摘要：
A surgical system and corresponding methods for identifying tissue or vessels and assessing their conditions includes a probing signal source for applying a probing signal to the tissue and a response signal monitor for monitoring a response signal that varies according to the level of blood circulation in the tissue or vessels. The response signal monitor monitors the response signal over an interval equal to or longer than air interval between two successive cardiac contractions. The surgical system includes a microprocessor that analyzes the amplitude and/or phase of the response signal to determine the level of blood circulation in the tissue or in different portions of the tissue, and determines a tissue parameter based upon the level of blood circulation. The surgical system may monitor a cardiac signal related to cardiac contractions and correlate the response signal and the cardiac signal to determine a level of blood circulation in the tissue.
