[–] IshKebab 10d ago ↗ You still need a section of skull removed though.Also having done a PhD on ultrasonic imaging I'm a bit skeptical of their claims. Ultrasound is a pretty shoddy imaging technology really. [–] daymanstep 10d ago ↗ Yeah ultrasound sucks. I have an ultrasound distance measurer and it thinks a 1.8 meter gap is 0.6 meters. Extremely inaccurate. [–] Klayy 10d ago ↗ to be fair car parking sensors are ultrasound and they are definitely not THAT inaccurate. Maybe your meter is broken
