Automatic evaluation of left ventricular function from echocardiographic images with LvTrack (BGN)
LV Track is a decision support system for routine quantitative evaluation of LV function. Our proprietary algorithm enables fast and accurate analysis of echocardiographic cine loops for automatic extraction of LV parameters.• A basic prototype of the system (MATLAB) has been developed.
• The system was evaluated in 28 patients, and the algorithm results were compared to expert EF evaluations (correlation = 0.9).
• A clinical database of 300 patients is currently being evaluated.
• Fully automatic LV end-diastolic volume calculation results from 125 patients were compared with expert ED evaluations (correlation = 0.85).
• New software, including advanced software tools, is being developed as a basis for examination of a beta system.
• Automatic selection of LV region of interest (ROI)
• Dynamic LV volume tracking
• Automatic frame selection for evaluation of global LV function and calculation of EF
• Direct evaluation of LV wall mass and segmental wall thickness
• Automatic segmental wall motion analysis during diastole and systole from multiple apical views
• 3D reconstruction
• 3,572 echocardiographic systems are sold annually worldwide, with a total sales of US$430 million.
• 11.5 million echo examinations were performed in 2004 in the USA alone (the cost of an echo examination amounts to US$175-200).
