Frame rate enhancement of three dimensional echo cartographic sequences of beating hearts
Children's Hospital Boston
posted on 02/11/2010
This invention consists of a method and algorithm for increasing the frame rate for three dimensional ultrasound sequences of periodically moving cardiac structures. Frame rate is especially important in studying intra-cardiac structures where valve closure times are on the order of micro seconds and leafet flutter can be on the order of 100Hz(or higher). Current of-the-shelf solutions to volumetric ultrasound imaging are limited to approximately 30 volumes per second due to the time it takes to send and receive all of the ultrasound pulses necessary to reconstruct a volume. While this frame rate is suffcient for real time human observation of basic ventricular function and to assess valve competency, understanding cardiac dynamics requires greater frame rates. This invention achieves these higher rates by a novel method of post-hoc anlysis using ECG data.
