The JorVet Doppler is designed to receive blood flow velocity information by ultrasound. A
specific frequency is transmitted from the probe to the patient.
Technically, the transceiver amplifies a high frequency oscillation output for transmission to the
transducer. The voltage is converted by a piezoelectric crystal (transducer) to ultrasound. The
ultrasound beam is transmitted to blood cells flowing through the arteries or to beating fetal
hearts. The ultrasound beam is reflected by the crystal in the transducer which converts the
ultrasound into a voltage. A Doppler shift occurs between the emission and reception of the
ultrasound beam.
Advantages of using Doppler flow detectors include ease of application, portability, applicability
to hypotensive animals, and usefulness as an audible monitor of the arterial pulse and peripheral
blood flow.
