Developing countries have limited access to medical devices despite the quantity and variety available worldwide, according to a World Health Organization (WHO) study.
The findings indicate that major gaps exist in the availability of medical devices between low-income countries and high-income countries.
In some high-income countries, there is one computer tomography scanner per 64,900 people, but some low-income countries only have access to one per 3.5 million people.
Around ten developing countries do not have a single radiotherapy unit, meaning that 100 million people do not have access to cancer treatment.
The medical devices sales worldwide generated about $210bn in 2008, 80% of which was earned in the Americas and Europe.
The study was released during a forum of Asian health experts in Bangkok, where the WHO discussed how developing countries could get better access to such equipment.
