Ultrasound Measurement Techniques For Determination Of Limb Volume

Precise measurements are needed to estimate limb volume changes due to body fluid shifts. The accuracy of the estimates must be in the range of a few % if physiological changes of muscle, skin and vessels will be detected. Ultrasonic methods are suitable to accomplish the task of limb volume determination. Two methods are described in this paper. 1. Limb volume measurement device for limb cross sectional estimates (LVMD). 2. Limb volume determination detecting irregular surfaces by echo principles (Contactless Contour). The former method functions by attaching probes to the skin surface, the latter by mechanically moving measured of three transducers (probes) the ultrasound probes around the limbs. Both methods come up to a measurement accuracy of 2%. arranged around the subject's limb in a plain triangle, similar to an isosceles. The probes generate
