These accessories allow the probe to offset the ultrasound image, which allows better superficial diagnosis to be performed within the focal range of the scanner. The stand-off has a flexible surface that enables a good surface contact for tendon scanning by moulding itself to the contours of the leg. They allow the probe to firmly fit inside the gel material. This allows the probe and stand-off to be held easily in one hand, which ensures a good contact between the probe surface and the stand-off material.
