You can get the current slice image from the slice logic of the slice widget at shown in this example . However, probably you can get the ideal pedicle screw axis position and orientation directly in 3D by segmenting a pedicle. It can be as simple as Paint a sphere with “Editable intensity range” se…

[image] Centroid determination import numpy as np print(np.average(array('ModelX'), axis=0)) 老师您的意思👆🏻是说，多边形各顶点坐标的`np.average()'就是这个多边形的质心吗？ Teacher, do you mean :point_up_2:t2: that the `np.average()’ of the coordinates of each vertex of the polygon is the centroid of the polygon?

well,现在的问题就转化成了如何提取当前界面某个多边形的顶点坐标。。。 Well, the current question now becomes how to extract the vertex coordinates of a polygon of the current section. . .

[image] jumbojing: Due to some special cases such as osteoporosis, segmenting a pedicle with script is not always ideal. Yes, I know that segmentation of the pedicle is often not trivial, but there are many Segment Editor tools that can help with this. You could also train a neural network us…

I want to weight the centroid obtained above by the reciprocal of voxel (CT value), how to do it?
