“Biomechanical imaging” refers to in vivo, or in some cases in situ, imaging
and measurement of mechanical property distributions in tissues. Doing so
requires the measurement of material (tissue) displacement via imaging,
the mathematical modeling of relevant tissue mechanics and deformation,
and subsequent inference of mechanical properties
through the solution of an appropriate inverse problem.
The papers below describe some work relevant to each of these aspects.
