    This study introduces a novel image processing method for digital subtraction angiography, extracting temporal information to create functional images. This technique enhances the analysis of organ perfusion and blood flow dynamics.

    Area of Science:

    • Medical Imaging
    • Radiology
    • Image Processing

    Background:

    • Digital subtraction angiography (DSA) provides anatomical detail but largely ignores temporal information.
    • Existing DSA analysis primarily focuses on static anatomical structures.

    Purpose of the Study:

    • To present a novel image processing method for DSA that utilizes temporal information.
    • To generate color-coded functional images from DSA sequences.
    • To extract quantitative parameters for assessing organ perfusion and blood flow.

    Main Methods:

    • Utilizing the timed sequence of digital images from DSA.
    • Developing a pixel-by-pixel image processing technique.
    • Extracting parameters MAX, T-MAX, and T-1/2 MAX from time-density curves, analogous to nuclear medicine time-activity curves.

    Main Results:

    • Generated color-coded functional images representing temporal information.
    • Quantified organ perfusion, blood transit time, and initial contrast delivery.
    • Demonstrated utility in analyzing myocardial, cerebral, and renal circulations.

    Conclusions:

    • The described method effectively extracts and visualizes temporal information from DSA.
    • This technique offers enhanced insights into organ perfusion and vascular dynamics.
    • Potential advantages include superior spatial, temporal, and contrast resolution for diagnostic imaging.
