Delineation of lung tumor regions from magnetic resonance imaging (MRI) poses many difficulties due to MR signal similarities of the region of interest and surrounding area as well as the influence of respiration. However, accurate segmentation of the tumor region is of utmost importance in planning a radiation therapy since a small error can result in some healthy tissues to receive excessive radiation...
This paper explores the possibility of guiding a biopsy needle inside a breast in real time using ultra-wideband (UWB) circular synthetic aperture radar (CSAR). Collecting a biopsy of a tumor growth inside a breast at the right location is essential for accurate diagnosis. In order to do so, real time navigation and imaging of the tumor location and the biopsy needle is critical. Using very short...
One can find in the literature numerous techniques to reduce noise in Magnetic Resonance Images (MRI). This paper critically reviews modern de-noising algorithms (Gaussian filter, anisotropic diffusion, wavelet, and non-local mean) in terms of their efficiency, statistical assumptions, and their ability to improve brain tumor segmentation results. We will show that although different techniques do...
