Medical imaging and computer-aided flow analysis of a heart with atrial septal defect

摘要: Computer-aided magnetic resonance (MR) fluid motion tracking and cardiac vorticity quantification of the right atrial flow is implemented in this study to suggest a new method for diagnosis an septal defect (ASD). MR signals blood moving chamber can be represented as image vary intensity at every consecutive phase. A was devised perform analysis using imaging without modification scan mode or protocol that allows velocity encoding. single vortex multiple vortices may appear chamber. However, fields any scenario are normally unable reveal information concise analysis; therefore, addition maps, maps on which field superimposed presented. Through case study, difference strengths pre- post-atrial occlusion examined, results verified computational dynamics. Based framework, degree vortical assessed atrium subject with defect. relationship established between ASD. As such, there clear utility developed system its potential prognostic investigative tool quantitative assessment abnormalities parallel examining images.
