Hi.
I have a vascular Doppler continous-wave flowmeter for
vascular investigations made by myself: this device run very
nice with a probe of 4MHz manifactured from a company of UT.
Now I'm searching to build by myself even the Doppler probe;
it's for one's own personal use because I must to have for my
study even probes of 1.5-2.5-3-5-8-10...MHz.
I don't want to buy all the series and I want to try to build
it by myself. For this purpose I have already some disk of PZT
at different frequency resonance (3-5-8 MHz) and I have already
tried to build this probe, but with minimum success: I have a bad
bad S/N.
I search bibliographics references about notes on construction
of these ultrasonic continous-wave doppler probes, but above all
the experience of someone already skill in the art.
Any type of help is very welcome.
Thank you in advance
Dr. Mauro Casaroli
