Summary

The study examines whether a mechanical arm ultrasound system provides diagnostic accuracy comparable to expert-performed full ultrasound for detecting key joint components and whether it can reduce acquisition variability without compromising accuracy, as measured by false-positive and false-negative rates.

Conditions

• Hemophilia

Interventions

Type	Name	Description
DEVICE	Mechanical Ultrasound	3D ultrasound imaging is a non-invasive technique. The device consists of a stationary platform and a water-filled rotating drum designed to acquire 3D ultrasound images of the ankles. An ultrasound transducer is mounted on a mechanical arm, which positions and orients it toward the rotating axis of the drum. The collected ultrasound images will be mapped into 3D space, and the volume will be reconstructed using software developed by the manufacturer.
