Paper Abstract

Urination behavior indicates a series of important information for urologist Doctors, to find, for example, prostatic hypertrophy. External, non-contact urodynamic monitors using CW-Doppler principle were built in similar wavelengths with 24GHz electromagnetic wave (λ=12.5mm) and 40KHz airborne ultrasound (λ8.5mm). Both. systems were found having almost equivalent excellence in detecting the Doppler return from. urinary flow simulated by water ejector. However, airborne ultrasound system. seems slightly less expensive although its electronics are more complicated.
