get_perineurial_thickness

nrv.utils.get_perineurial_thickness(fasc_d: float, nerve_type: str = 'default') → float[source]

Return a fascicle’s perineurium thickness from its diameter. Relationship extract from [1]

Parameters:

  • fasc_d (float) – diameter of the fascicle

  • nerve_type (str) –

    type of nerve containing the fascicle, possible types:

    • ”default”

    • ”sciatic”

    • ”medial popliteal”

    • ”lateral popliteal”

    • ”ulnar”

    • ”radial”

    • ”median”

Returns:

thickness of the perineurium

Return type:

float
