摘要： A method and an apparatus for preoperative identification of a perforator vessel for plastic and/or reconstructive surgery using ICG fluorescence angiography imaging are disclosed. Time-resolved image processing is used to highlight perforator locations and to enable visual discrimination among candidate perforators by various computed metrics Based on these metrics, the surgeon is able to interactively locate and select perforator vessels suitable for plastic and reconstructive surgery

摘要： Vessel perfusion and myocardial blush are determined by analyzing fluorescence signals obtained in a static region-of-interest (ROI) in a collection of fluorescence images of myocardial tissue. The blush value is determined from the total intensity of the intensity values of image elements located within the smallest contiguous range of image intensity values containing a predefined fraction of a total measured image intensity of all image elements within the ROI. Vessel (arterial) peak intensity is determined from image elements located within the ROI that have the smallest contiguous range of highest measured image intensity values and contain a predefined fraction of a total measured image intensity of all image elements within the ROI. Also disclosed is a method for tracking a moving blood vessel to aid in assessing peak vessel intensity over time. Improvement in cardiac function can be established by comparing the time differential between the time of peak intensity in a blood vessel and that in a region of neighboring myocardial tissue both pre and post procedure.
摘要翻译：通过分析在心肌组织的荧光图像的集合中在静态感兴趣区域（ROI）中获得的荧光信号来确定血管灌注和心肌腮红。腮红值是从图像元素的强度值的总强度确定的，该图像元素位于包含ROI内的所有图像元素的总测量图像强度的预定分数的图像强度值的最小连续范围内。血管（动脉）峰强度由位于ROI内的图像元素确定，该图像元素具有最高测量图像强度值的最小相邻范围，并且包含ROI内所有图像元素的总测量图像强度的预定分数。还公开了一种用于跟踪移动血管以辅助评估峰值血管强度随时间的方法。可以通过比较血管中峰值强度与前期和手术后相邻心肌组织区域时间的时间差来建立心脏功能的改善。
