eTracking

The eTracking (ET) function calculates arteriosclerosis indices such as elastic modulus (Ep), which shows the elastic characteristics of blood vessels from the diameter of the carotid artery and blood pressure values, and stiffness parameter (β). The compatible probe for eTracking, see Safety Instruction. NOTE: eTracking requires the optional SOP-F75-11.
