Rat uterus meshes

<h2><b>Rat uterus meshes</b></h2><h3><b>General information</b></h3><p dir="ltr">This item contains surface and volumetric meshes of the rat uterus (<b>AWA015_PTA_1_*</b>)<i> </i>and the ovarian segment <i>(</i><b>AWA015_PTA_2_Ova_</b><b>*</b>) along with the fibres identified with structure tensors. They were generated from the muscle segmentation of uCT images. The rat was in the oestrus phase of its cycle.</p><p dir="ltr">This item also contains a .bin file containing the high-resolution ovarian segment surface mesh registered to the organ mesh and a figure showing the two meshes and the distances between them after registration.</p><h3><b>Contents</b></h3><p dir="ltr">In the meshes archives:</p><ul><li>The <b>AWA015_PTA_1_Rec_Trans_surface_mesh.stl </b>and <b>AWA015_PTA_1_Rec_Trans_surface_mesh.vtk</b> meshes are exported directly from ITK-SNAP (www.itksnap.org).</li><li>The <b>AWA015_PTA_1_Rec_Trans_surface_mesh.stl</b> mesh was edited in Meshmixer 3.5.474 (Autodesk, Inc.) to correct issues in the surface mesh to generate a volumetric mesh.
