Transcranial Doppler System – EK-1000B

Product Overview The EK-1000B Transcranial Doppler (TCD) System is a compact, portable neurodiagnostic solution for hospitals, clinics, and private practices. This Class II medical device (CE, ISO certified) delivers reliable cerebrovascular assessme

What Is TCD?
TCD is a non-invasive ultrasound test that measures blood flow velocity in major cerebral arteries. Like a "radar" for the brain, it provides real-time hemodynamic data through the circle of Willis—without contrast agents or radiation.

Key Features
Function Clinical Value
Routine Diagnosis Evaluate stenosis/occlusion, assess autoregulation, monitor ICP, support brain death determination
Flow Velocity Monitoring Real-time hemodynamic assessment; detects right-to-left shunts 3x more effectively than echocardiography
Stenosis & Occlusion Diagnosis High sensitivity/specificity for intracranial arterial stenosis
Vasospasm Detection 89–98% sensitivity/specificity for SAH-related vasospasm
Multi-Gate Display 4-window simultaneous display + M-mode for multi-depth comparison
Embolic Detection Spindle-wave embolus recognition for stroke risk screening

Clinical Evidence
Vasospasm: TCD shows 89–98% accuracy for SAH-related vasospasm

Right-to-Left Shunt: Detection odds 3x higher with TCD vs. echocardiography (2026 study)

Stroke Prevention: Recommended by AHA for vasospasm monitoring
