Ultrasound Visualization With the Sonic Flashlight
The Sonic Flashlight uses a half-silvered mirror to merge
direct views of an object with an ultrasound scan of the
object's interior. It provides an independent illusion
of a 2D cross-section through a 3D object, without relying
on head tracking or virtual-reality glasses.
Innovation
Multi-person augmented-reality device in a handheld display.
Vision
Current clinical use of ultrasound requires the physician
to look away from the work area (patient) in order to
view the ultrasound image. This is particularly undesirable
when using ultrasound to guide invasive procedures, such
as needle biopsy or catheter placement. The Sonic Flashlight
allows in situ visualization of real-time ultrasound images
without expensive or cumbersome hardware, and thus has
the potential to greatly improve the accuracy and ergonomics
of ultrasound-guided medical procedures. Future research
will address calibration routines, further miniaturization
of device components, clinical trials, and exploration
of additional medical applications.
