Non-destructive testing and imaging ultrasound modalities have been around since the ’50s. More and more ultrasound-based initiative are emerging, mostly focusing on image processing - while the hardware has been left behind. Several teams have produced successful designs for the different possible uses, mostly efforts from research laboratories. Most have been used on commercial US scanners, traditionally used as experiment platforms, but they are not cheap, and yield very little in terms of data access and control. Others have been developed in labs, but, sadly, very few have been open-sourced. This particular project stems from a previous Beaglebone-based design, as well as an Arduino-like module-based design.
It has also been shown that simple (be it low-power, low-cost and small) can be achieved - and this, even for relatively complex systems, based on 16 to 64 parallel channels front-end processing and software back-end processing (embedded PC or DSP). This makes it a bit more complex for the layman, hobbyist, or non-specialist researcher to use, not to mention the very little information that is accessible.
Previous work
This element has been built as part of a kit, which is composed of :
Headers are not included! (nor is the RPi W)
Overall description
What does it look like?
Why did you make it?
Nothing existed yet!
What makes it special?
Nothing similar had been done so far with open source FPGA for high-quality processing.
Example of acquisitions
Example of a single line for a couple of cm echoes.
The green line is TGC, the blue line is the signal.
Corresponding signal
Example of a 2D image
The whole repo is on github.
Documentation
Full documentation is on doc.un0rick.cc
With some detailed specs, or example of an acquisition.

Shipping
- Now that the board design is stabilized, it's being produced by MacroFab - which does the fulfillment.
- Attention: The board comes without headers/jumpers/RPi .. up to you to put yours!
