Abstract
Abstract The invention is a specimen support comprising a specimen board with an absorbent square attached thereto, radio-opaque indicia attached to the specimen board, a compression sheet hingedly attached to the specimen board and means for attaching the board and sheet together at a location remote from the hinge. The apparatus may be used for radiographically localizing internal structure of a specimen carried by the board.
