摘要： Disclosed is a method and apparatus for repeatably positioning a forearm at a plurality of angular positions for medical analysis. A forearm of a patient is positioned in a support channel within reach of a rotatable handle. The handle can be locked in a number of angular positions, providing a counteractive force as the handle is rotated. The patient rotates and applies a torque force to the handle at selected rotational angles. The forearm and wrist can be scanned in these locked position, and applied torque can be measured to evaluate joint stability.

摘要： A device for positioning a subject's knee during an MRI scan. The device includes foot, knee, and thigh positioning apparatuses. Each of the positioning apparatuses can be translated and/or rotated to allow correct and consistent position of the subject's knee within the MRI magnetic bore. The device includes a user control to facilitate repeat measurements of knee characteristics with reduced intra- and inter-technologist variability.
