Displaying and navigating computer-aided detection results on a review workstation

摘要

Display and navigation for multiple computer-aided detection (CAD) detections is described. A medical image is displayed to a viewer, and a request is received to instantiate CAD-assisted viewing. A timewise presentation sequence for the CAD detections is automatically computed according to a predetermined sequencing criterion. For each CAD detection, an expanded presentation window is displayed for its associated location in the medical image, the expanded presentation windows being displayed according to the timewise presentation sequence. Also described is a navigational tool comprising a plot of an operating curve onto which a computed feature associated with the CAD algorithm can be mapped, the operating curve characterizing an application of the CAD algorithm to a reference database of mammographic cases having known diagnoses. The navigational tool further comprises a plurality of CAD pointer icons spatially distributed therealong according to mappings of the computed feature for the CAD detections onto the operating curve.

主权项

1. A computer-implemented method for displaying a plurality of computer-aided detection (CAD) detections associated with a tomosynthesis case, the tomosynthesis case comprising a plurality of images, the tomosynthesis case being processed by a CAD algorithm that identifies CAD detections therein based at least in part upon respective computed features associated with respective CAD detections: displaying the plurality of tomosynthesis images to a viewer, respective tomosynthesis images comprising respective CAD markers corresponding to respective locations of respective CAD detections in respective tomosynthesis images; mapping a computed feature onto an operating curve of a navigational tool, the navigational tool comprising a plot of the operating curve and a plurality of CAD pointer icons, respective CAD pointer icons corresponding to respective CAD detections, the plurality of CAD pointer icons being spatially distributed along the navigational tool according to the mapping, each CAD pointer icon representing a CAD detection and visually communicating an aspect of the CAD detection to the viewer by the position of the graphical symbol on the plot; and displaying the navigational tool in proximity to at least one tomosynthesis image to the viewer.
