摘要

The two dimensional (2D) microwave tomographic system has been constructed. The cross sectional static and dynamic images of the canine explanted heart have been reconstructed. It is our hypothesis that microwave spectroscopy (multifrequency probing) is a sensitive indicator of myocardial ischemia and infarction. The specific aim of this investigation is to evaluate our hypothesis and quantify the changes in the dielectric properties of the myocardium as a function of the degree of ischemia and infarction. Various experiments were conducted using canine: 100% left anterior descending coronary artery (LAD) long time occlusion, 100% LAD short time occlusion/reperfusion sequence, partial LAD flow reduction, chronic myocardium infarction (MI) (5 days, 2 weeks, 5 months). It has been experimentally proven that microwave spectroscopy is a sensitive indicator of the myocardial ischemia and infarction.
