Features

  • Deterministic Math: Pure Python standard library implementation with zero external dependencies.

  • Clinical Neuro-Sonology Standards: Implements validated Gosling and Pourcelot hemodynamic formulas.

  • Microvascular Aging & Compliance Biomarker: Early detection of intracranial microvascular stiffening.

  • Model Context Protocol (MCP): Native JSON-RPC tool integration for LLMs and autonomous agents.

client = CerebralPulsatilityIndexClient()
result = client.evaluate_cerebral_pulsatility(
    peak_systolic_velocity_cm_s=98.0,
    end_diastolic_velocity_cm_s=45.0
)
print("Gosling PI:", result["gosling_pulsatility_index_pi"])
