<p><P>PROBLEM TO BE SOLVED: To provide a heart model for ultrasonic examination, having superior effects on the practical training of echocardiography. <P>SOLUTION: The heart model has one or more types of sections of an ultrasonographic tomogram comprising (1) a parasternal long axis tomogram; (2) a short-axis tomogram of aortic valve level; (3) a short-axis tomogram of mitral valve level; (4) and a short-axis tomogram of papillary muscle level. The heart model can be produced through a plastination process. Three coronary arteries of the heart model are colored in different colors, respectively. The components of the heart model can be made freely detachable. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
