Doppler 403™ & Mini-Doppler 404™ Flow Phantoms
Ensure years of consistent QC measurements and high quality diagnostic imaging
- Collaboratively designed to better serve your needs
- Go from storage to use in less than 10 seconds
The Doppler 403 and Mini-Doppler 404 Flow Phantoms are second generation devices based on the proven, original designs, and developed with ongoing customer input.
- 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 tissue1,2

Volume flow settings on the phantom support reliable system velocity testing.

Sono Transducer Holder securely holds a transducer in a precise location to help you perform reproducible QC tests.
From routine QA to education and complex research
Doppler 403 Flow Phantom
- The gold standard in Doppler Ultrasound QA
- Measure axial & lateral resolution from the surface to 16 cm deep
- Ideal for cardiology and musculoskeletal (MSK) applications
- Measure small parts resolution
- Lightweight at less than 10 lbs. (4.6 kg)
The Sono Transducer Holder Accessory fits any Gammex phantom including the Sono Family and Doppler Flow phantoms.
- Place a transducer in a precise location in the holder for reproducible tests over time
- Support the transducer cable with the cable hook
- New blood mimicking fluid formulation
- Represents laminar and parabolic flows (velocity-dependent)3
- Increased viscosity and decreased Reynolds number
- No need to ever purchase or store blood mimicking fluid
- Rugged, self-contained, battery-operated
- Easy to useāturn it on, push a button & start testing
- HE Gel can be rejuvenated and your phantom re-validated any time to strengthen your investment
- Exceed ACR, ECR, AIUM and other program requirements
- When combined with the flow controller

The Doppler 403 Flow Phantom is used to test the Doppler color flow velocity measurement.

This represents a measurement of laminar, parabolic flow.
Rejuvenation Will Protect Your Investment
Our Doppler Flow and Sono (B-Mode) phantoms are the only ultrasound phantoms on the market that can be rejuvenated and re-validated. Implementing a rejuvenation program can extend the life of the phantom to 10+ years.
