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 a processor; and

a program stored in the memory that, when executed by the processor, causes the processor to present 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 location and the size of the treatment zone defined by the treatment zone marker in response to received treatment zone marker adjustment user inputs,

wherein the treatment zone setting view includes a 2D representation of an instrument,

wherein in response to the received treatment zone marker adjustment user input an orientation and a position of the 2D representation of the instrument are adjusted relative to the at least one slice of the 3D reconstruction, and

wherein the treatment zone setting view includes a user-selectable power level setting having a corresponding predetermined size limit, and an alert is generated when the size of the treatment zone defined by the treatment zone marker is adjusted to exceed the predetermined size limit corresponding to the user-selectable power level setting; and

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

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 rendering is centered on one of the target, a target marker, the treatment zone marker, or a distal portion of the instrument.

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

5. The system according to claim 1, wherein the 3D rendering 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 volumetric view further presents a 3D representation of the instrument, and wherein the adjustment of the orientation and the position of the 2D representation of the instrument in response to the received treatment zone marker adjustment 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 the position of the 3D representation of the treatment zone marker in the volumetric view.

7. The system according to claim 1, wherein the 2D representation of the instrument in the at least one slice of the treatment zone setting view includes a depth marker slidably disposed on the 2D representation of the instrument, the depth marker slidable to set a depth of insertion of the instrument in response to a received depth user input.

8. The system according to claim 1, wherein the treatment zone setting view includes a user-selectable needle setting having a corresponding predetermined size limit and an alert is generated when the size of the treatment zone defined by the treatment zone marker is adjusted to exceed the predetermined size limit corresponding to the user-selectable needle setting.

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

presenting at least one slice of a 3D reconstruction generated from CT image data including a target in a treatment zone setting view;

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

adjusting the location and the size of the treatment zone defined by the treatment zone marker in response to received treatment zone marker adjustment user inputs,

wherein the treatment zone setting view includes a 2D representation of an instrument, and

wherein in response to the received treatment zone marker adjustment user input an orientation and a position of the 2D representation of the instrument are adjusted relative to the at least one slice of the 3D reconstruction;

presenting a user-selectable power level setting having a corresponding predetermined size limit;

generating an alert when the size of the treatment zone defined by the treatment zone marker is adjusted to exceed the predetermined size limit corresponding to the user-selectable power level setting;

presenting a 3D rendering derived from the 3D reconstruction in a volumetric view; and

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

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 rendering is centered on one of the target, a target marker, the treatment zone marker, or a distal portion of the instrument.

12. The non-transitory computer-readable storage medium according to claim 9, wherein the program is configured to rotate the 3D rendering in response to a received rotation user input.

13. The non-transitory computer-readable storage medium according to claim 9, wherein the 3D rendering 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 volumetric view further presents a 3D representation of the instrument, and wherein the adjustment of the orientation and the position of the 2D representation of the instrument in response to the received treatment zone marker adjustment 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 the position of the 3D representation of the treatment zone marker in the volumetric view.

15. The non-transitory computer-readable storage medium according to claim 9, wherein the 2D representation of the instrument in the at least one slice of the treatment zone setting view includes a depth marker slidably disposed on the 2D representation of the instrument, the depth marker slidable to set a depth of insertion of the instrument in response to a received depth user input.

16. The non-transitory computer-readable storage medium according to claim 9, wherein the program is configured to:

present a user-selectable needle setting having a corresponding predetermined size limit; and
