A potential new noninvasive computed tomography (CT) and software methodology from Qi Imaging was presented at a poster session during the annual American College of Cardiology (ACC) scientific session. Presented by Massachusetts General Hospital (MGH) researchers, the study, entitled “A New Method Using Cardiac CT Kinematics to Reflect the Activation Pattern Visualized with Electro-anatomical Map: Cardiac CT Phase Time Velocity Activation-Encoded Map,” shows promising results in an effort to simulate an electroanatomical map (EAM), which is an invasive electrophysiology (EP) procedure. MGH researchers coupled ECG-gated, multi-phase CT imaging with PhyZiodynamics software technology from Qi Imaging.
“Our goal was to emulate EP mapping, but use noninvasive CT imaging and novel CT velocity-based software to determine if we could reflect similar myocardial activation patterns,” said Quynh A. Truong, MD, MPH, lead author of the study who is an MGH cardiologist and assistant professor of medicine at Harvard Medical School. “The initial results indicate significant promise for detecting the site of latest activation, a goal that may be important for LV lead placement.”
Based on its imaging algorithms, Qi Imaging’s platform delivers deformable, voxel-to-voxel registration, enabling visual acuity and functional analysis of multimodality imaging parameters. PhyZiodynamics, an advanced 4D processing system, allows the automated registration of DICOM-based modality images into true fidelity 3D and 4D organ data sets which can be interactively interrogated throughout the entire structure while either still or in motion. It enables highly accurate motion coherence and reproducible functional analytics providing the gateway to next generation imaging analytics.
