This is a new colour Doppler Edan U50 Ultrasound machine. It was purchased by us as our shop front / demo unit. This machine has been taken out of its box on only two occasions, and has a total powered on time of under 30 minutes. It includes two transducers (a microconvex for small animal abdominal work, and a phased array for cardiac scans) which have had less than 5 minutes’ active scanning time.
The reason we are destocking this unit is because a larger company that we work with, now part of the CVS Group, is promoting the Edan range. As we cooperate with this company and run training courses with them, there is no need for us to also carry stock of this range. This obviously presents a fantastic opportunity for a small animal vet practice looking to get started with Colour Doppler, but on a limited budget. We are pricing this unit below even our original distributor purchase price from Edan. Today’s price would be even higher, due to the devaluation of the Pound against the US Dollar.

More about the Edan U50 Prime
The U50 Prime masquerades as an entry level colour Doppler system, but inside its unassuming shell is a whole host of advanced technologies not normally found in the sub-£15,000 price range. These include:
- Speckle reduction technology: speckle is an inherent part of ultrasound imaging and can often be useful (it is, after all, what speckle tracking relies upon – very much ‘in vogue’ in the echocardiography world at the moment), but excessive speckle can make discerning individual reflectors difficult or impossible. Improvements in resolution have helped to reduce the appearance of speckle in leading ultrasound systems, but Edan have gone a step further. In line with big names like GE and Philips, Edan have taken advantage of their advanced electronic transducer design to send pulses into the body at different angles, allowing the returning signals to be decorrelated through spatial compounding. When the echoes from different angles are summed, genuine reflectors will be present across all of them and reinforced; speckle, however, is random, and will therefore be greatly reduced by the summing of the echoes. This is much more effective than frame averaging techniques, and also means that there is no sacrifice made in terms of frame rate.
- Contrast resolution: as well as reducing unnecessary speckle ‘noise,’ spatial compounding also enhances contrast resolution. This can make all the difference when scanning difficult patients, particularly for cardiac work or early pregnancy diagnosis.
The U50 Prime also utilises all the technologies you would expect from a world-leading manufacturer such as Edan:
- Phase inversion harmonic imaging: harmonics result from the propagation of sound waves through the body, and as such, are not generated in the first few cm of travel, which usually contains the most artefact-causing reflectors (such as fat). As a result, harmonics deliver a cleaner, more diagnostic image (as well as higher resolution due to their higher frequencies), and harmonic imaging is now the gold standard in ultrasonography. Phase inversion harmonics involves sending two pulses, one 90 degrees out of phase with the next. When they are summed together, the fundamental frequencies cancel out, but the harmonic frequencies are summed.
Battery life: 90 minutes.
