When looking at something in minute detail a microscope is a vital tool.
And it can be equally vital in medical examinations if we are to detect cellular changes as early as possible.
A research team from the University of Nottingham has developed a special ultrasound system. One that is so tiny it can be deployed on a hair-thin fiber.
Its size means the damage to surrounding tissue in the body is minimal. And the use of contrast agents can also be reduced.
The mini ultrasound uses lasers to send impulses. This creates a sound wave, which provides 3D information on the state and form of the tissue under examination.
The technology is still under development. Watch this space.
