KaVo ProXam DIN6868-161/15 Tests Instructions for use

1 Introduction

In this manual, instructions for DIN 6868-161 and DIN 6868-15 based QA

(quality assurance) tests with the X-ray units are given.

These instructions are valid for KaVo ProXam 3D and 3D Q X-ray units.

NOTE

This manual is valid for the Device Tool QA software version 5.5.4 or later.

NOTE

For DIN 6868-15 Monthly QA tests, 3D Quart Test Phantom Set

(2.023.5072) is required and can be separately purchased from the X-ray

unit manufacturer.

For DIN 6868-161 Commissioning and DIN 6868-15 Yearly QA tests, it is

up to the customer to purchase the required two extra (top and bottom)

phantom blocks.

QA test types

There are separate set of QA tests for commissioning, for yearly and for

monthly QA tests.

•DIN 6868-161 Commissioning

DIN 6868-161 QA tests are carried out when commissioning the X-ray

unit. Tests include visual check, beam check, dose constancy and other

automated QA tests for several metrics.

The test results are saved to a acceptance data file, and when later

yearly/monthly QA tests are made those results are compared with the

metrics saved during the commissioning.

•DIN 6868-15 Yearly

DIN 6868-15 Yearly QA tests are carried out yearly. Tests include visual

check, beam check, dose constancy and other automated QA tests for

several metrics.

The test results are compared with the test results measured and saved

during the X-ray unit commissioning. If the metrics are inside or outside

of the tolerances, the QA test is either passed or failed.

•DIN 6868-15 Monthly

DIN 6868-15 Monthly QA tests are carried out monthly. Tests include

visual check and automated QA tests for a few metrics.

The test results are compared with the test results measured and saved

during the X-ray unit commissioning. If the metrics are inside or outside

of the tolerances, the QA test is either passed or failed.

From all of the QA tests, result summary is displayed and it is possible to

create a test report file to be archived.

In this document, instructions for all above mentioned QA tests are given.

6. In the appearing Quality Assurance - Beam Check window, measure the

collimation of the beam in each side of the sensor.

NOTE

Depending on the used X-ray ruler measurement tool, refer to the

manufacturer’s instructions, for more detailed instructions.

6.a. Attach the sensor of the X-ray ruler measurement device to the 1st

edge of the X-ray unit’s sensor’s cover plate.

In the X-ray unit sensor’s cover plate, there are auxiliary lines to

help the positioning of the measurement sensor.

When the capture is taken, the image is shown in the Beam Check

window. From the image you can verify the positioning of the

measurement sensor.

6.b. Once the sensor is in place, click Capture button for exposure to

be measured by the sensor.

Press the exposure button when instructed.

CAUTION

Radiation is generated when the exposure button is pressed. Take

adequate protection measures.

NOTE

If the above exposure is too weak to trigger the measurement

in the used X-ray ruler device sensor, you can use X-ray unit’s

test exposure function to have higher exposure parameters. In the

X-ray unit user interface, touch the service spanner button at the

top left corner of the main view, select 1500 Testing Routines -->

1510 Test Exposure and select suitable exposure parameters.

6.c. Check the reading of the measurement, and calculate accordingly

how much the beam is over the X-ray unit sensor’s active area

and fill the appropriate field with the value (in millimeters).

If the measurement shows a negative value, i.e. collimation makes

a shadow to the active area, the X-ray unit should be calibrated.

However, ensure first that the sensor has not moved during the

test and is in correctly placed in the X-ray unit’s sensor’s cover

plate.

6.d. Measure all other edges of the X-ray unit sensor in the same way.

6.e. When all 4 measurements are taken, click Next button.

7. In the appearing Quality Assurance - Dose Constancy window, measure

the dose from the center of the X-ray unit sensor.

NOTE

Depending on the used dose meter, refer to the manufacturer’s

instructions, for more detailed instructions.

7.a. Attach the dose meter sensor to the center of the X-ray unit’s

sensor’s cover plate.

In the X-ray unit sensor’s cover plate, there are auxiliary lines to

help the positioning of the measurement sensor.

7.b. Once the sensor is in place, click Capture button for exposure to

be measured by the sensor.

Press the exposure button when instructed.

CAUTION

Radiation is generated when the exposure button is pressed. Take

adequate protection measures.

7.c. Check the reading of the measurement and fill the 1st Dose field

with the value (mGy).

7.d. Do the measurement 3 times in the same way.

7.e. When all 3 measurements are taken, click Next button.

If this test fails, i.e. some of the measured value exceeds

too much from the calculated average value, repeat the whole

test once more. If the test fails again, the X-ray unit must be

investigated more carefully before taken into use again.
