The current surgical procedure for breast diseases places an emphasis on the conservation of breast skin in order to provide more optimal reconstruction.

The purpose of this study is to use portable, non-contact optical imaging device developed at the Beckman Laser Institute called Spatial Frequency Domain Imaging to detect the changes in a skin during reconstructive surgery procedure and healing process.

The researchers can use Spatial Frequency Domain Imaging instrument to measure the concentration of blood flow in the skin tissue and can determine of the changes that observed in the properties of the mastectomy flap that may be delay in healing process.

The imaging device can determine the change from baseline measurement to the development of skin necrosis, wound infection, or implant extrusion.

Inclusion Criteria:

• Adult male and female 18 years and older scheduled for breast reconstructive surgery.

Exclusion Criteria:

• Minor and pregnant women

Study Population will be recruited from UCI Anesthetic and Plastic Surgery Institute clinics, seen by the Plastic Surgery Service. Subjects requiring breast reconstructive surgery using either implant based or autologous reconstruction will be identified.
