4.4. Verification method of exposure parameters
The exposure parameters (kV, time and dose) can also be verified using
the so called "non-invasive method".
WARNING:
The machine collimator gives a narrow X-ray beam.
Measurement by a non invasive kV meter on a very narrow beam can be
difficult and/or unreliable and special probes with reduced sensitive area
must be used.
It may result helpful to use a fluorescent screen to locate the X-ray beam
and consequently position the probe of the kV meter.
The exposure parameters can be checked with a non-invasive instrument
by performing the following procedure:
1. With the unit switched on, be either in Anatomic or Manual mode,
2. press the "Anatomic/Manual" mode indicator until it turns green and
displays "S" , then press the "Test function" (5)
key to enter the exposure verification mode, the display shows:
x x k V x x m A x x . x s
E M I S S I O N P R O G R A M
WARNING:
The following operations involve the emission of X-rays, so the
Authorised Technician must pay the greatest attention and respect the
protection regulations in force in that country.
NOTE:
This program allows you to carry out the measuring of the exposure
parameters with the tube-head arm in a fixed position (not rotating)
without variations due to spine compensation.
3. Place the measuring instrument.
