Study Notes

PACEMAN Method

  • PACEMAN stands for Positioning, Angulation, Columnation, Exposure, Motivation, and Annotation.
  • The purpose of the PACEMAN method is to evaluate radiographic images.

Image Evaluation

  • 'C' in the PACEMAN method stands for Columnation, which is crucial for controlling the density of the X-ray image.
  • 'mAs' in the PACEMAN method is significant for controlling the exposure of the X-ray image.

Hand Projections

  • The positioning criteria for the Hand PA Projection according to the PACEMAN method is that the palmar surface of the hand should be at a 90-degree angle to the cassette.
  • The Hand PA Projection detects rotation if the third metacarpal bone is parallel to the radiographic plate.
  • On the radiograph in the Hand Oblique Projection, the entire thumb should be visible, and the first metacarpal bone should be parallel to the radiographic plate.
  • A positioning criteria for the Hand Oblique Projection based on the PACEMAN method is that the X-ray beam should be angled 45 degrees to the medial aspect of the hand.

Medical Engineering

  • The main purpose of the PACEMAN method in medical engineering is to ensure accurate and high-quality radiographic images.
