ABSTRACT:
An improved tissue imaging system is provided, in which tissue can be sheared without direct manual manipulation, so that different perspective images of the tissue can be determined, preferably in a single compression cycle. In one aspect of the invention, a traction system is provided, comprising at least a layer of a radiolucent material dimensioned and constructed such that the layer can pass between tissue and a surface of a tissue imaging device. The radiolucent material has sufficient tensile strength that the layer can slide without tearing against the surface of the tissue imaging device when tension is exerted on the layer, the sliding resulting in movement of the tissue relative to the surface of the tissue imaging device. A method of moving tissue relative to at least one surface of a tissue imaging device is also provided.
