Computed Tomography Images Enhancement and Denoising

In Computed Tomography (CT), X-ray radiation is used to penetrate through the internal structure of the patient body in order to produce digital images. Therefore patient could be exposed to certain level of X-ray radiation dose. Accumulation of these exposures beyond certain threshold could increase risk of fatal cancer. Thus it is of paramount importance to lower the amount of radiation exposure during CT images acquisition. However, a low radiation dose in CT images would result to lower image quality. To maintain lower dose usage and still produce images with a high quality therefore one needs to develop advanced image processing tools in order to reduce noise and enhance CT images. This internship therefore will attempt to bring advanced methods of image processing tools that are specifically tailored to reduce noise and enhance CT images to the partner organization.
