What type of collimation is used in a fan beam scanner?

Explanation:
Fan beam scanners utilize fan-shaped collimation to create a specific geometry for capturing data during the bone densitometry process. This type of collimation allows the scanner to send and receive X-ray beams in a wide, fan-like shape, which effectively covers a larger area of the bone being analyzed with each pass. This design enhances the efficiency and accuracy of the imaging process, as it can acquire data over a larger field of view while maintaining the necessary precision for measuring bone density. The fan shape is crucial for the geometry of the scanning technique and is tailored to optimize the resulting image quality and data precision in bone densitometry assessments.
