In this paper, we propose a system for measurement of forearm vessels deformation under loading. This system enables the simultaneous measurement of the force applied by the probe using loadcell and the vessel diameters in ultrasonographic images. In addition, the ultrasound probe can be fixed at any position on the forearm, and the load can be increased gradually by means of a fine-adjustment screw. Using a constant load spring, it is possible to measure without any additional force being applied to the forearm. Nine healthy male participants were recruited. The deformation of vessels at two locations close to the elbow were measured using this system. As a result, it was found that the vessels were twice as hard to deform and the diameter increased by approximately 1mm by tourniquet. The result demonstrated the validity of our measurement system.
