Abstract
Methods, systems, and computer readable media for taking measurements of a material, including determining material anisotropy, are provided. According to one aspect, a method for determining tissue anisotropy comprises: applying, to a tissue sample, a first force having a direction and having a coronal plane normal to the direction of the force, the first force having an oval or other profile with long and short axes within the coronal plane, the long axis being oriented in a first direction within the coronal plane, and measuring a first displacement of the tissue; applying, to the tissue sample, a second force, and measuring a second displacement of the tissue; and calculating a tissue elasticity anisotropy based on the measured first and second displacements. Furthermore, by applying the first and second forces multiple times, tissue viscosity, elasticity, or other anisotropy may be calculated from the multiple displacement measurements.
