Title: Lasse Riis Østergaard: Innovator in Medical Imaging and Blood Flow Analysis

Introduction

Lasse Riis Østergaard is a notable inventor based in Klarup, Denmark. He has made significant contributions to the fields of medical imaging and blood flow analysis, holding 2 patents that showcase his innovative approach to solving complex medical challenges.

Latest Patents

One of his latest patents is a "System for determining flow properties of a blood vessel." This invention relates to a method for providing quantitative measures of the flow property of a blood vessel. The method is based on analyzing cross-sectional images of a vessel by estimating the area of the lumen of the vessel. It involves determining a point within the walls of the vessel, creating a closed path that approximates the inner circumference of the vessel's wall, and measuring the area of this path when the vessel is most expanded. This method enables clinical personnel to quickly evaluate the flow properties of an inserted bypass vessel, helping to determine the success of surgical interventions.

Another significant patent is for "Computerised cortex boundary extraction from MR images." This method processes digital images, such as magnetic resonance images of the brain. It involves providing a digital dataset that represents a deformable curve or surface approximating the boundary between different brain structures. A vector force field is applied to iteratively deform this curve or surface towards the boundary between the cerebral cortex and cerebrospinal fluid, facilitating the reconstruction of the cortex's folded structure.
