“…The lack of water and electricity is generally coupled with a lack of public infrastructure such as roads and railway links [26]. These are important in any health infrastructure as they allow access to hospitals, transport of equipment and consumables and, in the case of imaging, access for companies that provide maintenance of radiological equipment.…”

“…These are important in any health infrastructure as they allow access to hospitals, transport of equipment and consumables and, in the case of imaging, access for companies that provide maintenance of radiological equipment. Embedded service contracts exist where equipment is designed specifically for regular servicing [26]. Accessibility to rural areas that do not have public infrastructure may prove too costly for suppliers of sophisticated equipment.…”

Paediatric radiology seen from Africa. Part I: providing diagnostic imaging to a young population

Paediatric radiology requires dedicated equipment, specific precautions related to ionising radiation, and specialist knowledge. Developing countries face difficulties in providing adequate imaging services for children. In many African countries, children represent an increasing proportion of the population, and additional challenges follow from extreme living conditions, poverty, lack of parental care, and exposure to tuberculosis, HIV, pneumonia, diarrhoea and violent trauma. Imaging plays a critical role in the treatment of these children, but is expensive and difficult to provide. The World Health Organisation initiatives, of which the World Health Imaging System for Radiography (WHIS-RAD) unit is one result, needs to expand into other areas such as the provision of maintenance servicing. New initiatives by groups such as Rotary and the World Health Imaging Alliance to install WHIS-RAD units in developing countries and provide digital solutions, need support. Paediatric radiologists are needed to offer their services for reporting, consultation and quality assurance for free by way of teleradiology. Societies for paediatric radiology are needed to focus on providing a volunteer teleradiology reporting group, information on child safety for basic imaging, guidelines for investigations specific to the disease spectrum, and solutions for optimising imaging in children.

Broadly Available Imaging Devices Enable High-Quality Low-Cost Photometry

et al. 2015

This paper demonstrates that, for applications in resource-limited environments, expensive microplate spectrophotometers-which are used in many central laboratories for parallel measurement of absorbance of samples-can be replaced by photometers based on inexpensive and ubiquitous, consumer electronic devices (e.g., scanners and cell-phone cameras). Two devices-i) a flatbed scanner operating in transmittance mode and ii) a camera-based photometer constructed from a cell phone camera, a planar light source, and a cardboard box-demonstrate the concept. These devices illuminate samples in microtiter plates from one side, and use the RGB-based imaging sensors of the scanner/camera to measure the light transmitted to the other side. The broadband absorbance of samples (RGB-resolved absorbance) can be calculated using the RGB color values of only three pixels per micro-well. Rigorous theoretical analysis establishes a well-defined relationship between the absorbance spectrum of a sample and its corresponding RGB-resolved absorbance. The linearity and precision of measurements performed with these low-cost photometers on different dyes that absorb across the range of the visible spectrum, and chromogenic products of assays (e.g., enzymatic, ELISA) demonstrates that these low-cost photometers can be used reliably in a broad range of chemical and biochemical analyses. The ability to perform accurate measurements of absorbance on liquid samples, in parallel and at low cost, would enable testing, typically reserved for well-equipped clinics and laboratories, to be performed in circumstances where resources and expertise are limited.

“…However, data from recent studies [17,18] suggests that the lack of spare parts may be overly often cited as the problem. When examining equipment, participants in the Engineering World Health (EWH) study only identified 12.3% (120 out of 975) of the broken pieces of equipment as requiring a spare part that could not be found or manufactured in the developing world.…”
