Title: The Innovative Contributions of Saara Marjatta Sofia Totterman
Introduction
Saara Marjatta Sofia Totterman is a prominent inventor based in Rochester, NY (US). She has made significant contributions to the field of medical imaging, holding a total of 8 patents. Her work focuses on improving the quality and accuracy of diagnostic imaging techniques, particularly in computed tomography (CT) and magnetic resonance imaging (MRI).
Latest Patents
One of her latest patents is a system and method for reducing or eliminating streak artifacts and illumination inhomogeneity in CT imaging. This innovative algorithm addresses the challenges posed by metal implants and varying tissue densities in CT images. It consists of two main steps: illumination correction and adaptive 3D filtering. The algorithm begins by estimating the direction of streaks and the degree of inhomogeneous densities using gray scale morphology dilatation. It then estimates the correct densities and reduces streaks through adaptive 3D filtering, which is tailored to the streak direction and local image contrast.
Another notable patent involves a method and system that forms an isotropic, high-resolution, three-dimensional diagnostic image from two-dimensional image data scans. This technique enhances the resolution of MRI scans, which typically have higher resolution within a slice than between slices. By taking two MRI scans in different, preferably orthogonal, directions and maximizing the correlation between their gradients, a high-resolution image is created. This method can also utilize multiple receiving coils and optimize the number of spectral bands based on image contrast.
Career Highlights
Saara has worked with several esteemed organizations, including Virtualscopics LLC and the University of Rochester. Her experience in these institutions has allowed her to develop and refine her innovative imaging techniques, contributing to advancements in medical diagnostics.
