摘要:
A method and computer program are provided for segmenting a prostate from a medical image such as an ultrasound image. Each slice in a study is analysed and uses a manual initialization to obtain an initial contour, in which a user selects initial points that are automatically rendered on the image. An automatic refinement stage then snaps the contour to the prostate boundary in the image based on a pre-stored anatomical atlas and edge information obtained from the image. A manual adjustment stage may then be performed and if selected, the contour is automatically propagated to the next image slice to avoid the manual initialization. An auxiliary image slice may be referred to, which indicates how the prostate shape changes from slice to slice, e.g. by providing a perpendicular profile.
摘要(中):
提供了一种用于从诸如超声图像的医学图像分割前列腺的方法和计算机程序。 分析研究中的每个切片,并使用手动初始化来获取初始轮廓,其中用户选择自动呈现在图像上的初始点。 然后,自动细化阶段基于从图像获得的预先存储的解剖图谱和边缘信息将轮廓锁定到图像中的前列腺边界。 然后可以执行手动调整阶段,如果选择,轮廓将自动传播到下一个图像切片,以避免手动初始化。 可以参考辅助图像切片,其指示前列腺形状如何从切片切换到切片。 通过提供垂直轮廓。
