Where should the body midline be positioned during a femur scan?

Positioning the body midline centered on the pad during a femur scan is crucial for obtaining accurate and reproducible measurements of bone density. This alignment ensures that the region of interest, typically the proximal femur, is properly situated within the scanning field. When the midline is centered on the pad, it allows for uniform distribution of the X-ray beam across the femur, minimizing any potential artifacts that could arise from an off-centered scan.

Additionally, centering on the pad helps maintain consistent positioning across multiple scans, which is important for tracking changes in bone density over time. Achieving an accurate baseline measurement is essential for effective diagnosis and monitoring of conditions such as osteoporosis. In contrast, positioning the midline off to one side could lead to localized measuring errors and compromise the integrity of the results obtained during the scan.
