A framework for the merging of pre-existing and correspondenceless 3D statistical shape models

A bi-ventricular cardiac atlas built from 1000+ high resolution MR images of healthy subjects and an analysis of shape and motion

“…Recently, Hoogendoorn et al proposed a bilinear shape model in which the inter-subject variation and inter-phase variation are encoded separately in two dimensions (Hoogendoorn et al, 2009(Hoogendoorn et al, , 2013. To utilise pre-existing statistical shape models, Pereañez et al proposed a framework of merging multimodality models by spatial normalisation and eigenspace fusion (Pereañez et al, 2014). Cardiac motion can be encoded either implicitly or explicitly.…”

Simultaneous extraction of endocardial and epicardial contours of the left ventricle by distance regularized level sets

“…Segmentation of the left ventricle (LV) plays an important part in noninvasive assessment of ventricular function, which is especially important in diagnosing and treating cardiovascular disease. [1][2][3][4][5][6][7]9,10 Cine MRI has been proven to be an accurate and reproducible modality for quantitative evaluation of left ventricular function. 6,[11][12][13][14][15][16][17][18] Relevant measurements include ventricular volume, mass, and cavity ejection fraction (EF), which provide important characteristics of heart function and can be obtained based on the results of delineating endocardial and epicardial boundaries using segmentation techniques.…”
