Ray casting with on-the-fly region growing: 3-D navigation into cardiac MSCT volume

摘要

We describe an extended ray casting scheme for 3-D navigation into the heart cavities for pre-operative planning using multislice X-Ray Computed Tomography data. The key benefit is that artifacts due to contrast inhomogeneities can be eliminated during volume traversal, thus improving the visual perception of the endocardial wall.
