Description

In this project, the student will start by generating a model of the healthy anterior visual pathway (up to and including the optical chiasm) based on available anatomical models that can be found in literature. In this pathway, the optic nerve and the nerve fibers should be modeled in two ways: first, a realistic 3D model should be designed and, second, an abstracted visual representation should be also provided and coupled to the first one.

Subsequently, the student needs to provide an interactive and flexible interface where a clinical expert is able to simulate lesions in the visual fiber tracts and explore their effect on the field of view of the patients (up to vision loss). This will be done based on available patient datasets and/or literature-based evidence, which covers extensively how the fibers run through the optical chiasm, as well as which fibers are responsible for losses in the visual field. In order to visualize this, well-established visual representations, commonly used in clinical practice will be employed, while novel ones might be required to be developed. The simulated effect should be bi-directional: (i) see the effect on the visual field, starting from a damage in the visual pathway and (ii) identify the location of the damage in the visual pathway, knowing the final losses on the visual field.

Tasks

  1. Create a dual (i.e., realistic and abstracted [1-3]) model for the healthy visual pathway.
  2. Visualize the simulated effect of lesions in the pathway bi-directionally (i.e., location of damage is known, what is the effect on the visual field and given a visual field, identify damage location).

Requirements

The final outcome should be a stand-alone application (environment to be discussed depending on the prior experience of the student). Additional knowledge of blender (or similar environment) would be advantageous. The student should have completed successfully at least one course on (Medical) Visualization and/or Computer Graphics. The project is done in collaboration with the Ophthalmology Department at the Medical University of Vienna.
