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
