Goal 3: to improve and promote good health.
Diagnosis and patient management in remote areas, with emphasis on obstetrical and abdominal pathologies.
Health care providers in rural health facilities.
dDoppSoft, the software for the system, is license free.
Between 0-100 units have been distributed. The exact amount of units distributed is unknown.
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, a 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 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 12V and USB connectors. The device can be powered via wall outlet, 12V rechargeable battery (provided), 12V 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 12V 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: 353x166x35 mm;
Weight: 1.8 kg
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 is required to operate the system. The manufacturer provides training upon request.
The purchase of the system includes a two year warranty. There is no preventative maintenance required.
The estimated lifetime is 10-15 years. The dDopp does not contain any mechanical parts which extends its lifetime.
dDopp was incorporated into a study on the viability and potential of implementing a telemedicine network in Bolivia.1 More information on this study can be found in the Research and Standards section.

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.
