NEW

It provide you the recording of a new Doppler Ultrasound Audio data from the microphone input of sound card.

OPEN

It is used to open and analyse a previously recorded and saved in Windows PCM wave format Doppler Ultrasound Audio. Be careful that if the sampling rate is different than 22050 Hz, then your test will give wrong results.

SHOW INFO

The recording properties of format Doppler Ultrasound Audio are displayed on the form. Users can see the channel mode, sampling rate, bit per sample, number of samples and their total allocattion in bytes.

SHOW WAVE

The recorded Doppler Ultrasound Audio is displayed on the upper frame of the form. If the analyzing of Doppler Ultrasound Audio is completed, detected embolic portions are marked with a line on the waveform.

SHOW FILTERED

After application of band pass fitler and the TEO, resultant waveform is displayed in the lower frame.

TOOLS

APPLY FILTER

This tools is used to call the subroutine to fitler the raw data and apply the TEO to this filtered signal.

DETECT EMBOLI

In this tool, Embolus detection algorithm is applied to the processed data. If an embolus is catched, its location and relative duration is listed in the listbox at the right side of the form.

WRITE TO FILE

Detected embolc signals in the list box are witten into a text file. The name of the text file is the same with the name of sound wave file. This useful to archieve the result of a test.

ADVANCE/STANDARD

With this tool, you can switch between the Standard and advanced modes. In advance mode, user can set the test width and the coefficient of Standard deviation. Anytime, user can return to Standard mode.
