A tool for designing digital test objects for module performance evaluation in medical digital imaging

Area of Science:

• Medical Imaging
• Digital Health
• Image Quality Assessment

Background:

• Medical digital imaging systems incorporate modules like digital display, image compression, processing, film printing, and digitization.
• Performance evaluation of these modules is crucial for maintaining high image quality.
• Existing quality control methods may lack flexibility for diverse digital imaging components.

Purpose of the Study:

• To present a tool for designing computer-generated test objects for medical digital imaging system performance evaluation.
• To enable user-driven design of digital test objects tailored to specific module requirements.
• To facilitate quality control based on established parameters.

Main Methods:

• Development of a software tool for creating digital test objects using an object-oriented approach (Visual C++ 5.0).
• Implementation of a user interface based on the Microsoft Foundation Class Library (MFC 4.2).
• Ensuring compatibility with DICOM 3.0 Part 10 image formats for system integration.

Main Results:

• The tool generates digital test objects usable directly for digital image processing and indirectly for film digitization.
• Quality control parameters include input/output response, resolution, contrast discrimination, noise, geometric distortion, and field uniformity.
• Demonstrated capability through direct use in image processing and indirect use in film digitization.

Conclusions:

• The developed tool provides a flexible and user-driven approach to performance evaluation of medical digital imaging systems.
• It supports quality control for various imaging modules, enhancing overall image quality assessment.
• Compatibility with DICOM standards facilitates integration into existing medical imaging frameworks.
