Objective

• We are interested in segmenting the eye ball, lens, optic nerve, and the optic chiasm.
• Anatomical structures are highly sensitive to radiation.
• We are creating a framework to perform these segmentations, which is likely to require a different approach for each structures due to the proximity of multiple structures to each other.

Approach

• Pivotal organ is considered the eye since its segmentation will localize the region of interest when looking for other structures.
• We will reduce the dimensionality of this problem by performing model based segmentation for each structure.
• Once the eye is segmented, we use this knowledge to locate the lens/ initialize optic nerve segmentation.
• We would like to leverage the information provided by a CT scan with additional data from an MRI -- we have to consider this registration problem.

Progress

• We have the eye ball segmentation.
