Method and apparatus of lesion detection and validation based on multiple reviews of a CT image
First Claim
1. An object detection apparatus comprising:
- a DAS configured to acquire diagnostic data of a subject;
an image reconstructor configured to reconstruct at least one image of the subject from the diagnostic data;
a data retrieval device configured to retrieve a first set of bookmarks identifying a first set of objects of interest in an image; and
a computer programmed to;
display the image on a console;
detect inputs from a user corresponding to a second set of bookmarks identifying a second set of objects of interest in the image; and
selectively incorporate each bookmark of the first set into the second set of bookmarks.

Abstract
An object detection apparatus includes a data acquisition system configured to acquire diagnostic data of the subject, an image reconstructor configured to reconstruct at least one image of the subject from the diagnostic data, and a data retrieval device configured to retrieve a first set of bookmarks identifying a first set of objects of interest in the at least one image. The object detection apparatus further includes a computer programmed to display the at least one image on a console and detect input from the user corresponding to a second set of bookmarks identifying a second set of objects of interest in the image. The computer is further programmed to selectively allow the user to incorporate each bookmark of the first set of bookmarks into the second set of bookmarks.

display the first set of bookmarks and the second set of bookmarks; and
color differentiate the first set of bookmarks from the second set of bookmarks.

-
8. The object detection apparatus of claim 1 wherein the computer is further programmed to display the first set of bookmarks and the second set of bookmarks and assign a unique shape to one of the sets to visually differentiate between the sets of bookmarks.
-
9. The object detection apparatus of claim 1 wherein the computer is further programmed to automatically determine duplicates between the first set of bookmarks and the second set of bookmarks.
-
10. The object detection apparatus of claim 1 incorporated into a radiation based imaging system.
-
11. The object detection apparatus of claim 9 wherein the radiation based imaging system includes a CT system.
-
12. A computer readable storage medium having a computer program for determining similarities and differences between separate examinations of a diagnostic image stored thereon and includes a set of instructions that when executed by a computer causes the computer to:
-
access imaging data from a DAS;
display an image of a subject from the imaging data for examination;
bookmark a primary set of objects of interest based on a set of inputs from a user;
access from memory bookmarks for a secondary set of objects of interest from a separate examination of the image;
prompt the user to selectively accept each of the secondary set of objects of interest; and
generate a final set of objects of interest from the primary set of objects of interest and the accepted objects of interest from the secondary set of objects of interest. - View Dependent Claims (13, 14, 15, 16, 17, 18)
display a copy of the image to another user; and
bookmark the secondary set of objects of interest based on a set of inputs from the another user.
-
-
15. The computer readable storage medium of claim 12 wherein the set of instructions further causes the computer to display a GUI with the image in a portion of the GUI and a navigation tool in another portion, the navigation tool configured to enable the user to view each of the primary and the secondary sets of objects of interest.
-
16. The computer readable storage medium of claim 15 wherein the set of instructions further causes the computer to visually differentiate the primary set of objects of interest and the secondary set of objects of interest from one another by color.
-
17. The computer readable storage medium of claim 15 wherein the set of instructions further causes the computer to visually differentiate the primary set of objects of interest and the secondary set of objects of interest from one another by shape.
-
18. The computer readable storage medium of claim 12 wherein the set of instructions further causes the computer to display at least one of an oblique, an axial, a coronal, and a sagittal view of the subject.
-
19. A method of determining lesion presence in an image of a subject, the method comprising the steps of:
-
reviewing a diagnostic image of a subject;
identifying a first set of lesions in the diagnostic image;
bookmarking the first set of lesions;
retrieving bookmarks corresponding to a second set of lesions identified in a separate review of the diagnostic image;
navigating through the bookmarks for the second set of lesions;
selectively incorporating bookmarks from the second set of lesions with bookmarks from the first set of lesions; and
generating a final set of bookmarks corresponding to a final set of lesions believed to be present in the diagnostic image. - View Dependent Claims (20, 21, 22, 23, 24, 25)

-
26. A lesion detection tool comprising:
-
means for assigning bookmarks to a first set of lesions in a diagnostic image;
means for retrieving bookmarks for a second set of lesions identified in a separate review of the diagnostic image; and
means for selectively incorporating bookmarks from the second set of lesions into the bookmarks for the first set of lesions.
