Abstract

A computerized system and method for viewing a set of voxel data on a display device attached to a computer is disclosed. In one embodiment of the invention, the computerized system has a number of different components. A retrieve data set component retrieves the set of voxel data, the set of voxel data having already been acquired in accordance with acquisition parameters of a protocol. A protocol selector component selects the protocol in accordance with the set of voxel data retrieved, the protocol including preset adjustments for the volume-rendering of the data. An image gallery component displays one or more images of the set of voxel data in accordance with the preset adjustments of the protocol. An examination viewer component permits the changing of the preset adjustments of the protocol as to a particular image selected. within the image gallery component. A report generator and viewer component generates a report based on snap shots of images taken within the examination viewer component. A print and post component prints the generated report to a printer operatively coupled to the computer, and/or posts the report as an HTML file to a web browser for retrieval over the Internet or an intranet.

Claims

1. A computerized system for displaying a set of voxel data on a display device of a computer, the computerized system comprising:

a retrieve data component operative to retrieve the set of voxel data from a storage device operatively coupled to the computer;

a protocol selector component operative to automatically select an appropriate protocol from a set of predefined protocols, said protocol being determined by at least one field in the set of voxel data, each of said predefined protocols defining a set of viewing characteristics to be applied to the set of voxel data;

an image gallery component operative to display a gallery of volume-rendered images of the set of voxel data and providing an interface allowing the selection of one of the volume rendered images, each of said volume-rendered images displayed on the display device in accordance with the selected appropriate protocol; and

an examination viewer component operative to modify the volume-rendered image selected from the gallery by adjustment of one or more visual controls governing the display of the image on the display device.

2. The computerized system of claim 1, wherein the set of viewing characteristics includes one or more attributes selected from the group consisting of:

contrast, transparency, and color.

3. The computerized system of claim 1, wherein the volume-rendered images displayed in the gallery are automatically determined based on the selected appropriate protocol.

4. The computerized system of claim 1, wherein the one or more visual controls are automatically determined by the selected appropriate protocol.

5. The computerized system of claim 1, wherein the one or more visual controls are preset to a value determined by the selected appropriate protocol.

6. The computerized system of claim 1, wherein the examination viewer component further provides for the selection by a user of an alternative protocol to control the display of the volume-rendered images.

7. The computerized system of claim 1, further comprising a report component operative to generate a report based on one or more snap shots taken within the examination viewer component.

8. The computerized system of claim 1, further comprising a print and post component, to generate a copy of the report generated by the report generator.

9. A method for displaying a set of voxel data on a display device of a computer, the method comprising:

retrieving the set of voxel data;

selecting an appropriate protocol from a set of predefined protocols, said protocol being determined by at least one field in the set of voxel data, each of said predefined protocols defining a set of viewing characteristics to be applied to the set of voxel data;

displaying a gallery of volume-rendered images of the set of voxel data, each of said volume-rendered images displayed on the display device in accordance with the selected appropriate protocol; and

displaying one or more visual controls operative to modify a volume-rendered image selected from the gallery.

10. The method of claim 9, wherein the set of viewing characteristics includes one or more attributes selected from the group consisting of:

contrast, transparency, and color.

11. The method of claim 9, wherein the volume-rendered images displayed in the gallery are automatically determined based on the selected appropriate protocol.

12. The method of claim 9, wherein the one or more visual controls are automatically determined by the selected appropriate protocol.

13. The method of claim 9, wherein the one or more visual controls are preset to a value determined by the selected appropriate protocol.

14. The method of claim 9, further comprising generating a report based on the volume-rendered image selected from the gallery.

15. A computer readable medium having computer executable instructions for performing a method for displaying a set of voxel data on a display device of a computer, the method comprising:

retrieving the set of voxel data;

selecting an appropriate protocol from a set of predefined protocols, said protocol being determined by at least one field in the set of voxel data, each of said predefined protocols defining a set of viewing characteristics to be applied to the set of voxel data;

displaying a gallery of volume-rendered images of the set of voxel data, each of said volume-rendered images displayed on the display device in accordance with the selected appropriate protocol; and

displaying one or more visual controls operative to modify a volume-rendered image selected from the gallery.

16. The computer readable medium of claim 15, wherein the set of viewing characteristics includes one or more attributes selected from the group consisting of:

contrast, transparency, and color.

17. The computer readable medium of claim 15, wherein the volume-rendered images displayed in the gallery are automatically determined based on the selected appropriate protocol.

18. The computer readable medium of claim 15, wherein the one or more visual controls are automatically determined by the selected appropriate protocol.

19. The computer readable medium of claim 15, wherein the one or more visual controls are preset to a value determined by the selected appropriate protocol.

20. The computer readable medium of claim 15, further having computer executable instructions for generating a report based on the volume-rendered image selected from the gallery.
