Optimising adjacent membrane segmentation and parameterisation in multicellular aggregates by piecewise active contours
In fluorescence microscopy imaging, the segmentation of adjacent cell membranes within cell aggregates, multicellular samples, tissue, organs, or whole organisms remains a challenging task. The lipid bilayer is a very thin ...
Eels: Electric Snakes
(Revista Computación y Sistemas; Vol. 2 No. 2 y No. 3, 1998-12-15)
Abstract. This paper presents the incorporation ofa new internal force for active contours. This internal force is generated by an electric charge, distributed al/-over the active contour. Our extended contour model can ...
Morphing active contours : a geometric approach to topology-independent image segmentation and tracking
A method for deforming curves in a given image to a desired position in a second image is introduced in this paper. The algorithm is based on deforming the first image toward the second one via a partial differential ...
Automated left atrial time-resolved segmentation in MRI long-axis cine images using active contours
(Universidad de Ingeniería y TecnologíaBioMed CentralPE, 2021-06-19)
Background: Segmentation of the left atrium (LA) is required to evaluate atrial size and function, which are important imaging biomarkers for a wide range of cardiovascular conditions, such as atrial fbrillation, stroke, ...
Automatic Identification and Extraction of Pectoral Muscle in Digital Mammography
Mammography is a worldwide image modality used to diagnose breast cancer and can be used to measure breast density (BD). In clinical routine, radiologist perform image evaluations through BIRADS assessment. However, this ...
Modelling SPECT auto-contouring acquisitions for 177Lu & 131I molecular radiotherapy using new developments in Geant4/GATE
Purpose Monte Carlo modelling of SPECT imaging in Molecular Radiotherapy can improve activity quantification. Until now, SPECT modelling with GATE only considered circular orbit (CO) acquisitions. This cannot reproduce ...
