Clinical data about heart failure make it clear that there is a need to develop a limited echocardiogram assisted by automated functions as a screening tool to identify people who have asymptomatic left ventricular dysfunction and who can potentially benefit from proven therapies to prevent the development of symptomatic HF. Our preliminary tests show that an abbreviated version of an echo consisting of only 6 views can provide enough information for the binary screening. Six expert echo readers achieved near-perfect performance in identifying normal vs. abnormal echoes using 6 views, as compared to the diagnosis based on the full echocardiogram. The ground truth about the geometry of the heart was provided by one expert echo reader in the form of drawings and measurements. The drawings were used as a prior in a computational model that extracts the contour of the left ventricle as the shortest path in a log-polar (complex log) representation of the ventricle. This model may represent the first step in the development of an automated function for screening echocardiogram.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
