A Method for Simulating Fluid Flow through Heterogeneous Porous Media
Computational fluid dynamics (CFD) modeling of fluid flow through porous media is resource intensive and available macro (and micro) scale models are based on simplifications which significantly impact the accuracy of simulation results. Moreover, current approaches are mostly based on homogeneity assumption and heterogeneity of the medium is often...

First-Person Perspective, Patient-Registered Medical Image Visualization
In standard medical practice, the patient and their medical image data are decoupled after imaging. Image visualization is primarily confined to screens that are not registered with respect to the patient's body. This is cumbersome and requires more time for healthcare providers to orient the images relevant to the patient. It would be ideal to have...

Customized Endovascular Devices
It is estimated that about one in fifty people have an unruptured brain aneurysm in the United States alone. Endovascular coiling is one of the most common minimally invasive treatment for cerebral aneurysms. However, aneurysm geometry is highly patient-specific, and commercial coils come in pre-defined shapes. This can result in incomplete packing...

Automated Tumor Segmentation
Counting the number of dots on an image has multiple applications. One such application is measuring the number of glomeruli (which appear as dots on images) in an intact kidney using non-destructive techniques to study renal and systemic failures. Some currently available techniques to count the glomeruli and measure their size require the destruction...

An algorithm to estimate glomerular number from kidney magnetic resonance images
Counting the number of dots on an image has multiple applications. One such application is measuring the number of glomeruli (which appear as dots on images) in an intact kidney using non-destructive techniques to study renal and systemic failures. Some currently available techniques to count the glomeruli and measure their size require the destruction...

A One Dimensional Approach to Control Grid Interpolation
Image upscaling through pixel interpolation is used in many different fields to create high resolution images from low resolution images that are not riddled with jagged edges or excessive blurriness. Image resolution limits the extent to which zooming enhances clarity, restricts the quality of digital photograph enlargements, and, in the context...
