🩻From Diamond Mines to Saving Lives! South African company Lodox Systems has developed a unique full-body X-ray scanner — the Lodox Statscan. It can capture a full-body image in just 13 seconds, while delivering 10 times less radiation than a standard X-ray. 📜 The technology dates back to the 1990s, when engineers at De Beers, a diamond mining company, designed the scanner to detect diamonds being smuggled out of mines. Later, this same technology was adapted for medical use — allowing for rapid and low-dose full-body imaging in emergency situations. 📍 The first Statscan installation outside South Africa was in 2003. Today, Lodox systems are used in hospitals and trauma centers around the world. #SouthAfrica#Innovation#MedicalTech#Lodox#Radiology#TraumaCare#AfricaInTheWorld#Xray#HealthTech
