Diagrammatic Representation of an X-Ray Fluoroscopy System to Illustrate X-Ray Exposure Modality
The primary beam, collimated to a rectangular cross section, enters the patient, typically through the patient’s back. It is attenuated and scattered within the imaging field. The primary beam exposes the subject within the imaging field. The scattered primary beam radiation can expose structures within the subject that are remote from the imaging field.
