| Abstract: | The theoretic model of transmyocardial laser revascularization is established and the quantificational relationship among vessel aperture,laser power and irradiation time is concluded according to the law of interaction of infrared laser with myocardium and the thermodynamics.The experiment of carbon dioxide laser revascularization in pig myocardium is done with different laser power and irradiation time.The error between the experimental result and the theoretical analysis is between 13% and 22%.The reason... |
