Study Notes
Patient Motion Artifacts
- Patient motion can significantly impact medical imaging, leading to artifacts.
- Motion can be voluntary or involuntary.
Voluntary Motion
- Voluntary motion is controlled by the patient, like swallowing or breathing.
- These movements during scanning can degrade image quality.
Involuntary Motion
- Involuntary motion is uncontrolled, such as head movement due to injury, intestinal contractions (peristalsis), or heartbeats.
- These types of movements can also produce inaccuracies in images.
Correction Strategies
- Positioning Aids: Using devices to maintain patient stability during the scan.
- Shorter Scan Times: Reducing the duration of the scan can lessen the impact of any movement.
