Abstract

A system and method for planning surgical procedure including importing CT image data of a patient; generating a 3D reconstruction from the CT image data; presenting a slice of the 3D reconstruction; selecting a target anatomical feature from the slice of the 3D reconstruction; setting a treatment zone including presenting at least one slice of the 3D reconstruction including the target anatomical feature, and presenting a treatment zone marker defining a location and a size of the treatment zone on the presented at least one slice of the 3D reconstruction; setting an access route to the treatment zone; and presenting a three-dimensional model including the treatment zone and the access route.

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 a treatment procedure, the user interface including;

a target selection view presenting a slice of a 3D reconstruction generated from CT image data of a patient, the target selection view configured to select at least one target anatomical feature from the presented slice in response to a received user input;

a treatment zone setting view presenting at least one slice of the 3D reconstruction including the target anatomical feature, 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;

an access route setting view configured to set an access route to the treatment zone in response to a received user input; and

a review view configured to present a three-dimensional model of the treatment zone and the access route.

2. The system according to claim 1, wherein one or more of the treatment zone setting view, access route setting view, and review view are presented separately.

3. The system according to claim 1, wherein at least one dimension of the treatment zone marker is adjustable in response to a received user input to adjust the size of the treatment zone.

4. The system according to claim 3, wherein the treatment zone setting view presents each of an axial slice of the 3D reconstruction, a coronal slice of the 3D reconstruction and a sagittal slice of the 3D reconstruction, and wherein the adjustment of the at least one dimension of the treatment zone marker in response to the received user input in one of the axial, coronal, and sagittal slices adjusts at least one dimension of the treatment zone marker in at least one other of the axial, coronal, and sagittal slices.

5. The system according to claim 1, wherein the treatment zone setting view further presents at least one treatment parameter value, the at least one treatment parameter value being adjustable in response to a received user input.

6. The system according to claim 5, wherein the at least one treatment parameter value is selected from the group consisting of a power setting, a duration setting, an instrument type, and a size of the treatment zone.

7. The system according to claim 5, wherein adjusting the at least one treatment parameter value automatically adjusts at least one other treatment parameter value.

8. The system according to claim 1, wherein the treatment zone is presented in the three-dimensional model as a three-dimensional treatment volume.

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:

importing CT image data of a patient;

generating a 3D reconstruction from the CT image data;

presenting a slice of the 3D reconstruction;

selecting a target anatomical feature from the slice of the 3D reconstruction in response to a received user input;

setting a treatment zone in response to a received user input including;

presenting at least one slice of the 3D reconstruction including the target anatomical feature; and

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

setting an access route to the treatment zone in response to a received user input; and

presenting a three-dimensional model including the treatment zone and the access route.

10. The non-transitory computer-readable storage medium according to claim 9, wherein setting the treatment zone includes adjusting at least one dimension of the treatment zone marker to adjust the size of the treatment zone.

11. The non-transitory computer-readable storage medium according to claim 10, wherein the treatment zone marker is presented in each of an axial slice of the 3D reconstruction, a coronal slice of the 3D reconstruction, and a sagittal slice of the 3D reconstruction, wherein adjustment of the at least one dimension of the treatment zone marker in one of the axial, coronal, and sagittal slices automatically adjusts at least one dimension of the treatment zone marker in at least one other of the axial, coronal, and sagittal slices.

12. The non-transitory computer-readable storage medium according to claim 9, wherein setting the treatment zone further includes:

presenting at least one treatment parameter value; and

adjusting the at least one treatment parameter value.

13. The non-transitory computer-readable storage medium according to claim 12, wherein the at least one treatment parameter value is selected from the group consisting of a power setting, a duration setting, and instrument type, and a size of the treatment zone.

14. The non-transitory computer-readable storage medium according to claim 12, wherein adjusting the at least one treatment parameter value automatically adjusts at least one other treatment parameter value of the treatment zone.

15. The non-transitory computer-readable storage medium according to claim 9, wherein the treatment zone is presented in the three-dimensional model as a three-dimensional treatment volume.
