Hi, guys:

I am looking for high frequency Medical Ultrasonic Imaging system analog and RF circuit design, simulation and test stuff. For example:

Receiver, transmitter, oscillator, Tx Pulser, Analog Beam Former, analog wall high pass filter, multiplexer, CW and PW Doppler System circuit, power supply.

Would anyone share articles, tutorials, E-books, web site link, or recommend me buy some books that focus on ultrasound analog circuit design?

Thanks in advance,

ywyw

Hi,

Thanks for reply.

Before I posted this message, I had already read this article. This article just gives a general ideal, actually it just mentions how to select components of Analog Devices Inc., and it has nothing to do with circuit design and simulation. Thanks anyway.

I am interested in not only selecting components but also designing and simulation and test circuits. For example, what is the best circuit type of transmitter of commercial medical ultrasound imagining system? RF class E power amp? Or RF class F power amp? Or RF linear amp? Or designer can just use some kind of operational amp because frequency is low (20 MHz or so)? Can anyone (experience engineer) explain this question?

:oops:


best regards

Hi,

I am sorry for my question is not clear enough. Let me re-ask again.

We know in medical ultrasound imagining system, transmitter includes a TX pulser (pulser works in switch status) and amplifier. Amplifier excites pulser, and then pulser excites transducer to produce ultrasound.

My question is what is the best circuit type of amplifier that excites the pulser? RF class E power amp? Or RF class F power amp? Or RF linear amp? Or designer can just use some kind of operational amp because frequency is low (20 MHz or so)? Could anyone (experience engineer) explain this question?

Best Regards,

ywyw
