Abstract: A palpation device for palpation of tissues for characterization (e.g., qualification and/or quantification) of subcutaneous structures is provided. The palpation device includes a frame formed from a substantially rigid material and comprising an opening; a tonometric lens extending through the opening of the frame; and a radiation source. The lens is configured to at least partially impinge a tissue of interest to identify an object embedded therein. The lens includes a body having a reflective coating on an outer surface thereof. The radiation source is positioned to illuminate the reflective coating such that a topography of the coating can be observed. The body includes a body material that is as stiff or stiffer than the tissue of interest and less stiff than the embedded object to be characterized. A system including the palpation device and an image device for obtaining an image through the lens is also provided.
