Abstract: An improved method and system for identifying and displaying related images obtained during an examination is disclosed. Each image includes both pixel data, corresponding to the image to be displayed, and location information, defining a relationship between the pixel data and a reference point. During a review of the images, a physician may identify an abnormality or particular region of interest in one image. The location information corresponding to the position identified by the physician within the image is obtained from the image file. Having identified location information for a particular location on the first image, the system analyzes the location information corresponding to the pixel data for each of the other stored images to identify any other image that intersects the identified location. All images that intersect the identified location may then be displayed adjacent to the first image for inspection by the physician.

Abstract: Embodiments presented herein provide apparatus and methods for imaging-assisted determination of pressure gradient of blood flow across a valve orifice in a cardiovascular circuit without the use of velocity data measured at the valve orifice. An embodiment of the methods comprise creating an image of a valve orifice, creating a planimeter slice from the image of the valve orifice including a trace of the perimeter of the valve orifice, determining the valve orifice area by determining the area contained within the trace, determining the instantaneous flow rate through the valve orifice based on bulk flow data away from the valve, and determining the instantaneous pressure gradient across the valve orifice from the valve orifice area and the instantaneous flow rate.
