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.
1. A computer-implemented method of displaying a computed tomography (CT) scan image, comprising:
a) receiving a user input to modify one or more parameters associated with a filter, to provide one or more user-modified parameters;
b) modifying the filter based on the one or more user-modified parameters, to provide a modified filter;
c) processing the scan image using the modified filter to generate an enhanced scan image in which features indicative of an abnormality are enhanced and at least one feature of the scan image is obscured; and
d) displaying a view of the scan image and a corresponding view of the enhanced scan image so as to enable a visual comparison between the scan image and the enhanced scan image.
2. The method of claim 1 , wherein the view of the scan image and the corresponding view of the enhanced scan image are displayed simultaneously.
3. The method of claim 1 , wherein the view of the scan image and the corresponding view of the enhanced scan image are displayed alternately.
4. The method of claim 3 , wherein the display alternates between the view of the scan image and the view of the enhanced scan image in response to a user input.
5. The method of claim 3 , wherein the scan image and the corresponding view of the enhanced scan image are displayed alternately in a substantially similar position.
6. The method of claim 1 , including receiving a user input for modifying the view, and modifying the displayed view of the scan image and the view of the enhanced scan image correspondingly in response to the user input.
7. The method of claim 6 , wherein the user input is for selecting a slice of the scan image, and the selected slice of both the scan image and the enhanced image are displayed in response to the user input.
8. The method of claim 1 , further comprising receiving a user input for selecting a selectable filter of a plurality of selectable filters, wherein modifying the filter includes modifying the selected selectable filter and processing the scan image includes processing the scan image using the selectable filter.
