Design Specifications

dDopp is an ultrasound system that can be used with a laptop computer to record, store, review, share and transmit images. The scanner is embedded in a tough countersink block of aluminum that also serves as a heatsink to cool the device. The scanner comes with dDoppSoft, customized software that can be installed on any Windows computer and is available in 9 different languages. The technology price includes the dDopp engine, 2 detachable probes, power supply, two li-polymer 12V batteries, waterproof USB cable, dDoppSoft, and a waterproof and shockproof case. Scanning modes include B-Mode, M-Mode, Color Flow, Pulsed Wave, Continuous Wave, and Power Doppler. Other features include Trapezoid Imaging, Dual Imaging, Quad Imaging, and Compounding. The system is also equipped with scanning presets for common applications such as liver, kidney, and pancreas. Images can be stored on the computer's hard drive and transmitted via email or DICOM server. dDopp is equipped with 12 V and USB connectors. The device can be powered via a wall outlet, 12 V rechargeable battery (provided), 12 V car adapter (provided), or solar power. The battery life of the system is about 5 hours but varies depending on the scanning mode. It takes 5 hours to recharge the device using a 12 V battery and 8 hours when using solar power. The scanner automatically shuts off when the software is closed or after 15 minutes of inactivity. Dimensions: 353 x 166 x 35 mm Weight: 1.8 kg

Product Schematics

Technical Support

The software includes an auto diagnostic feature that allows an untrained user to be remotely connected to a radiologist to perform the diagnosis. Otherwise, specific training and skill in ultrasound imaging are required to operate the system. The manufacturer provides training upon request and the packaging comes with a user manual. The purchase of the system includes a two year warranty. There is no preventative maintenance required.

Replacement Components

The probes can be replaced after about 15 years and batteries when drained.


The estimated lifetime is 10-15 years. The dDopp does not contain any mechanical parts which extends its lifetime.

Manufacturer Specified Performance Parameters

Uni-Com set out to design an Ultrasound that is: easy, fast, and complete with general applications, and that meet the requirements of a color doppler ultrasound specifications    

Vetted Performance Status

dDopp was incorporated into a study on the viability and potential of implementing a telemedicine network in Bolivia.


Do not store the scanner in direct sunlight. The machine was certified to be safe with a CE 0482 certificate in 2019 and an ISO 13485:2016 in 2021.

Complementary Technical Systems

The ultrasound requires a computer, battery, or electric power source to use the medical equipment.

Compliance with regulations

The Ultrasound obtained a CE mark in 2019, ISO certificate in 2021, and DICOM compliant

Evaluation methods

dDopp was tested against the standard

Other Information

A workshop was recently held by the Le Centre d’Expertise et de Recherche en Télémédecine et E-Santé (CERTES) in Guinea to train physicians on how to use dDopp. Expert advisors have suggested that the price range for dDopp is pretty high for target setting. Designers should also investigate additional guidelines, such as the WHO Manual of diagnostic ultrasound. Designers should also take social factors into consideration, such as the use of ultrasounds for gender-biased sex selection in some parts of the world.

    Elizabeth says:

    dDopp vetted performance has a reference to an article using superscript “1”. Can this be hyperlinked to the article, or to the research tab? On research tap, please include numbering.

  2. E4C.COMMENTS says:

    Elizabeth says:

    Is dDopp really 12k-16k price? That’s pretty high given they are targeting resource poor regions.

  3. Nordica MacCarty says:

    Is the combustion chamber insulated?

  4. David Klaus says:

    “Pump Type”, “Power Requirement” etc. can be filled in using the pump specifications in the link I posted below. Again, I would clearly specify when specifications like Maximum Flow Rate are for the pump itself or for the system.
