Novel Ultrasound Imaging Applications
摘要
Routine applications of ultrasoundUltrasound imagingImaging combine arrayArray technology and beamforming (BF) algorithms for image formation. Although BF is very robust, it discards a significant proportion of the information encoded in ultrasonic signals. Therefore, BF can reconstruct some of the geometrical features of an object but with limited resolutionResolution due to the diffraction limitDiffraction limit. Inverse scatteringInverse scattering theory offers an alternative approach to BF imagingImaging that has the potential to break the diffraction limitDiffraction limit and extract quantitative information about the mechanical properties of the object. High-resolutionResolution, quantitative imagingImaging is central to modern diagnostic technology to achieve cost-effective detection through high sensitivity and limited false positive rate. This chapter lays out a framework encompassing theoretical and experimental results, and in which inverse scatteringInverse scattering and modern arrayArray technology can be combined together to achieve super-resolutionResolution, quantitative imagingImaging.
