Samsung Advances Patient Safety with Radiation Optimization Technology
Seoul, Tuesday, 4 March 2025.
Samsung Electronics and Samsung Medical Center published a white paper highlighting the S-AEC technology in mobile X-ray devices, achieving over 40% reduction in radiation while maintaining imaging quality.
Groundbreaking Radiation Control Technology
Samsung’s innovative S-AEC (Auto Exposure Control) technology represents a significant advancement in medical imaging safety. The system automatically detects body areas requiring dose adjustment and optimizes radiation exposure based on individual patient body types [1]. This breakthrough enables uniform image quality in portable imaging while minimizing radiation exposure, addressing a crucial healthcare safety concern [2].
Clinical Study Demonstrates Significant Results
The comprehensive study, led by Professor Chung Myung-jin of Samsung Medical Center, analyzed 421 patients using Samsung Electronics’ mobile digital X-ray GM85. The research compared three distinct conditions: two groups using S-AEC with target radiation doses of 5 micrograys (µGy) and 3.54 µGy, and a control group without S-AEC [1]. The results were remarkable, showing a reduction in exposure index (EI) variability by 60% and 55% respectively in the S-AEC groups, while the dose area product (DAP) decreased by 27% and 44% depending on the target radiation dose [2].
Enhanced Clinical Applications
The technology’s significance extends beyond radiation reduction. The S-AEC function has overcome traditional limitations of AEC systems, which were previously confined to fixed digital X-ray devices with ion chambers [2]. This advancement has particular importance in abdominal radiography, where achieving proper exposure has historically been challenging due to lower tube voltage requirements compared to chest imaging and variations in patient body types [1].
Future Implications for Healthcare
The implementation of S-AEC technology marks a crucial step forward in medical imaging safety. As digital health technologies continue to evolve [5], this innovation demonstrates Samsung’s commitment to advancing patient care through reduced radiation exposure while maintaining diagnostic quality. The technology particularly benefits patients in intensive care units and those with mobility issues, who can now receive optimized imaging care directly at their bedside [2].
