From Puget Sound Business Journal:
S-Ray Inc. is developing its low-cost 3D imaging system with a patented ultrasound technology. The S-Ray system connects to a laptop or tablet and does everything an X-ray does using a simple mouthpiece that scans the teeth with ultrasound sensors rather than radiation and “bitewings” disliked by many patients.
I have been following S-Ray with interest and with skepticism. I love the concept and the potential applications. However so far there has been a lot of what if and not much actual movement in the market. This article indicates the company is still growing, reaching financial objectives and ready to move to a higher level. I wish them success.
S-Ray is an ultrasonic device specifically designed for dentistry. Ultrasound measures differences in tissue density. This includes the difference in soft tissue, bone and crevicular fluid. In theory S-Ray could detect and measure all the gingival pockets around all the teeth in a simple ten second scan. The pockets could be displayed as a 3D model and as a table with the depths shown in mm.
The S-Ray device could also be used to create study models, detect decay and bone loss.
