Presentation of computer-aided detection/diagnosis (CAD) results
A user may be provided with identified regions of interest superimposed on a larger image, which may permit the user to individually examine the regions of interest. The regions of interest may be independently windowed and/or leveled and/or magnified according to parameters associated with the region of interest, which parameters may be generated by a computer-aided detection algorithm.
1 . A method of displaying one or more regions of interest within a radiological image, comprising:
displaying the radiological image; and
superimposing on the radiological image one or more of the regions of interest, wherein the one or more regions of interest are superimposed in one or more locations in the radiological image to which they correspond, and wherein the one or more regions of interest are displayed as magnified sub-images with respect to the radiological image.
2 . The method according to claim 1 , wherein each region of interest is independently windowed and leveled according to parameters determined for the particular region of interest.
3 . The method according to claim 1 , wherein each region of interest is independently magnified according to one or more parameters determined for the particular region of interest.
4 . The method according to claim 1 , further comprising:
enabling a user to select, for one or more regions of interest, at least one display option selected from the group consisting of a magnification, a windowing level, and a leveling level.
5 . The method according to claim 1 , further comprising:
enabling a user to select among multiple images registered for a given region of interest.
6 . The method according to claim 5 , wherein said multiple images are selected from the group consisting of: an image having windowing, leveling, and magnification according to one or more parameters determined for the given region of interest; a soft-tissue image; a bone image; and a color-inverted image.
7 . The method according to claim 1 , further comprising:
enabling a user to move a displayed region of interest to another location.
8 . The method according to claim 7 , wherein said enabling includes providing a graphical indication of the location to which a moved region of interest corresponds.
9 . The method according to claim 1 , further comprising:
enabling a user to select a number of regions of interest to be displayed.
10 . The method according to claim 1 , further comprising:
downloading software to implement said displaying and said superimposing.
11 . The method according to claim 1 , further comprising:
automatically cycling through a sequence of images registered for at least one region of interest.
12 . A processor-readable medium containing instructions that, when executed by a processor, cause the processor to implement a method of displaying one or more regions of interest within a radiological image, the method comprising:
displaying the radiological image; and
superimposing on the radiological image one or more of the regions of interest, wherein the one or more regions of interest are superimposed in one or more locations in the radiological image to which they correspond, and wherein the one or more regions of interest are displayed as magnified sub-images with respect to the radiological image.
13 . The medium according to claim 12 , wherein each region of interest is independently windowed and leveled according to parameters determined for the particular region of interest.
14 . The medium according to claim 12 , wherein each region of interest is independently magnified according to one or more parameters determined for the particular region of interest.
15 . The medium according to claim 12 , wherein the method further comprises:
enabling a user to select, for one or more regions of interest, at least one display option selected from the group consisting of a magnification, a windowing level, and a leveling level.
16 . The medium according to claim 12 , wherein the method further comprises:
enabling a user to select among multiple images registered for a given region of interest.
17 . The medium according to claim 16 , wherein said multiple images are selected from the group consisting of: an image having windowing, leveling, and magnification according to one or more parameters determined for the given region of interest; a soft-tissue image; a bone image; and a color-inverted image.
18 . The medium according to claim 12 , wherein the method further comprises:
enabling a user to move a displayed region of interest to another location.
19 . The medium according to claim 18 , wherein said enabling includes providing a graphical indication of the location to which a moved region of interest corresponds.
20 . The medium according to claim 12 , wherein the method further comprises:
enabling a user to select a number of regions of interest to be displayed.
21 . The medium according to claim 12 , wherein the method further comprises:
automatically cycling through a sequence of images registered for at least one region of interest.
22 . A system comprising:
a computer-aided detection (CAD) processing module to process at least one radiological image and to identify one or more regions of interest; and
a display processing module to display a radiological image and to superimpose on the radiological image one or more of the regions of interest, wherein the one or more regions of interest are to be superimposed in one or more locations in the radiological image to which they correspond, and wherein the one or more regions of interest are to be displayed as magnified sub-images with respect to the radiological image.
23 . The system according to claim 22 , further comprising:
a user interface to permit a user to select among various options for one or more of the regions of interest by means of scrolling, clicking, or other non-keyboard techniques.
24 . The system according to claim 23 , wherein said user interface includes a graphical user interface selection scheme.
25 . The system according to claim 23 , wherein said various options include one or more options selected from the group consisting of: magnification; windowing; leveling; a corresponding registered image; a color-inverted image; brightness; and contrast.
