Un0rick: Open-source pulse echo ultrasound

- Un0rick is an open-source, low-cost ultrasound platform that makes medical imaging more accessible, especially in low-resource settings. It uses standard "pulse echo" ultrasound principles but runs on off-the-shelf electronics and open-source software. - Commercial ultrasound machines are proprietary and expensive ($10k–$100k+), limiting research, education, and clinical use in the developing world. Un0rick provides a fully open hardware/software stack anyone can build or modify. - Created by researchers in the open-source imaging movement, it's used in academic research and DIY medical device communities. - It enables experimentation with new imaging techniques and machine learning, but requires technical skill to assemble and lacks regulatory clearance (FDA/CE) for clinical diagnosis — making it a research/education tool, not a certified medical device replacement.
