A simple-to-use, noninvasive, and risk-free system, which will provide accurate identification of potentially life threatening malignant tumors using tactile pressure, is developed. The Smartphone-based Compression-Induced (SCI) Scope will allow physicians to quickly capture the mechanical properties of a benign or malignant tumor with the convenience of a smartphone platform. The size and elasticity property is described using estimating methods from the pressure-induced images of SCI Scope. The device is based on the Apple iPhone 6. The image will be captured through a waveguide. The image information in combination with the force sensor value will be transmitted wirelessly to a computer for processing. The size and elasticity estimation experiments with SCI Scope showed that the size estimation error of 2.31% and estimated relative elastic modulus error of 23.9%.
