17.7 A 7.0fps Optical and Electrical Dual Tomographic Imaging SoC for Skin-Disease Diagnosis System

Recently, skin disease patients have been rising rapidly, and more than 5.4 million cases of skin cancer were treated in over 3.3 million people in the U.S. in 2012, and more people are diagnosed with skin cancer each year than all other cancers combined in the U.S. [1]. Because a malignant lesion is difficult to distinguish from pigmented nevus, elaborate detection devices are needed for accurate diagnosis [2]. Optical Coherence Tomography and Laminar Optical Tomography are mainly used for skin disease diagnosis, however, equipment for those tomography are too bulky to be used in house. The Electrical Impedance Spectroscopy is also applied to analyze skin disorders [3], but its equipment requires assistance from experts.
