Study Notes
Radiographic Errors
- The primary cause of most radiographic errors is patient positioning error.
Technique and Projection Errors
- A grid error is not a type of technique and projection error in radiography.
Radiopaque Artifact Errors
- A radiopaque artifact in a radiograph indicates a processing error.
Film Handling Errors
- A dropped film corner in a radiograph indicates a film handling error.
- A black line in a radiograph indicates a film handling error, specifically a static electric discharge.
Contrast Errors
- An image with high and low contrast in radiography results from overexposure or underexposure error.
Anatomical Structure Errors
- The most common anatomical structure that appears ghosted in an OPG error is the vertebral body.
Artifact Errors
- A artifact that resembles its real counterpart, has the same morphology, but appears on the opposite side is a mirror image artifact.
- A black line on the film indicates a static electric discharge error.
Patient-Related Errors
- Patient's shoulders touching the cassette during exposure causes a patient positioning error.
- Patient movement during exposure causes a positioning error, leading to distortion in the radiograph.
Film Defects
- A white spot or patch on the film indicates a film defect.
- A smudge (finger print) on the film is a form of film defect error.
