DOI: 10.1109/jstqe.2018.2871596
Abstract: Compression optical coherence elastography forms images based on the mechanical properties of tissue by mapping the local strain in response to a compressive load. Strain is described by a second-order tensor, comprising six independent components.… read more here.
