The present invention describes a furniture unit or a toy which employs base, top, and curved members along with a support member which extends along the inner surfaces of the top, base, and curved members. The frequency band is divided into a plurality of segment bands. Fixable to a fiducial location, the fiducial base may be attached in alignment to the registration frame. The sample receiving surface is preferably a circle, oval, square, rectangle, triangle, pentagon, hexagon, or octagon shape that is sized to hold a predetermined volume of the sample. The present invention thus provides a familiar image which may be used to facilitate review of a tomosynthesis data set.
