Where can I obtain Pixel-wise Displacement in ultrasound images? #1

Where can I obtain Pixel-wise Displacement in ultrasound images? I want to obtain the deformation of soft tissue in ultrasound images and quantitatively describe the deformation of breast tissue under certain contact forces. May I ask if the method you proposed can solve this problem? Thank you very much for sharing!

If it can be obtained, how can I run the program to obtain it? Can you provide detailed instructions on the steps? thanks

Hi, we use RAFT [https://arxiv.org/abs/2003.12039] for the dense deformation field estimation. Since it utilize optical flow estimation therefore we need to give 2 images as input for estimating the deformation.

In my reop, you can go to raft folder, I write script generate_gt.py to get the deformation field for my customized dataset.

I would also recommend you use the official repo https://github.com/princeton-vl/RAFT for the deformation acquisition.

Hope it helps you!
