The images for this assignment are chest CT images acquired using vascular contrast.  For the last part of this assignment, you will segment the 3D vasculature, including ascending aorta and pulmonary vessels, etc.  A basic anatomy diagram is available here:

You will start the assignment with a small cropped-out volume that contains mostly just a piece of the ascending aorta.  After working with a 2D slice through the small volume and then the small 3D volume, you will proceed to the main assignment of the entire 3D chest CT w/ contrast.  Note that for the full-size volume, it is possible to obtain a better segmentation than the reference provided in ChestCT_VascularSeg.mha.

Image Files, Reference Segmentations, and Seed Points:

Full 3D Volume:
ChestCT_VascularContrast.mha
ChestCT_VascularSeg.mha (note:  it is possible to do better than this reference)
A seed point that can be used for the segmentation is (113,58,53), but you may be able to find better seed point(s)

Small volume cropped to contain a piece of the ascending aorta (64x64x64 voxels):
AscendingAortaCrop.mha
AscendingAortaCropSeg.mha
Use initial seed (35,17,28)

2-dimensional image obtained by exporting one slice from AscendingAortaCrop.mha
AscendingAorta_2D.png (also in .nii format)
AscendingAorta_2DSeg.png (also in .nii format)
Use initial seed (35,34)
