Abstract
Systems and methods for transforming three-dimensional computed tomography (CT) data into two dimensional images are provided. Such a method is provided including retrieving three-dimensional CT imaging data, where the three-dimensional CT imaging data comprises projection data acquired from a plurality of angles about a central axis. Once the three-dimensional CT imaging data is retrieved, the imaging data is processed as a three-dimensional image and the method proceeds to generate a two-dimensional image by tracing rays from a simulated radiation source outside of the three-dimensional image. The two-dimensional image is then presented to a user as a simulated X-Ray.
