Abstract
A navigation tool that provides a side-by-side display of two temporally related medical images of the same region of a patient. A plurality of lines extend between the images, at least a first line beginning at a feature at a first location in a first image and ending at a corresponding feature at a corresponding location in the second image and at least a second line extending from a feature found at a second location in one of the images toward a corresponding second location in the other image and indicating a feature found in one image but not the other. Preferably, the navigational tool also includes a scroll bar alongside the display of medical images. On the scroll bar are a series of markers, each marker corresponding to one of the plurality of lines that extend between the images and preferably being aligned with that line.

22. A method of comparing first and second temporally related medical images comprising:
-
retrieving first and second medical images from a memory component, the first and second medical images being images of the same thing at different times; locating corresponding features in each of the first and second medical images, displaying on a display device the first medical image and the second medical image along-side the first medical image, identifying on the first medical image and the second medical image the corresponding features, locating at least one feature found in one of the first or second medical images but not in the other, identifying on a displayed medical image the at least one feature found in one of the first and second medical images but not the other; and displaying on the display device a first line extending between a first feature at a first location in the first medical image and a corresponding feature at a corresponding first location in the second medical image and a second line extending from a second feature at a second location in one of the medical images toward a corresponding second location in the other image where no corresponding feature is found.
