提出了一种基于图搜索原理的自动边界检测方法。该方法考虑到在生物医学应用中通常可用的图像的时间或空间序列中可用的附加信息。该方法被应用于检测心脏的短轴磁共振图像中的心内膜和心外膜边界。初步结果表明，与仅基于单个图像数据的方法相比，该方法在噪声区域中可能更鲁棒。他们认为，这种方法可以潜在地提高性能的自动边缘检测方法时，帧的空间或时间序列是可用的。<<ETX>>
Developed is a new method of automated border detection using graph searching principles. The method takes into account the added information available in temporal or spatial sequences of images that are commonly available in biomedical applications. This method is applied to detect endocardial and epicardial borders in short-axis magnetic resonance images of the heart. Preliminary results show that it may be more robust in areas of noise when compared to a method based only on data from a single image. They suggest that this method could potentially improve performance of automated edge detection methods when spatial or temporal sequences of frames are available.<<ETX>>
