In order to identify the exact location of the useful perforator for DIEP flap breast reconstruction, CT images are made in the pre-operative phase. The aim of this research is to check and visualize the blood flow in the flap by means of infrared thermography. In addition, infrared thermography will be applied during and post-operative phase. The results will be used in order to pinpoint the usefulness of IR thermography as an alternative for perforator mapping. The thermal images will help to decide which parts of the flap can or cannot be used for the DIEP flap reconstruction. By means of infrared thermography a blood vessel distribution of the abdominal wall will be visualized.
