Measurement and analysis of cerebral hemodynamic parameters in the presence of brain vascular anomalies

Hemodynamic parameters of the blood flow in human cerebral vessels up to the 4th branch levels were measured. A framework based on "Pressure - Velocity" and "Discharge - Energy flow rate" regimen was designed and implemented. This framework makes it possible to detect brain vascular anomalies like arteriovenous malformations and arterial aneurysms depending on hemodynamic parameters, and to monitor the efficiency of the operation. Modification in the low-frequency spectrum of the cerebral blood flow following the operation was detected by the wavelet analysis of the hemodynamic parameters. The results obtained give qualitative and quantitative characteristics of the presence of cerebral blood vessels anomalies and makes it possible to estimate the efficiency of their embolization at operation.
