    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.

      Yeah ultrasound sucks. I have an ultrasound distance measurer and it thinks a 1.8 meter gap is 0.6 meters. Extremely inaccurate.

        to be fair car parking sensors are ultrasound and they are definitely not THAT inaccurate. Maybe your meter is broken
