    摘要: Systems and methods are provided for imaging of soft and hard tissues with ultrasound. Such systems and methods can provide for non-contact and quantitative ultrasound images of bone and soft tissue. A method for imaging a biological body segment of soft and hard tissues includes setting geometry and material properties according to a model of the biological body segment to thereby generate a simulated time series data set. The method further includes collecting reflective and transmissive time series data of the biological body segment to thereby form an experimental time series data set and minimizing a difference between the simulated time series data set and the experimental time series data set, thereby imaging the biological body segment. Regularizing travel-time and/or using full waveform tomographic techniques with level set methods enable recovery of cortical bone geometry.

    摘要: A signal sensing module includes a substrate, a sensing electrode, a piezoresistive material layer and a sensing circuit. The substrate has a surface. The sensing electrode is disposed on the substrate and is exposed from the surface. The piezoresistive material layer is formed on the surface and covers the sensing electrode. The piezoresistive material layer has a resistance value. The sensing circuit is disposed in the substrate and adapted to sense a change of resistance value when a pressure wave passes through the piezoresistive material layer.
