Segmentation And Statistical Analysis Of Imaged And Simulated 3d Chromosome Territories, Hannah Varney

Electronic Theses and Dissertations

With advances in microscopy in the 21st century, more accurate measurements of the morphology and position of chromosome territories (CTs) during interphase within the cell nucleus can be obtained. These measurements have determined that CTs are non-randomly positioned, and their position and shape can change during diseases like breast cancer, pancreatic cancer, and Huntington’s Disease. The 2.5D Wavelet Transform Modulus Maxima segmentation method uses multi-scale edge detection to accurately segment objects in 3D images to find variables such as surface area, volume, and diameter without assuming a spherical or ellipsoidal shape. Measurements of centroid distance, shell distance and radial distance …
