Transcranial doppler sonography

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Transcranial Doppler sonography (TCD) was first introduced by Rune Aaslid and colleagues in 1982 to noninvasively measure blood flow velocities in the major branches of the Circle of Willis through the intact skull.1 A 2-MHz frequency pulse wave ultrasonic beam penetrates the skull and allows returned echo signals to be detected. The frequency shift of the returned echoes is calculated using the Doppler equation fD = 2 fo v cosθ/(c - cosθ), where fD is Doppler shift, fo is the emitting frequency, v is the scatterer speed, θ is the Doppler angle, and c is the sound propagation speed.
