Verify ultrasound system and transducer performance. Doppler 403™ and Mini-Doppler 1430™ Flow Phantoms help assess system velocities using precision flow rates and proprietary blood-mimicking fluid. Calibrating your Doppler ultrasound systems for accurate flow measurements optimizes the output, offering meaningful results to patients undergoing noninvasive testing

• Precision pulsatile flow mode allows you to reliably test system velocities

• HE (High Equivalency) Gel™ is patented and proven

- Helps ensure all transducers and system settings are fully tested across the entire frequency range from 2 to 18 MHz

- Response of attenuation-to-frequencies over 8 MHz supports accurate axial resolution and penetration depth representative of human tissue1,
