Although cell suspensions, such as blood, are currently preserved through freezing techniques: successful cryopreservation has not been performed on entire organs. This is due in part to the difficulty in maintaining uniform cooling rates throughout a bulk sample. In this work, an optimization procedure was used to determine numerically the proper surface thermal conditions in order to maximize local survival throughout the interior of the entire bulk system. The feasibility of using such a procedure for cryopreservation processes and the limitations of such a procedure are discussed.
