Line lasers are known from patient positioning, e.g. in a CT or for surgery.
For dental area application, line lasers are used to determine tooth and prostheses contours.
LEDs and lasers are also used in the medical part of research and development. When organic materials are illuminated with a certain wavelength, image recording systems can be used to perform an analysis of the resulting fluorescence.
In orthopaedics, lasers help to recognise malpositions and to initiate the respective medical correction.
