    A new hydraulic phantom simulates cardiac function for radionuclide cardiology analysis. While designed for quality control, it proves more valuable for training clinicians in interpreting ejection fraction, shunts, and cardiac output.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Biomedical Engineering

    Background:

    • Clinical radionuclide cardiology relies on accurate analysis routines.
    • Existing quality control methods may have limitations.
    • Training for interpreting cardiac function is crucial.

    Purpose of the Study:

    • To develop and evaluate a flow-based hydraulic phantom.
    • To verify analysis routines used in radionuclide cardiology.
    • To assess the phantom's utility in quality control and training.

    Main Methods:

    • Development of a hydraulic phantom with adjustable valve dysfunctions.
    • Simulation of ejection fraction studies (first-pass and equilibrium).
    • Simulation of shunt assessment and cardiac output measurements.
