Since 2002, Charles Owusu Aseku has been travelling across Ghana and beyond in search of treatment for a large keloid growth on his neck. The 46-year-old grew increasingly disheartened after undergoing two unsuccessful surgeries and making a trip to South Africa that resulted only in a consultation.
He was preparing for yet another medical journey when, in late February, he took part in Ghana’s first trial of 3D telemedicine technology, which operates via computer screens at the back of a van.

Developed by Microsoft’s research team in collaboration with local doctors and researchers, the initiative aims to facilitate remote medical consultations for patients awaiting surgery or requiring post-operative care in a region with one of the world’s lowest doctor-to-patient ratios.
The project builds on earlier trials in Scotland and has evolved into a portable system with improved lighting and upgraded cameras.
Inside the van, cameras create a 3D model of each patient, which is then displayed on a large computer screen. Multiple doctors can join the consultation remotely and manipulate the 3D model to evaluate the patient’s condition.
“The idea behind the van is to bring specialised care to remote villages that lack access to it … enabling pre- or post-surgical consultations,” explained Spencer Fowers, principal software developer and lead of the 3D-telemedicine project at Microsoft Research.
The initiative also allows patients to receive multiple medical opinions. During Aseku’s session, doctors from Rwanda, Scotland, and Brazil participated, an experience that gave him renewed optimism.
"I see many doctors here, and I am very happy because each of them brings their expertise—maybe they will find a solution to my problem," said the 46-year-old.
Researchers hope that the trial at Koforidua Regional Hospital, located in Ghana’s eastern region, will serve as the foundation for a broader project that expands the service and explores additional applications.
The use of telemedicine has increased in recent years, particularly since the COVID-19 pandemic. Experts believe that such digital tools could be especially beneficial in Africa, where specialist doctors are scarce for the continent’s 1.4 billion people.
George Opoku, 68, was initially referred to the Korle-Bu Teaching Hospital in Accra, nearly 100 kilometres from Koforidua Hospital, which is much closer to his home. He had first sought treatment for sarcoma, a rare type of cancer that affects the bones and soft tissues.
Upon learning about the 3D telemedicine trial, his doctor enrolled him in the programme, sparing him the additional costs and strain of long-distance travel.
“This time, I simply had to sit in a van and introduce myself and my condition to not just one doctor, but several. I was able to answer all their questions, and I am hopeful they will discuss my case and find a cure for me,” Opoku said. “I already feel better and optimistic.”
One of the main challenges facing the project is the lack of stable internet connectivity, a common issue in Africa’s remote regions.
At the Korle-Bu Teaching Hospital, the technology is benefiting patients in need of plastic surgery. Due to a shortage of plastic surgeons, patients often have to consult with different doctors during each visit.
Dr Kwame Darko, a consultant plastic surgeon at the hospital and one of the project’s principal investigators, stated that 3D telemedicine could enable patients to be examined by multiple doctors in a single session.
Dr Ahensan Dasebre, chief resident doctor at the National Reconstructive Plastic Surgery and Burns Centre at Korle-Bu, who is not involved in the project, believes that 3D technology has the potential to make a significant impact if adopted widely in Ghana and beyond.

“We are already facing a shortage of doctors to adequately care for the population,” he said.
“If someone is in a remote area without access to specialised services but requires them, the referring doctor could use this telemedicine system to ensure the patient receives the best possible care.”
