EK-1000E Transcranial Doppler System: Advanced Cerebral Blood Flow Analysis for Stroke Prevention & Neurological Assessment

Created on：2026-06-29 11:12

The EK-1000E Transcranial Doppler System (TCD) is a state-of-the-art, non-invasive diagnostic ultrasound device designed for comprehensive cerebral hemodynamic assessment. Leveraging the Doppler effect, this system evaluates blood flow velocity, vessel elasticity, and stenosis severity within the major intracranial arteries of the Circle of Willis. Engineered for both clinical screening and intensive care monitoring, the EK-1000E provides real-time, dynamic data essential for the early detection, prevention, and management of cerebrovascular diseases, including stroke, arterial stenosis, and cerebral vasospasm.

Key Applications & Clinical Functions

      1. Intracranial & Extracranial Vascular Screening

  • Enables rapid, multi-depth assessment of cerebral blood flow velocity across the major conducting arteries.
  • Critical for diagnosing conditions like intracranial arterial stenosis, occlusion, and moyamoya disease.
  • Features M-mode synchronized spectral display for quick and accurate vessel location.
  • 2. Intracranial Pressure (ICP) Assessment & Cerebral Circulatory Arrest
  • Evaluates intracranial pressure by analyzing diastolic flow velocities and the resulting high-resistance spectral patterns.

Detects characteristic flow changes that indicate complete cerebral circulatory arrest, serving as a confirmatory tool in the diagnosis of brain death.

​​​​​​​Unmatched Clinical Advantages

  • Non-Invasive & Safe: No contrast agents, radiation, or invasive procedures are required, making it safe for repeated use across all patient populations, including pregnant women and children.
  • Cost-Effective & Fast: Provides a quick and affordable screening solution, with examinations typically completed in 15-30 minutes.
  • Portable & Bedside-Ready: Compact design enables seamless integration into any clinical setting, from outpatient clinics to intensive care units.
  • Real-Time Dynamic Monitoring: Unique ability to provide continuous, real-time hemodynamic data, crucial for tracking patient progress and guiding acute management.
