Ultrasound Doppler Systems For Examination of Peripferal And Transcranial Vessels

Detection and quantification of intra—or extracrania stenoses/occlusions
• Evaluation of intracranial circulation
• Evaluation of vertebrobasilar circulation
• Evaluation of ophtalmic artery flow
• Diagnosis of arteriovenous malformation
• Evaluation of haemodynamic reaction

Price: £ ???

Applications

The system is multifunctional diagnostic system, which is intended for

· CW Doppler examinations of the peripheral and extracranial vessels

· PW Doppler examinations of the intracranial vessels

· Culation examinations of uteroplacental blood flow circulation

 

.

· long time monitoring of transcranial vessels with automatic emboli detection

· monitoring ECG and Doppler signals simultaneously

· display trends of all Doppler parameters and indicies

                

 

Multiwindow screen layout

Report editor

Report editor allows to prepare quick report on the base of the report templates, which include:

· spectra of blood flow

· hospital name

· ID of patient

· index table

· date and time of examination ID of physician

Examinations

The following items are calculated automatically during examination:

· Blood flow curves

· Sistolic and diastolic marks

· Index tables for every heart cycle

· pulsation index for the brain structure pulsations

Spectrum and/or curves can be displayed in the spectral window. One of the two modes can be used to display spectrum from the data base:

o Cineloop with sound tracking

o Manual sliding under spectral buffer

                

 

A manual on Doppler examination of cerebral vessels. Software package includes build-in medical help (in hypertext format).

This medical help contains a series of normal and pathologic Doppler patterns which correspond of various states of the cerebral arterial bed. Each Doppler pattern is followed by description, diagnostic and therapy steps. Except pattern descriptions, medical help contains:

· Information about anatomy of the artery

· Method of it's location

· Protocol of the Doppler examination

 

Up to 10 windows can be displayed simultaneously on the screen. Flexible screen layout (from 1 to 10 windows) simplifies:

· carrying out examinations, especially in complex cases

· comparison spectra of left/right side vessels

· Comparison of the current examaination spectra and spectra

        from database

TEMPORARY SIGMATRON SITE

 

Additional software package is intended for long monitoring of transcranial vessels together with monitoring of ECG signal. Some features of software package are below:

· Automatic emboli detection with generating of histogram

· Trend window for all indices and parameters of blood flow

· Real time marking of different events during monitoring

· Generating event table for further data analysis

The one of the three data storage format can be seleted to save monitoring data (brief, middle, complete).
