Software toolbox that can generate a scalable mitral valve geometry using MATLAB. The model can be parameterized using two alternative procedures: (1) based on patient-specific dimensions obtained from patient data (e.g. medical image modalities) and directly inputted by the user or (2) using average dimensions derived from mathematical proportions relating MV anatomical segments based only on the anteroposterior diameter. The toolbox generates two different outputs: a mitral valve geometrical model (.stl file) or an input file for computational simulations with LS-DYNA. Further guidance on how to use the toolbox is provided in the "Instructions - READ ME" document, and in the "documentation" folder, after extracting the .zip folder.
