Outcomes and Objectives  

  1. Recognize and operate X-ray equipment.
    1. Recognize and operate radiographic lab equipment.
    2. Explain and follow lab procedures.
    3. Operate the x-ray unit establishing KVP, MA and time settings for any given view and type of imaging.
  2. Describe the rationale for exposing images.
    1. Provide reasons for exposing vertical and horizontal interproximal and periapical images.
    2. Provide reasons for using different size film/sensors./phosphorus plates
    3. Provide reasons for types of images.
  3. Utilize film-holding devices.
    1. State the value and rational for the use of positioning devices in health and safety of patients and to optimum technique.
    2. Identify parts of the device.
    3. Assemble device for each view.
    4. Position patient, film/sensor/phosphorus plate, and device for images.
  4. Apply parallel technique while exposing films of DXTRR.
    1. Position simulated patient (DXTRR) for each projection.
    2. Expose FMX and interproximal images on adult DXTRR.
    3. Expose Pediatric , edentulous, occlusal, and third molar images
    4. Given DXTRR, position the film/sensor/phosphorus plate for any intraoral projection.
    5. Adjust horizontal and vertical tube angulation.
    6. Adjust machine setting for each view.
    7. Expose radiographic surveys on DXTRR according to criteria.
    8. Develop radiographic competence at stated level (according to evaluation checklists) for each radiographic projection in a full mouth series and interproximal series.
  5. Apply parallel technique while exposing film on patients.
    1. While applying aseptic, radiation health, and patient management techniques, expose, and complete evaluation form on three adult FMS at stated levels.
    2. Identify errors and means to correct the errors.
    3. Retake images.
  6. Evaluate films for exposure errors.
    1. Using radiographs produced during this course and evaluation forms, assess diagnostic quality of images according to criteria on evaluation forms.
    2. For each image evaluated, state corrections necessary to improve the quality of the image.
    3. Value importance of producing high quality diagnostic image techniques.
  7. Mount radiographs in film holders when applicable.
    1. Explain mounting procedures.
    2. Given mount frames and packets of radiographs, mount the series in the recommended method,
      1. three adult FMS
      2. one child FMS
    3. Mount all exposed films with 100% accuracy.
  8. Expose a PAN on a patient.
    1. Describe patient positioning, equipment preparation, and exposure time for exposing panoramic projections.
    2. Operate PAN machine.
    3. Practice a PAN setup.
    4. Produce a panoramic radiograph of diagnostic quality using a patient.
    5. Describe procedure using film.
  9. Apply radiation safety methods during exposures.
    1. Employ protection methods for self and patient.
    2. Follow lab rules during/for exposures.
    3. Respond to patient questions and concerns using professional, positive, and informed replies regarding the use of radiation and safety to the patient's health and welfare.
