TCD-II
Transcranial Doppler System(Dual Channel)
Transcranial Doppler ( TCD ) system non-invasively measures intracranial blood flow
velocities using pulse echo ultrasounic probe. Based upon spectrum analysis technology,
hemodynamics indices are calculated. Changes of these indices correlate with all kinds of
cranial blood diseases such as vasoconstriction or vasodilation. This technology has proved
to be a very effective way to diagnose cerebral vessel diseases. This method of measurement
is particularly useful for examining the major arteries supplying blood to the brain.
