Abstract
The machine perfusion (MP) technique can expand the donor pool for organ transplantation. The MP technique is able to not only supply the organ with nutrition and oxygen continually through the preservation solution but also evaluate the liver viability. However, the perfusion machine that can evaluate liver viability is not yet established. In this study, the new evaluation technique using temperature visualization technique is suggested using porcine donated livers. This technique is visualized temperature distributions using temperature difference between preservation solution and the livers, and the temperature difference distribution in the liver can estimate flow condition in vessels. As a result, the temperature difference distribution in the liver and the transitions of the temperature at each measurement points can indicate the visualization of flow condition in vessels and liver viability at each point before implantation.
