Title: Wireless perfusion imaging to assist plastic surgeons
during free flap breast reconstruction


We aim to assist plastic surgeons evaluate viability of a transplanted breast tissue in order to prevent complications in a deep inferior epigastric perforators (DIEP) flap surgery after removal of breast cancer. To do so, we have developed a wireless laser speckle contrast imaging (LSCI) device suitable for use in operation room. LSCI is a non-contact method for objective assessment of skin perfusion. It is a promising approach for intraoperative applications in that it does not require any contrast agent and can be implemented in compact size and with affordable price. Such advantages make LSCI a potential alternative to the existing fluorescent imaging devices that are not only costly and bulky but also require injection of contrast agents on a regular basis.
