Quick Check
Calibration for the external probe
You can select between Normal, Timed or Free run
Normal =use this measuring mode for exposures and fluoroscopy
Timed = meter measures during a time you specify
Free run = meter measures continuously without use of any trig levels
(for more information see table below)
Measurement
time
(Timed mode only)
Measuring time when Timed mode is used.
Select the waveform recording time. Use the shortest time to see details in the
waveform. If you use a longer time, you lose details in the waveform. This setting
doesn't influence on the accuracy.
This is the waveform type for the X-ray generator. It is normally HF/DC. Sometimes
for older X-ray units and for dental you must use 1-phase. Be careful to select the
correct waveform type for maximum accuracy. Note that there is a special selection for
AMX-4.
Total filtration
(External)
(R/F, dental only)
The filtration used the external RTI Dose Probe to do energy compensation.
Added filtration
(mammography
only)
Added filtration used for the internal detector do do energy compensation and kV
compensation.
Added filtration
(External)
(mammography
only)
Added filtration used for the external RTI Dose Probe do do energy compensation.
Compression
paddle
(mammography
only)
Select here if compression paddle is used or not used.
Compression
paddle
thickness(mm)
(mammography
only)
Specifies the thickness of the compression paddle in equivalent mm Al. Default is 0.12
mm.
This is the level used for the time measurement. You can use this if you want for
example to avoid pre-pulses to be included in the exposure time.
Normalized
exposure and
exposure rate
The square-law is used to normalize the dose and dose rate to a distance (SSD)
different from the measuring distance (SDD) when the box is checked.
How to use the different calibrations:
General radiography, fluoroscopy, dental and CT
