This repository includes 10 numerical models of axillary regions of 5 patients obtained from breast Magnetic Resonance Imaging (MRI) scans. The purpose of this repository is to provide models to the research community, which can be used for the development and/or validation of new electromagnetic systems for diagnosis or treatment of axillary region or other diseases in the torso, including the diagnosis of Axillary Lymph Nodes (ALNs).
Each axillary region model includes a maximum of 6 tissue types: adipose tissue, muscle and fibroglandular tissue, skin, lung, healthy ALNs and metastasised ALNs.
All files are provided in MAT, RAW and STL formats. The files were created with the original resolution of the MRI scans. Post-processing steps such as interpolation or smoothing filters might be needed to fit the electromagnetic simulation software requirements. The STL files were not validated for 3D-printing. Two additional files for adipose and skin without cavities are provided in STL format to allow the user to combine post-processing STL files.
