    "body_text": "The proposed workflow begins at the parasternal long-axis view, sweeps while keeping the mitral valve centered, then rotates and angles the probe to align both valves and the septum before final tilting. In proof-of-concept tests across five subjects, predefined image-quality scoring averaged 68.0 percent. The small study establishes feasibility for algorithm-assisted guidance, not autonomous clinical scanning.",
