  • Page 15: Product Description

    Product Description The ORTHORALIX 8500 is a system for rotational panoramic radiography of the dento-maxillo-facial area. The system consists of: • Column to be mounted to the wall or with the optional free standing base • Motor-driven overhead assembly with controls for patient positioning, setting of technique factors and radiographic projection geometry • Cassette drive system with flat cassette for 15x30 cm film • X-ray tubehead, with DC power supply to the X-ray tube • Remote control box and handswitch Operator’s Manual 032-0176-EN Rev. 4...
  • Page 16 All movements for the panoramic radiographic projection are performed by independent motors, which are microprocessor controlled. Along with the Standard Panoramic mode, the ORTHORALIX 8500 provides a special child projection, designed to further reduce radiation dosage and conform the image to the child’s dentition.

  • Page 19: Preliminary Procedures

    Preliminary Procedures Film selection The ORTHORALIX 8500 is supplied with a 15x30 cm panoramic film cassette loaded with a Kodak Lanex Regular intensifying screen. The recommended film for use with this screen is Kodak T- Mat G film (PAN/TMG15). A starter pack of film is provided for calibration and demonstration purposes. It is strongly recommended that a supply of fresh film is obtained prior to taking films for diagnostic purposes.
  • Page 20 Gendex Orthoralix 8500 ® To minimize static electricity and other artifacts, the film should be handled only by the edges. Care should be taken to keep the screens and film clean. The film should be stored in a cool, dry location.

  • Page 21: General Operating Procedures

    General Operating Procedures 8.1 Equipment preparation Turn the system on by means of the power on/off switch located on the floor portion of the mounting fixture, at the base of the column. The “power on” lamp on the column control panel will light up, as will lamp for patient size currently selected and the mA and kV displays.

  • Page 22: Program Selection

    Gendex Orthoralix 8500 ® Press the reset key. If during its homing routine the machine finds no internal abnormalities, the red “ready” lamp will be lit. Ready light Note: Before the patient is positioned, all metal articles such as glasses, removable dentures and earrings must be removed.
  • Page 23 Gendex Orthoralix 8500 ® The kV can also be individually adjusted via the up and down keys in the middle part of the control panel. Increasing kV manually from the pre-programmed value will result in an increase in film blackening with a decrease in the contrast. Note that the indicator light will move to the appropriate adult size icon as the kV is manually adjusted.

    On larger children, the anatomy shown on the radiograph may be confined to the dentition and alveolar region Ensure that the computer/software is activated and that the Orthoralix 8500 is turned on (see page 21).
  • Page 26 Completely edentulous patients may close their lips over the bite guide notch. Although the Orthoralix 8500 uses a proprietary software algorithm to compensate for the shadow cast by the spine into the radiograph, the patient must be encouraged not to slouch.
  • Page 27 Gendex Orthoralix 8500 ® Turn on the positioning laser lights by pressing the key on the column control panel. Note: The lasers are timed to go out automatically after 45 seconds. If necessary, pressing the key again will turn them back on.
  • Page 28 Gendex Orthoralix 8500 ® Verify that the ready light is lit, that the computer controlling the panoramic unit is properly connected (green status icon) and that the proper patient size or technique factor is selected. • Just prior to exposure, instruct the patient to place their tongue flat on the roof of their mouth, close their lips around the bite guide, swallow and hold still during the exposure.

  • Page 46 Table 202 - Guidance and manufacturer’s declaration - electromagnetic immunity The Gendex Orthoralix 8500 is intended for use in the electromagnetic environment specified below. The customer or the user of the Gendex Orthoralix 8500 should assure that it is used in such an environment.
  • Page 47 AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Gendex Orthoralix 8500 is used exceeds the applicable RF compliance level above, the Gendex Orthoralix 8500 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re orienting or relocating the Gendex Orthoralix 8500.
  • Page 48 RF communications equipment and the Gendex Orthoralix 8500 The Gendex Orthoralix 8500 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Gendex Orthoralix 8500 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Gendex Orthoralix 8500 as recommended below, according to the maximum output power of the communications equipment.
