1. A compression assembly for imaging biological tissue, the compression assembly for use with imaging apparatus that provides a visualization of an internal structure of the biological tissue, the compression assembly comprising:

  • a fixed compression surface having a fixed first proximal edge;

    a second compression surface having a second proximal edge;

    means for positioning the first compression surface substantially opposite and spaced apart from the second compression surface to define an imaging field, the means for positioning including means for moving the first compression surface relative to the second compression surface so that the first proximal edge moves rearwardly of the second proximal edge when the first compression surface is moved towards the second compression surface,thereby inducing traction in a biological tissue when partially inserted between the first compression surface and the second compression surface, the traction assisting in drawing the internal structure of the biological tissue within the imaging field.
