    Computer Angiography enhances X-ray imaging by replacing absorption values with dynamic parameters like blood velocity. This new functional imaging method provides easier and faster insights into organ blood dynamics compared to traditional techniques.

    Area of Science:

    • Medical Imaging
    • Radiology
    • Physiology

    Background:

    • Conventional angiography relies on X-ray absorption, offering limited dynamic physiological information.
    • Assessing blood flow dynamics in organs is crucial for diagnosing various medical conditions.

    Purpose of the Study:

    • To introduce a novel functional imaging technique for X-ray angiograms.
    • To develop a new system for advanced angiographic image processing.
    • To evaluate the efficacy of this method in extracting dynamic blood flow information.

    Main Methods:

    • Functional imaging principles were applied to X-ray angiograms.
    • A new image processing system was developed for this purpose.
    • Computed grey or color values, representing dynamic parameters like blood velocity, replaced standard X-ray absorption values at each image point.
