Method for identifying time step of state of organ with periodic contraction and relaxation and ultrasound diagnostic apparatus using the same

摘要

The ultrasound diagnostic apparatus according to the present invention, which is used to examine the function of the heart based on the ultrasound image sampled in the contraction period and relaxation period of the heart, comprises: means for sampling an ultrasound image of the heart, means for obtaining an ecological signal from the heart, Means for storing ecological signals and ultrasound image data, means for automatically identifying the examination time point as the contraction and relaxation period of the heart based on the ecological signal read out from the memory means, the ultrasound image and time phase sampled at this time point Means for analyzing heart function based on the identification result.
