How long does a narrow fan beam scan typically take?

A narrow fan beam scan generally takes about 1-2 minutes to complete. This scanning technique is designed to provide rapid imaging of bone density with high precision while minimizing the exposure to radiation. The efficiency of the narrow fan beam allows for quick data acquisition, making it feasible for both routine exams and in clinical settings where time is a factor, such as in busy practices or hospital environments.

The speed at which the scan is completed helps ensure patient comfort and reduces the likelihood of motion artifacts that could compromise the quality of the images. Given this context, the completion time of 1-2 minutes is appropriate for a narrow fan beam scan, making it an efficient choice for bone density assessments.
