiation – either with the naked eye or with optical instruments.
The laser targeting device is a Class 2 laser product according to IEC 60825-1:2001.
and FDA 21 CFR, Subchapter J, Section 1040.10 - 11
NOTE:
The laser is a class II laser product, subject to 21 CFR Subchapter J, 1040. Its
peak power is <1 mW, and operates at a wavelength of 635 nm.
You must comply with all operating safety precautions when using the laser device. The
maximum output of continuous laser radiation, measured at the beam exit, is <1 mW. The
wavelength of the emitted radiation is 635 nm.
The laser Aiming device generates a laser-beam crosshair, the central point of which marks the
position of the central X-ray beam on the patient.
For safety, the laser targeting device is switched off automatically after 1 minute.
Laser Class II in accordance with FDA 21 CFR, Subchapter J, section 1040.10-11.
Please observe the provisions of IEC 60825-1:2001, Section 3, “Guidelines for the User” for
operation of the Laser Aiming device.
WARNING:
DO NOT stare into the laser beam! Eye damage may result! The use of optical
instruments with this product increases eye hazard.
8.16.1. RANGE OF APPLICATIONS
You can use the laser targeting device for the following tasks:
− As alignment aid for positioning the C-arm
− For foreign body localization −As a targeting aid for nail fixations
