It is Doppler ultrasound analyzer of blood flow for bilateral transcranial monitoring, automatic detection of embolism and regular examination (transcranial, extracranial and peripheral).

Angiodin-2К is created to address a wide range of issues of transcranial Doppler monitoring with automatic detection of microemboli and building of histograms of their distribution in real-time mode.

Angiodin-2К meets all the requirements for Doppler expert class systems, used for monitoring of blood flow in blood-vessel and neurological surgery, emergency neurology and intensive care units.

Simple, convenient and efficient are all modes of reproduction, recording, processing and storing of arterial blood-pressure trends, cerebral blood flow and audio-signals, synchronized in time.
The device possesses developed system of customization of user interface, creation, editing of algorithms for carrying out of functional tests and mathematic profiles for data processing.
There envisaged possibilities of expert assessment of examination results in the mode of synchronic spectrogram and audiogram reproduction of any trend area.
Inbuilt utilities allow to archive monitoring data to PC disk and/or to external media of DVD format, to export results to MS Woгd, Excel and support data exchange in local networks.

Example of automatic detection of microembolismUse:

  • Detection of quality and quantity characteristics of cerebral microembolism.
  • Assessment of quality and quantity parameters of blood flow during tectonic coronary, carotic and peripheral arteries surgery.
  • Doppler transcranial ultrasound of vascular system (quantity and quality assessment of changes in cerebral hemodynamics in the course of cerebrovascular diseases).
  • Initial examination of patients with acute cerebral ischemia (early detection of stroke subtype for acute ischemia patients).
  • TDG (USDG) is monitoring of cerebral arteries patency during acute stroke.
  • TDG (USDG) is monitoring during acute stroke period for detection of need for emergency therapeutic or surgical interventions.
