User interface for computed tomography (CT) scan analysis
An enhanced image is based on an original image. For instance, the original image can be processed using a filter to provide the enhanced image. The original and enhanced images can be displayed side by side or alternately to facilitate a comparison of the original and enhanced images. A user can change one or more enhancement parameters associated with the enhanced image. For example, the user can change the one or more enhancement parameters while viewing the original and enhanced images to determine an effect the change has on the enhanced image. The user can compare the effect of the changed enhancement parameters with his or her own analysis of the original image. The changed enhancement parameters may be applied to other parts of the original image so as to provide a more accurate analysis of those parts.
