Modern GUI Design

Create patient-specific models of vasculature using an intuitive and responsive user interface. Start with your image data by importing it to CRIMSON using one of a variety of supported formats or directly from your DICOM storage. Specify the approximate centerlines of the vessels in just a few clicks, use the 2D segmentation toolbox to segment the vessel wall at multiple locations along the centerline and create the first 3D segmentation of one of the vessels using the most fitting lofting algorithm. Create the 3D segmentations for all the vessels of interest in the vessel tree and create a full 3D model through blending the individual vessels together. Create a 3D mesh and specify the simulation parameters and boundary conditions to prepare your patient-specific simulation for running on a supercomputer.

Comprehensive Segmentation toolbox

Depending on the complexity of the vessel wall, use the simple circles or ellipses or more sophisticated semi-automatic segmentation techniques, such as region growing, to segment the vessel wall in 2D slice perpendicular to the centrelines of the vessels. Enjoy the full support of undo/redo operations, live preview of the 3D segmentation results and separate threads for lengthy operations that keep CRIMSON UI intuitive and responsive.

Graphical specification of boundary conditions

Specify the boundary conditions for your simulation in an intuitive manner using CRIMSON's boundary condition builder. Apply the boundary conditions to the faces of your choice by simply selecting them interactively in the 3D display of your model. The face selection will persist even when you modify your vascular tree model by adding or removing vessels.

Patient-specific velocity profiles from MRI/Colour Doppler image data

CRIMSON allows the use of patient-specific inlet and outlet velocity profiles automatically adapted from MRI and ultrasound (colour Doppler) images. CRIMSON allows you to tweak the degree of smoothing over time and space to impose a periodic velocity profiles at the boundary segment of choice, removing the need for the use of idealised profiles such as parabolic, plug and Womersley and use the profile measured directly from the patient.
