Advanced TSI for quantitative analysis
Overview
GE continues to invest in the development of clinical tools for the diagnosis and treatment of heart failure. Tissue Synchronization Imaging (TSI) is a parametric imaging tool based on Tissue Velocity Imaging that provides clinicians with additional image enhancement for assessing delayed cardiac wall motion.
The TSI parametric image analyzes the tissue velocity signals within the image to determine the peak velocities of a specified portion of the cardiac cycle. Since these peaks will occur in relation to overall motion, delayed wall motion will produce a delayed peak velocity.
GE takes TSI to the next level with multi-dimensional imaging. Using multi-dimensional imaging, users can acquire three planes simultaneously from the same cardiac cycle. They are able to generate a bull's-eye display along with a 4D model, with quantitative measurements and surface mapping. This allows them to communicate cardiac dyssynchrony to electrophysiologists and referring physicians.
TSI is a quantitative clinical tool that provides insight about the extent of asynchrony. GE continues to build on the clinical value of TSI with additional quantitative enhancements for the advanced user. TSI Trace provides rapid access totime velocity trace, making it easier to quantitatively assess time-to-peak velocity data.
