Abstract
Official abstract text for this publication.
The 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. The method comprises steps of determining a point contained within the walls of the vessel, determining a closed path which approximates the inner circumference of the wall of the vessel, and determining the area of the closed path when the vessel is most expanding in order to get a measurement of the maximum lumen. This method may enable the clinical personnel to quickly evaluate the flow property e.g. of an inserted bypass vessel and, thereby, conclude if the surgical intervention is successful or if adjustments are required.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for determining flow properties of a blood vessel, the system comprising a processing unit for analyzing medical images of cross-sectional views of the blood vessel, where the images are obtained from a medical imaging device, and where the processing unit includes electronic hardware and/or a processor for executing computer program code, the hardware and/or the computer program code being configured for analyzing the images by performing step…
