    A new phantom set allows for noninvasive evaluation of digital subtraction angiography equipment performance. This tool assesses image quality, system resolution, and the impact of factors like bone and bowel gas on iodine perception.

    Area of Science:

    • Medical Imaging
    • Radiology
    • Biomedical Engineering

    Background:

    • Digital subtraction angiography (DSA) is advancing, necessitating rigorous performance assessment of imaging equipment.
    • Current methods for evaluating DSA systems may not fully capture real-world imaging challenges.

    Purpose of the Study:

    • To design and describe a novel phantom set for the noninvasive assessment of digital subtraction equipment's imaging quality.
    • To provide a standardized tool for evaluating critical performance parameters of DSA systems.

    Main Methods:

    • Development of a phantom set with a remotely controlled transport system.
    • Inclusion of individual patterns to evaluate image intensifier contrast and detail, system low-contrast sensitivity and resolution, geometric distortion, linearity, and stability.
