Machine Learning Approaches for Myocardial Motion and Deformation Analysis

Nicolas Duchateau, Andrew P. King, Mathieu De Craene
2020 Frontiers in Cardiovascular Medicine  
Information about myocardial motion and deformation is key to differentiate normal and abnormal conditions.  ...  With the advent of approaches relying on data rather than pre-conceived models, machine learning could either improve the robustness of motion quantification or reveal patterns of motion and deformation  ...  Tags and speckles can directly be tracked within the myocardium in tagged MR and 2D/3D echography (within the limits of tag fading, speckles temporal consistency, and out-of-plane motion), contrary to  ...

2006 Medical Physics (Lancaster)  
True alignment of planning and on-board image data was achieved according to a 3D point-based registration of the 6 reference BBs in the CT and CBCT images.  ...  This study examines the accuracy of 3D-3D registration of reference and on-board DTS images to assess the potential of DTS for image-guided radiation therapy (IGRT).  ...  Two independent observers made the MR and US measurements. There was very good correlation between the MR and 3D US volume measurements with Pearson's correlation coefficient of 0.987 (p<0.05).  ...

Real-time tumor motion tracking by 2D/3D registration using on-board kilo-voltage (kV) imaging can lead to a reduction of the PTV.  ...  Therefore MI-based MR-CT registration may vary from scan to scan as MI depends on the joint histogram of the images.  ...  This is a manual process and can be time consuming in cases where several sections using different stains are required.  ...
