Can anyone provide a recommendation as to which medical ultrasound device allows to RAW RF data in PWD mode?
The most common example I see give access to RAW data in B-mode. But I'm are specifically interested in the blood velocity.
Hie though am not really sure about your question but when it comes to blood velocity I think we interpret the Doppler shifts amplitude displayed on the PSD graph.
Not sure I answered you correctly dear
Thanks, I'm looking for the signal that is used to generate the PSD graph.
The Vevo2100 and Vevo3100 from FUJIFILM-Visualsonics can export IQ or RF data. It requires a license for the RF-mode package (for IQ storage), and access to the engineering mode to be able to do the export.
I haven't tried myself in PWD mode, so you might want to contact them about this specifically, but it works for me for other modes (B-mode, Contrast Mode, PA mode).
Hello Emmanuel Cherin , I contacted FujiFilm.
They are very pleasant to talk to. Noticed a couple things.
1. These are high frequency devices.
2. They are animal imaging systems.
We don't need high frequency for basic vascular imaging of large arteries.
We are doing human research.
With that said, their machines can still use low frequency probes. Given that our application is not clinical diagnostic but pure research, we will have to work with our Ethics to work out how to make use of the device.

Hello Emmanuel Cherin ,
I spoke with FujiFilm, and here is what they tell me:
"(It's not possible to capture Pulsed-Wave Doppler data in RF mode on any of our systems.)"
It's unfortunate.
I'll keep looking.
Yeah, I was somewhat suspecting that for PWD it would be challenging as it would require quite a bit of buffer memory to capture the RF associated with a drastically increased number of transmit events.
As you mentioned, VS latest scanner (F2) can accommodate at least one lower frequency probe (L38xp) which is covering the let say 4-12 MHz frequency range.
In any case, good luck with your search.
