Dr CADx is a computer aided diagnostic system to help doctors diagnose medical images more accurately in order to provide better patient outcomes and save lives, and to provide pervasive radiology diagnostics in underserved regions.

Why we are building it

Radiologists, being human, are not perfect which limits their diagnostic accuracy. Studies have quantified their diagnostic accuracy to be 70% on average. As a result, of the 3.6 billion medical images that are taken each year, about 1 billion scans are misdiagnosed resulting in patients frequently failing to get the right treatment on time, leading to undue suffering and even death.

Additionally, in many parts of the world, radiologists are in short supply. E.g. an estimated 170 million patients in Africa do not have access to a radiologist to review their medical images.

How we are solving the problem

Dr CADx, through a computer aided diagnostic system that helps doctors diagnose medical images more accurately and at a low cost, will reduce the human errors that have dire consequences for patients and drive up medical costs. By deploying an artificial intelligence system that will be available at any given time of the day — even in remote areas — we will greatly improve the quality of patient management and save lives, especially in the marginalized areas of the developing world.

In the past 6 months we developed a prototype which currently works with chest X-rays to diagnose TB and lung cancer, and achieves an accuracy of 82%. We are currently working on improving the accuracy and the robustness of the system to deal with subtleties of images taken with imaging equipment from different manufacturers, use of varying contrasts etc.

You can be part of this healthcare innovation

We have managed to make the aforementioned progress using our own limited funds. We are now looking for funding to accelerate the pace of development of our solution and take it to clinical trials. We are planning to run a crowdfunding campaign later in 2017, to get the financial support of people like you who also believe that our healthcare systems can do better. Sign-up to our mailing list and you will be the first know when our Indiegogo campaign goes live, and you can make your contribution towards more accurate diagnosis and help save lives.
