Robotic Probe
Transcranial Doppler (TCD) is non invasive ultrasound technology used to
evaluate blood flow velocity in the major basal intracranial arteries.
However, the practice of maintaining Doppler signal is not easy in clinical
monitoring. Robotic Probe is just the innovative solution.
Features
-
Two-axis probe azimuth and lateral control make insonation angle and probe position adjustable
-
'Intelligent' embedded robotic software
-
Continuous digital storage of complete Doppler signal in
flash memory
-
Automatically search and mark vessel signals with
different colors
-
Easily track and restore best signals by itself
-
More comfortable and lighter fixation
Applications
-
Detection and monitoring of vasospasm following aneurysmal subarachnoid
hemorrhage
-
Evaluation of the Circle of Willis arterial system and side branch cerebral
circulation
-
Screening for basilar artery stenosis
-
Diagnosis of intracranial stenosis and occlusion
-
Evaluation of intracranial effects of extracranial stenosis,
including assessment of collateral flow pathways
-
Evaluation of vasomotor reserve
-
Support of the diagnosis of brain death
-
Evaluation and monitoring of intracranial blood flow during
surgical procedures.
-
Detection of patent foramen ovale
-
Identification of feeder arteries in AVM’s
-
Application of ambulatory TCD to patients with both
symptomatic and asymptomatic carotid stenosis, and repeat it on a second
occasion
-
Analysis of temporal variability in embolization and
construct optimal recording protocols
-
Study of the pattern of embolization in the patient groups
