7. Functional layout

8. Functional Description The system is supplied with power by a power unit (5) (green LED (9a) illuminated). The 3 m long cable from the CCD sensor (2) is inserted in the CCU controller (1). The CCU controller is connectedwithafreeUSBinterfaceonthePC(3)viaaUSBcable(4).The CCD sensor is provided with and positioned with a hygienic protective cover. Imaging ca-pabilities of DR 6 must then be activated in the x-ray software. This is indicated by the yellow LED (9c).

WithX-rays,thex-raysareconvertedtobeamsof light by the scintillator (luminescent material) applied on the CCD sensor.The image information is the digitalised, saved in the CCU controller and then transferred to the PC. If an error occurs during the process, the image information is sent again. During the data transmission, no further capturing is possible.

9. Set-up 9.1 Room for set-up

Danger of short circuit due to build up of condensation. The system can only be put into operation once the appliance has warmed up to room temperature.Do not subject the CCD sensor to major temperature differences (hea-ting max. 3°C/min). Exception: Standard heating from room temperature approximately 20°C to body temperature approxi-mately 37°C during the application.

•Donotsubjectthesystemtodirectsunlightor heat. Utilise only in a room that is designed respectively (e.g. x-ray room). Do not use in the open.

•Theroomforset-upisnottocontainanymajor interference fields (e.g. strong magnetic fields), this could lead to faults in the device.

11.2 Installing the calibration software

Each CCD sensor is provided with its own individual calibration software. This software must be installed on the PC.See the provided installation and configuration instructions for in-stalling the calibration software OrderNo.:9000-608-69/01.

Use of the Appliance

12. Working with DR 6 The CCD sensor can be used with or without right-angle holder (upon request). To prevent any position faults, we recommend using a right angle holder.

If the DR 6 is operated with VETExam Intra or via CREasy, x-ray images can either be created in high resolution mode (22.7 LP/mm) or stan-dard mode (11.35 LP/ mm). The transmission time is 4 to 16 seconds de-pending on the sensor size and setting.

12.1 Creating x-ray images•StartthePC

•Startthex-raysoftware.

•Selecttherequiredscanningmode.

•ActuatecapturingcapabilitiesofDR6inthex-ray software.

Avoidable exposure dose: Before the image is taken, both LEDs (yellow and green) must be il-luminated on the CCU controller (1), otherwise the image cannot be saved and the image must also be repeated.

Do not drop the CCD sensor or subject to pressure.

•Positionthehygienicprotectivecover(15)over the right angle holder with the CCD sen-sor (2) or only over the CCD sensor. Position the CCD sensor.

Hygienic protection: Hygienic protection covers should be used for reasons of infection.

Hygienic protective covers are not to be reused.

•Createexposurevaluesonthex-rayappli-ance.

•TriggertheX-rayexposure. The CCD sensor automatically detects when x-ray radiation occurs and automatically trans-fers the image to the software.

The CCU controller is not ready to cap-ture on the PC during the transmission of image data (yellow LED not illumina-ted). As soon as the yellow LED is illumina-ted, the system is ready for capturing again.

If there is any damage, the system is not to be put into operation.

13. Disinfection and Cleaning

Only use disinfection and cleaning agents specifically approved or manufactured by DÜRR MEDICAL. Other disinfection- and cleaning-preparations can damage the CCD sensor or the CCU controller. Using other disinfection- and cleaning-preparations is unintended usage. The manufacturer is not liable for any damages arising from incorrect usage. The operator bears all risks and liabilities.

13.1 CCU Controller

Damage to the CCU controller: No liquid is allowed to contact the inside of the device. Liquid can damage the system. Therefore, do not spray the CCU controller with cleaning- and disinfection-solutions or put it in an autoclave or an im-mersion bath.

Disinfection should be carried out with disinfec-tantwipes(e.g.OrochemieB30)oralternativelyusingdisinfectantspray(e.g.OrochemieB60)on a soft, lint-free cloth.

15. Recommended exposure times

Avoidable exposure: The maximum exposure time of 500 ms is not be exceeded. The image can become unusable if the exposure time is too long.

Check the following appliance-specific standard values and adapt as required.

Reference conditions:

•Housecat(approx.6kg)tomediumsizeddog(approx.20kg)

The exposure times indicated in the table for tube length 20 cm were determined with a dental x-ray unit with DC emitter (focal point 0.7 mm; tube length 20 cm). The exposure times for tube length 30 cm were calculated from the exposure times for tube length 20 cm.
