What about geeks who are developing rail guns, trying to make sense of genomic data, desiging buildings for a living, developing the next generation of low power processors........
I work with ultrasound imaging systems. There is a reason the brain is currently one of the organs that is not typically imaged with ultrasound. Bone significantly attenuates ultrasound and messes with the phase relationship between elements in the transducer array, so a) its tough to get enough signal in and out of the brain (while still staying withing FDA limits of what's acceptable), and b) its difficult to focus the beam to the area of the brain we are interested in. There are several research efforts to image the brain with ultrasound, and the approach taken is usually through the temple because the bone is thin there but the above problems still limit imaging ability. There are no easy fixes to these problems.
