armcrop 0.4.1

A machine learning model that crops CT scans to a bone of interest in the arm

armcrop

This package contains a machine learning model that can crop a CT scan to any of the following classes:

• clavicle
• scapula
• humerus
• radius_ulna
• hand

It can do both axis aligned cropping and oriented bounding box (obb) cropping. The obb cropping allows for rigid registration of CT scans.

This model was trained on arm only scans and proximal half chest scans. A limitation of this model is that when using a full chest CT where the spine is present the model will struggle to differentiate between it and the scapula.

Installation

To use CPU execution install with:

pip install armcrop

To use CUDA execution you will need to also install torch and onnxruntime-gpu.
