Development of a universal medical X-ray imaging phantom prototype.

Area of Science:

• Medical Imaging
• Radiological Physics
• Quality Assurance

Background:

• Diagnostic X-ray imaging relies on consistent image quality for accurate medical diagnoses.
• Current quality assurance (QA) programs utilize expensive, modality-specific phantoms requiring specialized training.
• A universal phantom could streamline QA, reduce costs, and simplify training across various X-ray systems.

Purpose of the Study:

• To design and manufacture a prototype of a universal phantom for image quality assurance.
• To create a single phantom applicable to general radiography, fluoroscopy, mammography, and CT scanning.
• To develop an easy-to-use phantom enabling automatic analysis and reporting, particularly beneficial for low-income countries.

Main Methods:

• Investigated commercially available phantoms and essential image quality parameters for different X-ray modalities.
• Designed a universal phantom prototype focusing on ease of use and cost-effectiveness.
• Explored various materials for phantom housing and inserts, considering physical properties, machinability, and cost. Utilized 3D modeling for prototype manufacturing, including 3D-printed and machined components.

Main Results:

• Successfully developed a prototype of a universal X-ray imaging phantom.
• The prototype is suitable for multiple imaging modalities, easy to use, and cost-effective to manufacture.
• A PCT International Patent Application (No. PCT/IB2016/051165) has been filed for this technology.

Conclusions:

• A universal phantom prototype has been developed, meeting the goal of a single device for multiple X-ray imaging modalities.
• The prototype offers a simplified, cost-effective solution for quality assurance in diagnostic imaging.
• This innovation has the potential to improve healthcare accessibility and efficiency, especially in resource-limited regions.
