Optical imaging technology in minimally invasive surgery - Current status and future directions

Optical engineering and imaging technology have played a major role in the evolving field of minimally invasive surgery (MIS) by making it possible to visualize the manipulation of tissue at remote internal sites. We assess a nd review the optical imaging technology used during a variety of MIS proce dures from an engineering perspective. The field of MIS is evolving rapidly . Optic-based technologies have the potential to further improve diagnostic capabilities of MIS. Optical imaging technologies and instrument designs a re discussed in relation to their current and future use in MIS procedures. Technical limitations in imaging technology are described, along with pote ntial solutions. We review the current status and future role of optical im aging technology in MIS. In the future, synergistic benefits from engineeri ng, imaging technology, and MIS are likely to improve diagnostic ability an d patient care.
