Summary
The BodiiRay digital radiography system demonstrates comparable image quality to commercial systems, offering sufficient diagnostic confidence for clinical use. This affordable medical imaging technology shows promise for sustainable development in healthcare.
Area of Science:
- Medical Imaging Technology
- Digital Radiography Systems
- Sustainable Development in Healthcare
Background:
- Research and development of affordable digital radiography systems under the brand name BodiiRay by the National Science and Technology Development Agency (NSTDA) in Thailand.
- Implementation of image restoration and enhancement techniques for improved medical imaging.
- Focus on sustainable development and affordability of medical imaging technology.
Purpose of the Study:
- To evaluate the image quality of the BodiiRay digital radiography system.
- Comparison of BodiiRay system performance against commercial systems using phantom and volunteer imaging.
- Assessment of diagnostic utility for various anatomical regions.
Main Methods:
- Phantom image evaluation by experienced observers for high-contrast resolution, low-contrast detectability, and grayscale differentiation across chest, abdomen, and extremity settings.
- Clinical evaluation of volunteer images by specialized radiologists using visual grading scales for anatomy visibility, image quality satisfaction, and diagnosis confidence.
- Comparative analysis with two commercial digital radiography systems (Fujifilm FDR Go and Siemens YSIO Max).
Main Results:
- BodiiRay phantom image quality was comparable to commercial systems, with slight advantages in low-contrast detectability and grayscale differentiation over Fujifilm FDR Go, and high-contrast resolution over Siemens YSIO Max.
- Volunteer image analysis showed high percentages of scores ≥4 (61-99% for chest, 23-92% for abdomen, 96-99% for extremity).
- Average scores for volunteer images indicated good to excellent quality across all evaluated body parts.
Conclusions:
- Phantom studies confirmed the comparability of BodiiRay digital radiography systems with existing commercial options.
- Clinical evaluations demonstrated that BodiiRay system images possess sufficient quality for digital radiography of the chest, abdomen, and extremity.
- The BodiiRay system presents a viable, affordable option for medical imaging, supporting sustainable development goals.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
