Samsung Unveils Advancements in Radiation Safety with New S-AEC Technology
Seoul, Tuesday, 4 March 2025.
Samsung’s Auto Exposure Control (S-AEC) technology reduces radiation exposure by over 40% while preserving image quality, enhancing patient safety in portable X-ray imaging for abdominal scans.
Groundbreaking Clinical Study Results
A comprehensive study involving 421 patients has demonstrated remarkable improvements in radiation safety through Samsung’s innovative S-AEC technology. The research, conducted at Samsung Medical Center, divided participants into three distinct groups: one manual control group and two S-AEC groups with target radiation doses of 5 and 3.54 microgray (µGy) respectively [1]. The findings revealed significant reductions in exposure index (EI) variation, decreasing by 60% and 55% in the respective S-AEC groups compared to manual control [2].
Technical Innovation in Portable Imaging
The S-AEC technology represents a significant advancement in portable X-ray capabilities, extending beyond traditional fixed-unit limitations. This innovative system automatically detects body areas requiring dose adjustment and optimizes radiation exposure according to individual patient body types [3]. What makes this particularly noteworthy is its application in mobile settings, enabling AEC-assisted imaging in hospital rooms and intensive care units - a crucial benefit for patients with limited mobility [4].
Clinical Impact and Safety Improvements
The technology has demonstrated particular effectiveness in abdominal imaging, traditionally one of the more challenging areas for portable X-ray diagnostics. According to Professor Chung Myung-jin of Samsung Medical Center, the system maintained diagnostic quality while achieving a remarkable radiation reduction of over 40% [1]. The study confirmed consistent visualization quality for critical organs including the liver, kidneys, and intestines, while reducing the dose area product (DAP) by up to 44% [2].
Future Implications for Healthcare
This development marks a significant milestone in medical imaging technology, as emphasized by Jang Woo-young, head of Samsung Electronics’ Digital X-ray Business Team. The implementation of S-AEC in mobile digital X-rays not only enhances image quality but also reinforces patient safety through minimized radiation exposure [3]. The technology presents new possibilities for patient radiation dose management, potentially setting new standards for medical imaging safety protocols [4].
