New Technology Could Bring Better Disease Detection to Rural Uganda

Researchers from Uganda and Spain are using cloud computing to improve the quality of MRI scans from low-cost imaging systems, a breakthrough that could widen access to advanced diagnostics in underserved communities.

The initiative brings together Mbarara University of Science and Technology (MUST) and the Institute of Instrumentation for Molecular Imaging (I3M) in Spain. The team is using Tyger, a cloud-based imaging platform developed by Microsoft Research, to process MRI images remotely and improve scan quality.

The technology allows MRI machines to focus on collecting signals while image reconstruction takes place in the cloud. Researchers send raw scan data to Microsoft Azure, where specialised tools remove noise and correct distortions before returning clearer images.

The approach tackles a long-standing challenge in many parts of Sub-Saharan Africa, where limited computing capacity and weak infrastructure often affect the quality of MRI images.

The project has particular importance for Uganda, where access to MRI services remains limited. Many patients travel long distances to obtain scans, delaying diagnosis and treatment for conditions such as stroke, head injuries and hydrocephalus.

Eng Dr Johnes Obungoloch, Dean of the Faculty of Applied Sciences and Technology at MUST, said the technology could help bring advanced medical imaging closer to communities that currently lack access to such services.

The collaboration started in 2023 after discussions between I3M and Microsoft Research on ways to address MRI challenges in low-resource settings. Since then, researchers have tested image reconstruction methods and linked the Ugandan MRI system to the Tyger platform.

The team says progress has been significant. According to Obungoloch, researchers have scanned dozens of volunteers since 2025. Early tests produced only partial head images, but the system can now capture full-head scans.

The project is also building local expertise. Students at MUST are receiving training in MRI technology, electronics, system design and signal processing. Community health workers are also gaining exposure to the technology.

Michael Hansen, General Manager of Medical Imaging at Microsoft Research Health Futures, said cloud-based image reconstruction could help deliver high-quality diagnostic imaging without the need for expensive local computing infrastructure.

Researchers believe the technology could help expand access to medical imaging across regions where advanced healthcare equipment remains scarce.
