Abstract

Generally, breast tumors are much stiffer than the surrounding tissue. The strain stress curves are common to the tissue characterization. Conventional system uses a dynamic and static deformation with controlled amplitude. In this work, we present a new deformation system which the displacement amplitude is dependent on the mechanical properties of the sample. This system is composed by a modified loudspeaker. A dedicated magnetic sensor is used to register the deformation amplitude. The variation in the load is also registered using a sensitivity load cell.
