BACKGROUND AND OBJECTIVES: We report on a study to investigate feasibility of utilizing ultrasound imaging to guide laser removal of subcutaneous fat. Ultrasound imaging can be used to identify the tissue composition and to monitor the temperature increase in response to laser irradiation. STUDY DESIGN/ MATERIALS AND METHODS: Laser heating was performed on ex vivo porcine subcutaneous fat through the overlying skin using a continuous wave laser operating at 1,210 nm optical wavelength. Ultrasound images were recorded using a 10 MHz linear array-based ultrasound imaging system. RESULTS: Ultrasound imaging was utilized to differentiate between water-based and lipid-based regions within the porcine tissue and to identify the dermis-fat junction. Temperature maps during the laser exposure in the skin and fatty tissue layers were computed. CONCLUSIONS: Results of our study demonstrate the potential of using ultrasound imaging to guide laser fat removal. (c) 2008 Wiley-Liss, Inc.
