Abstract: An apparatus and method for faster pathology are provided that removes the need for time consuming preparation of a hardened tissue block. Such hardening is necessary to enable cutting of the thin tissue sections required for pathology evaluation. Rather the tissue specimen is hardened by freezing only at the surface from which tissue is to be sectioned by contact with a cold surface or slide thereby lessening the time required for hardening. Sectioning is performed by passing a cutting device such as a blade, cutting wire or laser beam along a plane parallel to the cold surface and using the cold surface as a guide.
