The radiographic VOLTAGE is: 70kVp ±15% for “xgenus® ac” 60kVp – 70kVp ±10% for “xgenus® dc”

2. Radiographic current (mA)

The radiographic current is measured by connecting a milliampmeter. The mA value is factory checked with a digital multimeter.



The radiographic CURRENT is: 8mA ±15% for “xgenus® ac” 4mA – 8mA ±10% for “xgenus® dc”

3. Dose (mGy)

The dose in air is measured with a "non invasive" instrument, by positioning the detector at a spot-skin distance = 310mm (12”). The mGy are factory checked with the instrument SOLIDOSE.

11. CHECKING THE EXPOSURE FACTORS


4. Exposure time (s) The exposure time is measured with a “non invasive” instrument.

PLEASE NOTE∗∗∗∗∗∗∗∗ The “xgenus” x-ray control features the "self-compensating" technology. The automatic correction or compensation of the exposure time offsets the effects of the line voltage fluctuations on x-ray film quality. Radiographic over/under exposure is eliminated. The automatic correction system works as follows:

• A voltmeter located inside the timer constantly reads the mains voltage while the operator selects the required exposure time.

• The last voltage measured (before the exposure) is sent to the

microprocessor. The selected exposure time is corrected to voltage by applying a special algorithm.

• At the end of the exposure, during the pause time, the time-corrected value

is shown on the display of the x-ray control. THE PAUSE TIME IS APPROX. 32 TIMES THE SET TIME.

The correct time is the actual duration of the exposure

The accuracy of the “actual time” is factory checked with instrument PMX-I.



The EXPOSURE TIME measured is: 0.2s ±10% for “xgenus® ac” 1.6s ±10% for “xgenus® dc”

5. Checking the exposure time∗∗∗∗∗∗∗∗ (continued on p. 45: “Operating instructions”)

WARNING While performing periodic quality checks, some differences between the set exposure time and the measured exposure time may be detected. The differences are due to the automatic time compensation that intervenes when the power voltage differs from the nominal one.

The x-ray control is provided with two types of accuracy measurements for the exposure time:

A. Set exposure (is the exposure time set by the operator on the x-ray control).

The max error is +100% / - 100% when the voltage fluctuation is -5% / +10%.

B. After exposure: it’s the exposure duration (automatically adjusted). It’s calculated by the microprocessor according to the line voltage, and it’s shown on the display.

OPERATING INSTRUCTIONS:

CAUTION Radiations will be emitted.

To check the exposure times (sec) it is advisable to use calibrated “non invasive” instruments; i.e.:

NERO by Victoreen PMX by RTI TRIAD QA by Keithley

a. Put the “X-ray detector” at the cone outlet; center the primary beam. b. Turn on the x-ray control c. Set one exposure time on the control. d. Release the exposure. e. At the end of the exposure, when the functional pause period starts, read the actual time of

exposure on the display. f. To check the accuracy of the exposure time, use the chart below.

CONFORMITY CHECK CHART At the end of the exposure

1°

read the time value on the display = Actual exposure time

2°

read the measure on the instrument = Emission time measure

3°

subtract 1° from 2°

4°

divide 3° by 2° = Absolute error

5°

multiply 4° by 100 = Percentage error (%)

The accuracy is checked when the % of error is

±10% o ±20msec by adopting the most favorable condition.

PLEASE NOTE The exposure time complies with the requirements when:

((Measured time – Actual time) / Measured time)) x 100 ≤ ±10% or ±20 ms

Otherwise, please contact “Technical Support”.
