Product description

5 OperationThe X-ray sensor is connected to the computer via the sensor cable� The sensor is placed and activated via an imag-ing software (e� g� D-Tect)� During the X-ray procedure, the x-rays are re-ceived by the scintillator (luminescent material) installed on the sensor and are converted into beams of light� These light beams are recorded by the sensor as image information, digitalised and transferred to the computer� If an error oc-curs during the transfer, the image information is sent again� No further X-ray image is possible during data transmission�

The acquisition modes listed are standard con-figurations� The acquisition modes can be adapted, depending on requirements and appli-cation�Depending on the X-ray source and the record-ing conditions, the basis spatial resolution can change�

10.1 Taking an X-ray imageX-ray images with the DR 7 NDT are generated using multiple integration� Multiple integration produces a low SNR (signal to noise ratio)�Check before every use:

– The sensor and cable are not damaged� – The sensor and cable have been cleaned�

NOTICESensor damage and deterioration of the image quality resulting from high exposure values in the free beam path i With exposure values > 70 kV, protect the sensor accordingly�

i Comply with the maximum total dos-age of 20 Gy�

i Place the sensor� i Start the computer� i Start the imaging software� i Select the project� i Change to X-ray module� i Select the desired acquisition mode�

10 Operation

NOTICEDamage to the sensorThe interior parts of the sensor can be damaged by mechanical forces� i Do not drop the sensor� i Do not subject the sensor to any pressure�

i Do not fold, clamp or crush the cable� i Do not carry the sensor by the cable�

CAUTIONA damaged sensor can result in the issue of materials which damage health i Check the sensor and cable for dam-age before every use�

i Do not use a damaged sensor�

NOTICEShort circuit due to the build up of condensationStrong temperature fluctuations can damage the unit� i Only commission the unit once it has warmed up to room temperature�

i Do not subject the unit to strong tem-perature differences (heating max� 3 °C/min)� Exception: short-term use of the sensor at a temperature of up to 45 °C� This could produced in-creased levels of inherent noise in the image�

If DR 7 NDT is operated with D-Tect, you can generate X-ray images in the following acquisi-tion modes:

– NDT high (19 µm) – NDT Standard (19 µm) – NDT fast/binning (38 µm)

The transmission time takes a few seconds de-pending on the setting�

Operation

i Trigger the X-ray image with Start integration�

The image is automatically transferred to the imaging software� No further X-ray image is possible during data transmission�

Perform offset-gain calibrationThe offset-gain calibration minimizes the falsifi-cation of the image information (e� g� through an inhomogeneous illumination of the X-ray source)� The offset-gain calibration is performed in two steps:

1� Sensor calibration without an active X-ray source (offset)

2� Gain calibration of the sensor with an active X-ray source without objects in the beam path (Gain)

i Click � i Working in the Calibration range, select Off-set-Gain from the selection list�

Under Status:Idling is displayed�

i Click the Scan button�

The Image acquisition window opens�

If an acquisition mode is used for the first time, or if this has been changed, offset-gain calibration must first be performed (see "Perform offset-gain calibration")�

i Click �
