CA 2444413

This invention is a process and a method to visually identify and delineate, areas of interest or utility in samples for medical, biological or other natural scientific reasons, by observing fluorescence, autofluorescence, phosphorescence and the like, excited in the sample by violet laser light. Imaging is accomplished by using a special filter matched to exclude the laser wavelength. The new technology of violet laser diodes is used in order to produce a lightweight, low power, portable, device which permits real time observation of medical and other natural subjects at an economical cost. More especially, said invention relates to the use of such a device to visually identify and delineate breast cancer in vivo, during surgery or in a pathology laboratory.
