Transcranial Doppler (TCD), and more recently,
Transcranial Color Doppler and Power Imaging, give detailed information about the flow
velocity in brain arteries and veins. This hemodynamic information is routinely
used in diagnosis of cerebrovascular disease.
The TCD Simulator is a combination of a detailed cerebral hemodynamics model with simulated Doppler, CBF and other hemodynamic monitoring instrumentation. Thanks to recent development in computers, it is now possible to represent detailed hemodynamic events in real time -- this was previously only possible using supercomputers or analog circuits to solve the differential equations. The author of this interactive program is Dr. Rune Aaslid CV [PDF]-- who co-introduced TCD in 1982 and has contributed with numerous publications
and 2 books on Transcranial Doppler.
The Virtual Reality Model has been
integrated with e-book text to give a comprehensive course in Cerebral
Hemodynamics and Transcranial Doppler. Even 3-D models
of the anatomy of the cerebral arteries are included to illustrate the hands-on
ultrasound probe handling.
Cerebrovascular Diseases can be realistically explored and studied in the Professional Version of the Transcranial Doppler Simulator. We have included a comprehensive and detailed study material for understanding a wide variety of neurovascular pathology :
-> Carotid stenosis/occlusion
-> Intracranial Stenosis
-> Cerebral Emboli Detection
-> Cerebral Vasospasm
-> Arteriovenous Malformations
-> Head Trauma
-> Cerebral Circulatory Arrest
-> Diminished Vasomotor Reactivity
-> Reduced/Absent Cerebral Autoregulation
-> Variations in Circle of Willis
The TCD Simulator is compatible with Windows 2000, XP and Vista.
