An engineer
has invented a device which lets doctors 'see' through a patient's
skin and into their body.
It uses ultrasound
to scan the organ and then the image is projected on to a see-through
moveable mirror held over it.
By looking through
the half-mirrored surface, the doctor appears to see the patient's
insides floating within their body.
The so-called
sonic flashlight shows blood vessels, muscle tissue and other internal
organs exactly as they would appear if the skin surrounding them
was translucent.
It was developed
by George Stretten, an assistant professor of bioengineering at
the University of Pittsburgh.
He was inspired
by finding current ultrasound devices clumsy because an operating
surgeon has to keep looking away from the patient at a TV screen.
A study on the
device was published in the Journal of Ultrasound in Medicine and
reported in Whitaker News.
