Rendering Ultrasonic Imagery: The Sonic Flashlight

Effugas writes: "Fark pointed me at this brilliantly elegant new invention, the Sonic Flashlight. From the curious workshop of George Stetten, an ultrasonic scan of the inside of a patient's body is visually overlaid perceptually within the body being scanned, with no requirement for special glasses, viewing angles, or even particularly exotic hardware. How? Form a triangle with an ultrasound platform and its output display--then bisect the triangle with a half transparent(see the body below), half reflective(see the display above) pane of glass. Since the angles match, the two images merge to provide a perfectly placed synthesis of reality and its augmentation, irrespective of viewer position. Watch the video here for a demonstration; note the hand held variant at the bottom of the page as well. Slick!"

There were reports that a suffciently young unborn child can hear the ultrasound, as seen by reactions in the womb.

Since these things are loud, it would sort of be the the equivalent of suddenly being in side a noisy train station. There has been concern expressed about possible damage

So while ultrasound is very cool, there are some times when it needs to be used with care.
