A powerful tool for X-ray imaging technology development – the multi-functional X-ray imaging platform


Published:2024-10-30  10:17

【Technical Introduction】
X-ray radiographic imaging technology is extensively utilized in medical diagnostics and industrial non-destructive testing (NDT). By exploiting the penetrating capabilities of X-ray photons, this technology offers non-invasive and non-destructive methods for examining internal structures and detecting flaws. Nevertheless, the majority of X-ray imaging equipment used in Taiwan is imported overseas, with specifications and parameters limited by the original manufacturers' designs, restricting flexibility in addressing diverse testing needs.
To overcome these challenges, NARI has developed a multi-functional X-ray imaging platform. This platform features a 7-axis motion system that supports various scanning modes and allows for flexible replacement of key components. Furthermore, the platform integrates proprietary data acquisition systems, image calibration, and 3D image reconstruction algorithms, effectively meeting the requirements of a wide range of X-ray imaging applications. This versatile platform significantly enhances the development of new X-ray systems and components, reducing product design and development time period while lowering associated costs.

【Project Planning/Technical Application】
The multi-functionality of this platform enables itself to support various X-ray imaging scanning modes, making it be applicable for across a wide range of medical and industrial fields. These applications include medical chest imaging, orthopedics, dentistry, mammography, veterinary scans, as well as industrial non-destructive testing (NDT) and security inspections. The platform is highly effective in assisting those organizations engaged in the development of X-ray imaging technologies by facilitating concept validation and system parameter optimization. This capability significantly shortens the product development cycles and reduces associated costs. Furthermore, the platform offers measurement services for critical X-ray imaging performance indicators of the key components, such as modulation transfer function (MTF) and noise power spectrum (NPS).
 
【Future layout】
Building on the foundation of this platform, NARI will continue advancing the development of the cutting-edge X-ray imaging technologies, including spectral radiography and material decomposition, high-resolution 3D-CT, and high-energy X-ray imaging. Moving forward, NARI plans to collaborate with domestic academic, research, and medical institutions to further broaden the applications of X-ray imaging technology. The goal is to enhance the competitiveness of domestic X-ray imaging technologies and contribute to the growth of a robust, X-ray-related industry.
