New bioacoustic signal processing techniques

The engineering principles and techniques applicable to the study and eventual non-invasive detection of aneursyms are being studied at the University of Cincinnati. Reported statistics indicate the ruptures of a subarachnoid aneurysm is the cause of 2% of all sudden deaths, is 68% mortal and leaves 21% mentally deficient otherwise. Surgical survival after hemorrhage is rated at 77% and 90% if detected. Statistics indicate that a patient's chances for a productive life are good if the aneursym can be detected and surgically treated. Approximately 12% of all polycystic and 15% of al migrane patients have aneurysms. These statistics are not high enough to warrant the risk of angiography for pre-bleed analysis however. Angiography, which entails patient risk and hospitalization, is the only presently available test for the above conditions.
