Positioning
  • Patient is supine and positioned without rotation of the torso
  • Ensure there are no artefacts such as zips or buttons over the area being imaged
  • Centre the midsaggital plane of the patient to the midline of the IR
Critique

 Positioning
 No rotation as evidenced by
  • the pedicles of the vertebrae are the same distance from the spinous processes on each side

Area Covered
  • Outline of the kidneys and the proximal ureter
Collimation
  • Centre: Approximately at the level of Lumbar vertebra L1
  • Shutter A: Open to include kidneys both superiorly and inferiorly
  • Shutter B: Open to include the lateral renal outlines
Exposure
There should be adequate exposure and no patient motion so that the following anatomy is demonstrated
  • the outline of the kidneys
  • skeletal structures such as the posterior ribs and vertebrae
