Abstract

A system and method for planning surgical procedure including a treatment zone setting view presenting at least one slice of a 3D reconstruction generated from CT image data including a target. The treatment zone setting view presenting a treatment zone marker defining a location and a size of a treatment zone and configured to adjust the treatment zone marker in response to a received user input. The system and method further including a volumetric view presenting a 3D volume derived from the 3D reconstruction and a 3D representation of the treatment zone marker relative to structures depicted in the 3D volume.

Claims

1. A system for planning a treatment procedure, the system comprising:

a computing device including a memory and at least one processor; and

a program stored in the memory that, when executed by the processor, presents a user interface that guides a user through the planning of the treatment procedure, the user interface including;

a treatment zone setting view presenting at least one slice of a 3D reconstruction generated from CT image data including a target, the treatment zone setting view further presenting a treatment zone marker defining a location and a size of a treatment zone, the treatment zone setting view configured to adjust the treatment zone marker in response to a received user input; and

a volumetric view presenting a 3D volume derived from the 3D reconstruction and a 3D representation of the treatment zone marker relative to structures depicted in the 3D volume.

2. The system according to claim 1, wherein the 3D representation of the treatment zone marker in the volumetric view is a wireframe.

3. The system according to claim 1, wherein the 3D volume is centered on one of the target, a target marker, the treatment zone marker, or a distal portion of an instrument.

4. The system according to claim 1, wherein the 3D volume is rotatable in response to a received user input.

5. The system according to claim 1, wherein the 3D volume has a shape selected from the group consisting of, a cubic shape, a rectangular shape, a pyramid shape, and a spherical shape.

6. The system according to claim 1, wherein the at least one slice of the treatment zone setting view includes a representation of an instrument, and wherein an orientation and a position of the representation of the instrument is adjustable in response to a received user input to adjust an orientation and position of the treatment zone marker in the treatment zone setting view.

7. The system according to claim 6, wherein the volumetric view further presents a 3D representation of the instrument, and wherein adjustment of the orientation and position of the representation of the instrument in response to the received user input in the treatment zone setting view also adjusts a corresponding orientation and position of the 3D representation of the instrument and the orientation and position of the 3D treatment zone marker in the volumetric view.

8. The system according to claim 6, wherein the representation of the instrument in the at least one slice of the treatment zone setting view includes a depth marker slidably disposed thereon, the depth marker slidable to set a depth of insertion of the instrument in response to a received user input.

9. A non-transitory computer-readable storage medium encoded with a program that, when executed by a processor, causes the processor to perform the steps of:

presenting at least one slice of a 3D reconstruction generated from CT image data including a target;

presenting a treatment zone marker defining a location and a size of a treatment zone on the presented at least one slice of the 3D reconstruction;

presenting a 3D volume derived from the 3D reconstruction; and

presenting a 3D representation of the treatment zone marker relative to structures depicted in the 3D volume.

10. The non-transitory computer-readable storage medium according to claim 9, wherein the 3D representation of the treatment zone marker is a wireframe.

11. The non-transitory computer-readable storage medium according to claim 9, wherein the 3D volume is centered on one of the target, a target marker, the treatment zone marker, or a distal portion of an instrument.

12. The non-transitory computer-readable storage medium according to claim 9, wherein the computer program further causes the processor to rotate the 3D volume in response to a received user input.

13. The non-transitory computer-readable storage medium according to claim 9, wherein the 3D volume has a shape selected from the group consisting of, a cubic shape, a rectangular shape, a pyramid shape, and a spherical shape.

14. The non-transitory computer-readable storage medium according to claim 9, wherein the computer program further causes the processor to present a representation of an instrument in the at least one slice of the 3D reconstruction, to adjust an orientation and a position of the representation of the instrument in response to a received user input, and to adjust an orientation and a position of the treatment zone marker in the at least one slice of the 3D reconstruction in response to adjustment of the orientation and position of the representation of the instrument.

15. The non-transitory computer-readable storage medium according to claim 14, wherein the computer program further causes the processor to present a 3D representation of the instrument relative to structures depicted in the 3D volume, and to adjust an orientation and a position of the 3D representation of the instrument and the 3D representation of the treatment zone marker in response to adjustment of the orientation and position of the representation of the instrument and the orientation and position of the treatment zone marker in the at least one slice of the 3D reconstruction.
