Abstract

It is an object of the invention to provide for a system that can be used to improve a cancer related clinical workflow compared to the current cancer related clinical workflow. This object is achieved by an image guided system configured for supporting a combined biopsy and treatment procedure using image guidance to bring a needle from a defined location to a predetermined end location in a subject of interest. The image guidance system comprises a medical imaging system ( 580 ) configured for acquisition of medical images of a region of interest ( 403 ) in the subject of interest, wherein the medical images are used to determine a current position of the predetermined end location ( 404 ). The image guidance system further comprises needle guidance system ( 402, 403 ) configured for defining a needle position in space and thereby defining the defined location ( 405, 406 ) and configured for guiding a biopsy and treatment needle into the region of interest. The image guidance system also comprises a user interface system ( 530 ) configured for supporting both the biopsy and treatment procedure, such that a patient setup needs to be executed only once. The user interface system ( 530 ) comprises a calibration unit ( 540 ) for aligning the needle guidance system ( 402, 403 ) with the medical images.

First claim

The invention claimed is:

1. An image guidance system configured for supporting a combined biopsy and treatment procedure using image guidance to bring a needle from a defined location to a predetermined end location in a subject of interest, the image guidance system comprising:
a medical imaging system configured for acquisition of medical images of a region of interest in the subject of interest, wherein the medical images are used to determine a current position of the predetermined end location;
a needle guidance system configured for defining a needle position in a space and thereby defining the defined location, and configured for guiding the needle into the region of interest; and
a user interface system configured for supporting the combined biopsy and treatment procedure, such that a patient setup needs to be executed only once for both the biopsy and the treatment in the combined biopsy and treatment procedure,
wherein the image guidance system determines calibration setting for aligning the needle guidance system with the medical images prior to the biopsy, and
wherein the image guidance system is further configured to automatically use, during the treatment, the calibration settings determined prior to the biopsy.

2. The image guidance system of claim 1 , further configured to store position information for one or more biopsy locations and one or more treatment locations in a same coordinate space.

3. An image guidance system of claim 1 , configured to create a treatment plan, such that a trajectory used during biopsy can be reused during treatment.

4. The image guidance system of claim 1 , wherein the image guidance system is further configured for registering a planning image based on which the predetermined end location is determined with at least one of the medical images.

5. The image guidance system of claim 1 , configured to generate a first report and a second report about the combined biopsy and treatment procedure, wherein the first report comprises different information than the second report.

6. The image guidance system of claim 1 , wherein the image guidance system is further configured for enabling delineation of a region of interest.

7. The image guidance system of claim 1 , wherein the image guidance system is further configured to create a treatment plan based on a biopsy result.

8. The image guidance system of claim 1 , wherein the system is arranged to operate with a photonic needle as the biopsy needle.

9. The image guidance system of claim 1 , configured to create multiple treatment plans and configured to allow a selection of one of the treatment plans based on a biopsy result.

10. The image guidance system of claim 5 , wherein the first report is a biopsy report which includes first information pertaining to the biopsy, and wherein the second report is a treatment report which includes second information pertaining to the treatment.

11. The image guidance system of claim 10 , wherein the first information identifies locations where the biopsy was taken, and wherein the second information includes at least one treatment dose volume histogram.

12. A method of supporting a combined biopsy and treatment procedure using image guidance to bring a needle from a defined location to a predetermined end location in a subject of interest, the method comprising:
acquiring medical images of a region of interest in the subject of interest;
determining a current position of the predetermined end location from the medical images;
defining a needle position in a space and to define the defined location;
guiding the needle into the region of interest;
executing with a user interface system a patient setup only once for both the biopsy and the treatment in the combined biopsy and treatment procedure;
determining calibration settings for aligning the needle guidance with the medical images prior to the biopsy; and
automatically using, during the treatment, the calibration settings determined prior to the biopsy.

13. The method of claim 12 , further comprising storing position information for one or more biopsy locations and one or more treatment locations in a same coordinate space.

14. The method of claim 12 , further comprising creating a treatment plan, such that a trajectory used during biopsy can be reused during treatment.

15. The method of claim 12 , further comprising registering a planning image based on which the predetermined end location is determined with at least one of the medical images.

16. The method of claim 12 , further comprising generating a first report and a second report about the combined biopsy and treatment procedure, wherein the first report comprises different information than the second report.

17. The method of claim 12 , further comprising delineating a region of interest.

18. The method of claim 12 , further comprising creating a treatment plan based on a biopsy result.

19. The method of claim 12 , further comprising operating with a photonic needle as the biopsy needle.

20. The method of claim 12 , further comprising creating multiple treatment plans and allowing a selection of one of the treatment plans based on a biopsy result.

21. An image guidance system configured for supporting a combined biopsy and treatment procedure, the image guidance system comprising:
a needle guidance system configured for defining a needle position in a space and thereby defining the defined location, and configured for guiding the needle into a region of interest indicated in a medical image; and
a user interface system configured for supporting the combined biopsy and treatment procedure, such that a patient setup needs to be executed only once for both the biopsy and the treatment in the combined biopsy and treatment procedure,
wherein the image guidance system determines calibration settings for aligning the needle guidance system with a medical image prior to the biopsy, and
wherein the image guidance system is further configured to automatically use, during the treatment, the calibration settings determined prior to the biopsy.

22. A method of supporting a combined biopsy and treatment procedure using image guidance to bring a needle from a defined location to a predetermined end location in a subject of interest, the method comprising:
determining a current position of the predetermined end location from a medical image;
defining a needle position in a space and to define the defined location;
executing with a user interface system a patient setup only once for both the biopsy and the treatment in the combined biopsy and treatment procedure;
determining calibration settings for aligning a needle guidance with a medical image prior to the biopsy; and
using, during the treatment, the calibration settings determined prior to the biopsy.
