In heart surgery with extracorporeal circulation machine, myocardium becomes hard when myocardial preservation is not appropriate. Myocardial hardness measurement probe has been developed for quantitative hardness monitoring measurement for myocardial preservation. To measure myocardial hardness negative pressure is applied to the myocardium through the probe and displacement of myocardial surface is measured using ultrasonic pulse-echo. Using two silicone rubbers which have different hardness, we applied the same strength negative pressure to their surfaces. We measured the displacement of two silicone rubbers.
