Embodiment Construction

[0066] In general, the present disclosure describes methods and systems for image processing to understand, diagnose, and improve existing and developing new treatments for disease. More specifically, the present disclosure describes methods and systems for qualitative and quantitative analysis of myocardial wall dynamics medical image datasets (eg, 2D cine datasets) derived within the cardiac cycle, such as CT and MRI datasets.

[0067] The methods and systems of the present disclosure can be used in many diagnostic and therapeutic fields. For example, the methods and systems of the present disclosure can aid in the early detection of myocardial insufficiency in subclinical states (or preclinical states when a patient has not been diagnosed with a particular disease or condition) as well as in both acute and chronic ischemia. Patients are usually not treated because all functional parameters appear to be normal, such as a normal ejection fraction (ie, the fraction of blood vo...

Abstract

A method to determine myocardial wall dynamics and tissue characteristics using a method provided to determine myocardial wall dynamics and tissue characteristics using a 3D model of the myocardium. The method comprises generating an epicardial surface and an endocardial surface from a plurality of SAX and LAX slices; identifying a plurality of nodes on the epicardial and endocardial surfaces or in between these surfaces within the myocardium in a reference frame; defining a set of coefficients, each coefficient being associated with the respective location of the corresponding node in a phase; determining the coefficients and in this way determining the model; determining the myocardial wall dynamics in terms of strain values and displacements.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Patent Application No. 61 / 989,214, filed May 6, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure generally relates to image processing for understanding, diagnosis and improving new treatments for existing and developing diseases. More specifically, the present disclosure relates to qualitative and quantitative analysis of myocardial wall dynamics from medical image datasets derived within the cardiac cycle, such as computed tomography (CT) and magnetic resonance imaging (MRI) datasets. Background technique [0004] Imaging is used as a diagnostic tool as well as an experimental tool to study the anatomy and physiology of humans and other animals. It is also used to guide targeted therapy for some diseases such as cancer. Various medical imaging techniques include X-rays, ultrasound, posit...
