clothing must be worn.
4.1 Calibration of the option Integrated Dose Measurement Device 2
A calibration of the optional installed Integrated dose measurement device
(air kerma measurement device or area dose product measurement device)
is not necessary.
4.2 Information about air kerma strength determination 2
The air kerma strength is determined with a measuring chamber integrated into the sys-
tem. The reference location for determining the air kerma strength is 30 cm in front of the
image intensifier input (70cm distance from the focal spot).

All local safety regulations must be observed.
Checks or adjustments to be performed with radiation ON are
marked with the radiation warning symbol .
This value is used because in typical applications the object to be
examined is located approx. 30cm in front of the I.I.

Function tests 5
1 Checking the accuracy of the tube voltage 5
The actual kV value must agree with the indicated value within the limits stated by
Siemens (max. deviation &10 % for the ARCADIS Avantic), if the X-ray system is con-
nected to a power supply corresponding to Siemens specifications.
Tools: PTW-Nomex
Test procedure:
Refer to the information on the Nomex in the operating instructions
Connect the Nomex.
Remove the single-tank cap at the POWERPHOS after removing the two screws.
Select full image intensifier format and open the collimator fully.
Place the measuring detector on the diaphragm.
Set the following values in the operating field and check
2 Reproducibility 5
The coefficient of variation must not exceed 0.05 when the X-ray system is connected to a
power supply as specified by Siemens.
The technique factors should be adjusted to alternate settings and reset to the test setting
after each measurement.
2.1 Measurement set-up 5
Place the dosimeter in the center of the X-ray beam.
Before each new dose measurement, make sure that the indicator is reset to zero.
Operating mode Indicated Measured Tolerance

2.2 Calculations 5
Variation coefficient C
For n individual measurements, the coefficient of variation C amounts to:
s = calculated standard deviation
= mean value of all individual measurements
xi= measured value of the ith measurements.
1. To obtain the average x, the 4 dose values are added and the sum is divided by 4.
2. To obtain the difference, the average value is subtracted from each individual
measured value and entered into the column provided
Square the differences
3. Add the 4results: Σ....................:
4. Divide the sum by 4: ...............
5. Obtain the square root of the new result: Square root S: ..................

3 Entrance dose rate 5
The legal maximum entrance dose rate is 87 mGy/min (10 R/min).
For safety reasons, the value has been fixed at < 78 mGy/min (9 R/min) at the factory.
The entrance dose rate imust be checked by means of a dose rate meter.
In the measurement setup shown, the maximum adjustable value of 125 kV yields an
input dose rate of approx. 87mGy/min (10 R/min).
Measurement set-up
Position the measurement detector of the dosimeter as shown in the diagram.
Press the " ” button at the operating console.
Select 125 kV. Select full I.I. format, open the collimator to max. aperture, switch fluoros-
copy ”ON”. Measure the dose and record.

The smallest field size should be < 5 cm x 5 cm at the I.I. input.
The check is made at the TV monitor.
1. Select full I.I. view format.
2. Close the iris diaphragm and select full I.I. view format.
3. Attach a center cross with lead ruler to the center of the I.I. input screen.

6 Checking the field limitation 5
REGULATION -
Fluoroscopy and radiography using the fluoroscopic imaging assembly with inherently
circular image receptors.
When any linear dimension of the visible area of the image receptor measured through
the center of the visible area is less than or equal to 34 cm in any direction, at least 80
percent of the area of the x-ray field overlaps the visible area of the image receptor.
The check is made at the TV monitor.
Determine the central point at the I.I. input. Use adhesive tape to attach center cross
(with lead ruler).
Open the slot collimator, adjust the iris diaphragm to an opening of about 15 cm.
Perform the test in the C-arm position shown.
