Open Source Development
Here you will find resources for the open source development of an ultrasonic imaging application/API based on USB ultrasound probes that are commercially available.
The specifications for this project are found here. These are somewhat fluid at this point so don't bank on anything, yet.
Here are some items that will be of use as this project gets underway. All downloads in this section will require a password and that password will only be given to students in the class who are currently working on this project (so don't ask if you are not in that class).
