Doppler Flow Velocity System
• Noninvasively evaluate cardiovascular physiology and
function.
• The system consists of four components:
• Pulsed Doppler Transceiver,
• Doppler Signal Digitizer,
• Doppler Workstation,
• and Handheld Probe.
• Surgical warming and real-time integration of ECG signals to
the DFVS software from the Rodent Surgical Monitor+.
• 2mm diameter handheld probe achieves ~15° angles.

Pulsed Doppler Ultrasound
• Achieving consistency and accuracy with
proper measurement angle…
• V = (c Δf) / (2fo cos θ)
• θ = angle between velocity vector & beam
