Title
Medical applications of example-based super-resolution
Summary
Example-based super-resolution (EBSR) reconstructs a high-resolution image from a low-resolution image, given a training set of high-resolution images. In this project I plan to implement some applications of EBSR to medical imaging. A particular interesting application, which I call "x-ray voxelization", approximates the result of a CT scan from an x-ray image. This is useful for reducing radiation dose received by patients and can dramatically improve dose-controlled precision.
Aims
In the CT arm of NLST, we plan to treat the localizer scout image (taken by the CT technologist prior to the main scan) like a chest radiograph. We will then use the axial images from the helical CT scan to train the x-ray voxelization algorithm, and compare with the results of existing x-ray voxelization algorithms.
