Transcranial Doppler Device

  • Albrecht G. Harders

Abstract

In 1955, Leksell [116] found in making echoencephalographic recordings that ultrasound could penetrate the skull. Due to the reflection of ultrasound waves on the skull and on brain structures of various densities and sound conduction velocity, indirect space-occupying lesions could be demonstrated.
