Researchers have shown that existing optical fibre technology could be used to produce microscopic 3-D images of tissue inside the body, paving the way towards 3-D optical biopsies.
Unlike normal biopsies where tissue is harvested and sent off to a lab for analysis, optical biopsies enable clinicians to examine living tissue within the body in real-time.
This minimally-invasive approach uses ultra-thin microendoscopes to peer inside the body for diagnosis or during surgery, but normally produces only two-dimensional images.
Research led by RMIT University in Melbourne, Australia, has now revealed the 3-D potential of the existing microendoscope technology.
