I’m working on an imaging fusion project that combines a small-FOV image with finer details and a large-FOV image with better description of surrounding anatomical structures.
To evaluate the performance ( reproducibility), I did the following:
- Add two scalar volumes after a rigid transform of one volume while keeping one fixed to get a fused image(volume)
- Intensity based segmentation A of the fused image(volume)
- Repeat step 1-2 to get the second segmentation B.
- Calculate the image metric with Hausdorff and DICE.
Here is the question. I noticed that both mean and maximum of Hausdorff distance values are reasonable but 95% is 0. I wonder if it’s something I am doing is not correct or that’s what I should expect? I came across a previous post mentioning the 95% could be 0.
Thank you for your time and help in advance.
