What effect does patient motion have on spatial resolution?

Patient motion negatively impacts spatial resolution because it leads to blurring and distortion of the images obtained during fluoroscopy. Spatial resolution refers to the ability to clearly distinguish small details in an image. When a patient moves during imaging, different areas of the anatomy can overlap or shift, resulting in a loss of detail and the potential to misinterpret structures. This blurring effect compromises the clarity needed for accurate diagnosis and assessment.

In fluoroscopy, maintaining a stable and motionless position is crucial for ensuring high-quality images. Techniques such as using immobilization devices or instructing the patient to hold their breath during images can help mitigate the effects of motion. The relationship between patient motion and spatial resolution underscores the importance of patient cooperation and the use of proper imaging techniques to achieve optimal diagnostic outcomes.
