Abstract

In some embodiments, the present specification describes methods for displaying a three-dimensional image of an isolated threat object or region of interest with a single touch or click and providing spatial and contextual information relative to the object, while also executing a view dependent virtual cut-away or rendering occluding portions of the reconstructed image data as transparent. In some embodiments, the method includes allowing operators to associate audio comments with a scan image of an object. In some embodiments, the method also includes highlighting a plurality of voxels, which are indicative of at least one potential threat item, in a mask having a plurality of variable color intensities, where the intensities may be varied based on the potential threat items.

First claim

We claim:

1. A method of enabling at least a first operator and a second operator to annotate a scan image of an object, the method comprising:
presenting a first graphical interface to the first operator, wherein the first graphical interface comprises a first icon;
upon receiving an indication that the first icon has been activated on the first graphical interface, initiating a first audio recording and changing the first icon into a second icon;
upon receiving an indication that the second icon has been activated, terminating the first audio recording and generating a first audio file of the first audio recording;
displaying a third icon on the first graphical interface, wherein the third icon is indicative of the first audio file;
presenting a second graphical interface to the second operator, wherein the second graphical interface comprises the first icon and the third icon;
upon receiving an indication that the third icon has been activated, playing the first audio recording;
upon receiving an indication that the first icon has been activated on the second graphical interface, initiating a second audio recording and changing the first icon into the second icon;
upon receiving an indication that the second icon has been activated, terminating the second audio recording and generating a second audio file of the second audio recording; and
displaying a fourth icon on the second graphical interface, wherein the fourth icon is indicative of the second audio file.

2. The method of claim 1 , wherein the first audio file is associated with an identification of the first operator.

3. The method of claim 2 , wherein the second audio file is associated with an identification of the second operator.

4. The method of claim 2 , wherein the second graphical interface is further configured to display the identification of the first operator.

5. The method of claim 1 , wherein the first audio file is associated with a first date and a first time of the first audio recording.

6. The method of claim 5 , wherein the second audio file is associated with a second date and a second time of the second audio recording.

7. The method of claim 1 , further comprising permitting the first operator to visually maneuver the scan image in the first graphical interface during the first audio recording.

8. The method of claim 1 , wherein the first graphical interface comprises an input configured to receive first textual comments from the first operator.

9. The method of claim 8 , wherein the second graphical interface is further configured to display the first textual comments from the first operator.

10. The method of claim 9 , wherein the second graphical interface comprises an input configured to receive second textual comments from the second operator.

11. The method of claim 10 , wherein the second graphical interface is configured to display the second textual comments sequential to the first textual comments.

12. The method of claim 1 , wherein the first graphical interface comprises a first audio progress bar configured to represent a remaining amount of storage available for the first audio recording.

13. The method of claim 12 , wherein the second graphical interface comprises a second audio progress bar configured to represent a remaining amount of storage available for the second audio recording.

14. The method of claim 1 , wherein the first icon is indicative of a record button and wherein the second icon is indicative of a stop record button.

15. A method of enabling at least a first operator and a second operator to annotate a scan image of an object, the method comprising:
presenting a first graphical interface to the first operator, wherein the first graphical interface comprises a first icon;
upon receiving an indication that the first icon has been activated, initiating a first audio recording and changing the first icon into a second icon;
enabling the first operator to visually maneuver the scan image in the first graphical interface during the first audio recording;
upon receiving an indication that the second icon has been activated, terminating the first audio recording and generating a first audio file of the first audio recording;
displaying a third icon on the first graphical interface, wherein the third icon is indicative of the first audio file;
permitting the first audio file to be deleted, provided the object has not been cleared and not permitting the first audio file to be deleted if the object has been cleared;
presenting a second graphical interface to the second operator, wherein the second graphical interface comprises the first icon and the third icon;
upon receiving an indication that the third icon has been activated, playing the first audio recording;
upon receiving an indication that the first icon has been activated, initiating a second audio recording and changing the first icon into the second icon;
enabling the second operator to visually maneuver the scan image in the second graphical interface during the second audio recording;
upon receiving an indication that the second icon has been activated, terminating the second audio recording and generating a second audio file of the second audio recording; and
displaying a fourth icon on the second graphical interface, wherein the fourth icon is indicative of the second audio file.

16. The method of claim 15 , wherein the first audio file is associated with an identification of the first operator and the second audio file is associated with an identification of the second operator.

17. The method of claim 15 , wherein the first graphical interface comprises an input configured to receive first textual comments from the first operator and wherein the second graphical interface is further configured to display the first textual comments from the first operator.

18. The method of claim 17 , wherein the second graphical interface comprises an input configured to receive second textual comments from the second operator and wherein the second graphical interface is configured to display the second textual comments sequential to the first textual comments.

19. The method of claim 15 , wherein at least one of the first graphical interface and the second graphical interface comprises an audio progress bar configured to represent a remaining amount of storage available for the first audio recording or the second audio recording.

20. The method of claim 15 , wherein the first icon is indicative of a record button and wherein the second icon is indicative of a stop record button.
