Abstract: The present approach provides a non-invasive methodology for estimation of coronary flow and/or fractional flow reserve. In certain implementations, various approaches for personalizing blood flow models of the coronary vasculature are described. The described personalization approaches involve patient-specific measurements and do not assume or rely on the resting coronary flow being proportional to myocardial mass. Consequently, there are fewer limitations in using these approaches to obtain coronary flow and/or fractional flow reserve estimates non-invasively.

Abstract: Methods and systems are provided for reconstructing and automatically segmenting an image. In one embodiment, a method comprises generating a first image from acquired projection data based on an iterative reconstruction algorithm, generating a second image from the acquired projection data based on a modified iterative reconstruction algorithm, segmenting the second image to obtain segments, segmenting the first image based on the segments of the second image, and outputting the segmented first image to a display. In this way, an image which may otherwise prove challenging for an automatic segmentation process may be accurately segmented without sacrificing textural details of the image.
