The blood flow patterns inside your heart are likely to contain information about your cardiac health. An automated pipeline for estimating these intra-cardiac blood flow patterns might one day be a vital tool, helping doctors make informed decisions in diagnosis and treatment of cardiac diseases. The pipeline is meant to work “at the push of a button” to provide novel metrics based on existing data. This project aims to prove that such a “button” can be made.
In this work a pipeline has been constructed based on temporal volumetric image registration of cardiac imaging from computed tomography or magnetic resonance which are already being used in clinic today. The pipeline is applied on a dynamic heart phantom based on a cardiac computed tomography scan. The pipeline is validated by measuring the phantom blood flow patterns using ultrasound vector flow imaging with a controlled setup aimed at repeatability and spatial precision in measurements.
The results demonstrate that with proper validation such tools may be made available to clinicians in the future and will operate "at the push of a button".
