Single camera three component planar velocity measurements, using two frequency Planar Doppler Velocimetry (2v-PDV) (2005) [PDF]

open access: yes, 2005
The work presented here describes a method that allows three component velocity measurements to be made, quickly and non-intrusively, across a plane in a flow defined by a laser light sheet. The method, two frequency planar Doppler Velocimetry (2v-PDV)

Perioperative ultrasound neuromonitoring: transcraneal Doppler and optic nerve.

open access: yesCirugia y cirujanos, 2020
Monitoring of the neurocritical in the perioperatory is in constant evolution. There are essentially two ultrasonographic application of neuromonitoring: the diameter of the sheath of the optic nerve and transcranial Doppler. Ultrasound-guided neuromonitoring can detect stenosis or occlusion of intracranial arteries, monitor the evolution of patients ...

Low sensitivity of the echocardiograph compared with contrast transcranial Doppler in right-to-left shunt

open access: yesNeurología (English Edition), 2012
Background: Contrast transcranial Doppler (c-TCD) has a high sensitivity for detecting right-to-left shunt (RLS), and is probably higher than transthoracic echocardiography (TTE) and comparable with transesophageal echocardiography (TEE).
