Abstract

A method (12) of estimating one or more physiological parameters, in particular of a cardiac region, based on medical imaging data. An input time series of three-dimensional medical images is received(14), representative of a cardiac region of a patient. A meshless simulation framework is applied (16) for simulating blood flow through at least a portion of the anatomical area captured by the images. The simulation framework comprises in particular simulating force interactions between individual elements of a simulated fluid (representing blood) and individual patches of a tissue structure ofthe imaged cardiac region. One or more physiological parameters (18) are derived based on the simulated blood flow.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of US Provisional Application US 62 / 643218, filed March 15, 2018, and US Provisional Application US 62 / 746633, filed October 17, 2018, which are incorporated herein by reference . technical field [0003] The present invention estimates physiological parameters based on medical image data, in particular based on the application of a simulation framework to medical image data. Background technique [0004] In the field of medical diagnostics, and in particular cardiac diagnostics, there is a growing need for automatic quantification of (eg hemodynamic) parameters from medical images. Biophysical models and simulation techniques or frameworks can provide useful tools to assist in this. Not only can modeling and simulation help to automate and streamline parameter measurements, in many cases parameters that are not directly measurable from medical images can be derived ba...
