QStrain RE


MR Feature Tracking

MR Feature Tracking is a powerful image post-processing technique that has been developed to extract strain data from “bread and butter” MRI ssfp cines.

Workflow

Integrated in Medis Suite MR, QStrain offers a seamless and streamlined workflow for advanced quantification of wall deformation. Contours already traced for global function in QMass® can be re-used to carry out feature tracking and quantify strain results, with minimal amount of extra effort.

Results

QStrain RE (Research Edition) provides a wealth of information, presented in a smartly designed user interface, and the comprehensive output comes as a clearly organized xml, that can be directly loaded with MS-Excel. Strain results are available for LV, RV and the Left Atrium as well.
