5.6 Verification method of technical factors
(paragraph for authorised personnel)
The exposure parameters (kV, time and dose) can be checked using the
so-called "non-invasive method".
WARNING:
The device collimator gives a narrow X-ray beam.
Measurements taken with a non-invasive instrument and a narrow beam
can be difficult and/or unreliable; it is therefore necessary to use a
special probe with a reduced sensitive area.
It may be helpful to use a fluorescent screen to locate the X-ray beam,
and consequently position the probe of the kV meter.
The procedure to measure the exposure parameters by a non-invasive kV
meter is the following:
1. With the unit switched ON, be either in Anatomic or Manual mode,
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 variation due to spine compensation.
2. Place the measuring instrument.
