SIUI Portable DR System Featured in Leading International Public Health Journal for Its Low-Radiation Study

In January 2025, the internationally renowned public health journal PLOS Global Public Health published an article titled "Assessment of Scattered and Leakage Radiation from Ultra-Portable X-ray Systems in Chest Imaging: An Independent Study." The study was primarily led by Professor Leonie E. Paulis from the Doctors Without Borders Organization in Amsterdam, Netherlands, the Digital Health Division of the Stop TB Partnership in Geneva, Switzerland, and the Department of Medical Physics at Màxima Medical Center in Veldhoven, Netherlands, and was conducted at the Department of Radiology and Nuclear Medicine at Maastricht University Medical Center, Netherlands.

The research focused on measuring scattered and leakage radiation doses from portable X-ray devices to provide scientific evidence for radiation safety guidelines. The SIUI SR-1000 was the only ultra-portable X-ray device from China included in the study. The results of the study indicate that in most chest X-ray (CXR) screening scenarios, when appropriate radiation safety precautions are taken, the total scattered and leakage radiation dose of the SR-1000 remains below the international limit of 1 mSv per year, which is significantly lower than the occupational exposure limit of 20 mSv per year for radiographers. This indicated that the device ensures minimal radiation risk for user safety while enhancing screening efficiency.

Portable X-ray devices are highly suitable for use in resource-limited community settings, particularly for CXR screening of tuberculosis (TB). Although TB is a curable disease, it remains the leading cause of death among infectious diseases worldwide. Early detection and diagnosis are crucial for TB control and can be achieved through systematic and large-scale CXR screening of high-risk populations, facilitating targeted patient classification and subsequent molecular diagnostic testing, which is both scarce and costly. The World Health Organization (WHO) recommends CXR as a key screening technique for early TB detection in both children and adults at high risk.

At the UNION World Conference on Lung Health in November 2024, SIUI and Sinopharm showcased its portable DR system integrated with AI-assisted TB diagnostic solution. This solution enables rapid deployment for TB screening in remote areas. Since 2023, a nonprofit organization DOPASI in Pakistan has applied this solution for the screening of over 8,031 individuals, detecting approximately 219 TB cases, including TB contacts and prisoners, and has provided preventive treatment to halt disease progression. In January 2025, the National Center for Infectious Diseases of China conducted a TB screening initiative, utilizing SIUI portable DR system with AI-powered TB diagnostic solution. Through rotational deployment and active screening in multiple communities, this solution significantly improved efficiency, ensuring early detection, early diagnosis, and early treatment. This proactive approach has effectively reduced TB incidence rates and enhanced public health levels.

SIUI TB screening imaging solution consists of a lightweight X-ray generator, wireless flat panel detector, imaging workstation with AI diagnostic function, portable stand, and carrying backpack. The low-dose portable X-ray generator independently developed by SIUI possesses multiple patented technologies to minimize scattered and leakage radiation through tube current control, energy compensation, and shielding enhancements. The high-sensitivity wireless flat panel detector, combined with proprietary low-dose imaging post-processing technology, provides high-resolution, high-contrast images at minimal radiation doses. The user-friendly device offers extended battery life and supports one-click AI diagnosis, significantly improving workflow efficiency and delivering a flexible, reliable imaging solution for healthcare professionals.

As a listed provider in the Global Fund’s TB Screening Recommended Equipment Directory, SIUI adheres to a people-oriented design concept, ensuring flexible deployment with low-radiation operation across various environments. Whether deployed in mobile medical vehicle, temporary screening stations, or remote mountainous areas, this protective-free device efficiently supports rapid and large-scale TB and chest disease screenings, guaranteeing a safe and effective screening process with minimal risk of radiation exposure.
