SYSTEMS AND METHODS FOR CARDIOVASCULAR IMAGING, CARDIOVASCULAR FUNCTIONAL ANALYSIS, AND DETECTING CORONARY ARTERY DISEASE |
摘要 |
One aspect of the present invention relates to screening patients for an early stage of coronary artery disease. According to this method, a patient is screened based on the time-activity curve for a radioactive tracer passing through a left ventricle region of the patient's body. According to another aspect of the invention, an array of gamma particle detectors is employed to obtain data for a region of interest taht is larger than and encompasses a left ventricle region of the patient's body. An analysis of the data identifies the subset of the region of interest that corresponds to the left ventricle region. According to a further aspect of the present invention, a second technique is employed to locate the left ventricle region. A still further aspect of the present invention relates to high temporal resolution gamma cameras. |
