  IR size: 14 x 17 grid or bucky LW or CW

  patient position: back to the IR, top of the IR should be 1.5-2 inches above the patients shoulders

  central ray: perpendicular to the long axis of the sternum, entering the MSP and 3-4 inches inferior to the jugular notch (t7)

  SID: 60-72 inches

  technique:

  screen: kVp 80 mAs 2

  grid: kVp 102 mAs 8
• Anterior Posterior Axial Projection (Lordotic)

  IR size: 14 x 17 grid or bucky LW

  patient position: upright with back to board, a foot away and lean shoulders back to the board, shoulders should be 3 inches from the top of the board

  Central ray: perpendicular to the IR entering MSP and midsternum, 15-20 degrees cephlad

  SID: 72 inches

  Technique: kVp 133 mAs 3-5
• Posterior Anterior Oblique Projection

  IR size: 14 x 17 grid or bucky LW

  Patient position: upright facing the board, turn the patient 45 degrees and place the shoulder against the board, raise the arms out of the lung field, center the lung field to the board.

  central ray: perpendicular to the IR at the level of T7

  SID: 72 inches

  Technique: kVp 133 mAs 3-5
• Anterior Posterior Oblique Projection


  IR size: 14 x 17 grid or bucky LW

  patient position: upright with back against the board, turn the patient 45 degrees and place the shoulder against the board, raise arms out of the lung field, center the lung field to the board.

  central ray: perpendicular to the IR entering at a level 3-4 inches inferior to the jugular notch

  SID: 72 inches

  technique: kVp 133 mAs 3-5
• LAO (left anterior oblique)


  when the left side of the chest is closest to the bucky while facing the board.

  will result in the right lung being bigger in the image
• RAO (right anterior oblique)


  when the right side of the chest is closest to the bucky while facing the board.

  will result in the left lung being bigger in the image
• LPO (left posterior oblique)


  when the left side of the body is against the board while facing away from the board.

  will result in the left lung being bigger in the image
• RPO (right posterior oblique)


  when the right side of the body is against the board while facing away from the board.

  will result in the right lung being bigger in the image

• indications for the AP axial and AP/PA oblique xrays

  tuberculosis (axial)

  neoplasm (oblique)

  calcification (oblique)
• what is post close used for

  AP oblique projections
• what are the positions for the AP oblique projections

  Right posterior oblique

  left posterior oblique
• what is the right posterior oblique position (RPO)

  back to the board, turn the patient 45 degrees so their right shoulder is against the board

  resulting in the right lung being bigger
• what is the left posterior oblique position (LPO)

  back to the board, turn the patient 45 degrees so their left shoulder is against the board

  resulting in the left lung being bigger
• what are the positions for PA oblique projection

  right anterior oblique

  left anterior oblique
• what is the right anterior oblique position

  chest to the board, turn the patient 45 degrees so the right shoulder is touching the board

  resulting in the left lung being bigger
• what is the left anterior oblique position

  chest to the board, turn the patient 45 degrees so the left shoulder is touching the board

  resulting in the right lung being bigger
• what is anterior away used for

  PA obliques
• post close means the posterior side is closer to the bucky resulting in the posterior lung being bigger
• anterior away means the anterior side is closer to the bucky but the lung away from the board is bigger
