Biopsy planning and display apparatus
Systems are provided for managing, planning and displaying the location of biopsy core sites across multiple same-patient visits or other stored biopsy plans to increase the confidence and accuracy of biopsy results. The systems may allow the operator to fuse multiple predefined and/or automatically generated biopsy core site plans in addition to previous biopsy sites with a current prostate image to assist in creating a final new biopsy core site plan. Further, the system may allow the operator to selectively view singular parts of the final plan to simplify the planning process. Further, the systems may assist the operator during the navigation phase of the biopsy by hiding biopsy core sites from the final plan that are not of immediate interest during the biopsy phase and thereby reducing clutter and distraction during biopsy sample acquisition.
1. A method for use in a computer system associated with a medical imaging device for use in prostate biopsy planning and targeting, comprising:
accessing, from an electronic database, a previously stored prostate first image with biopsy information, said biopsy information including biopsy core sample information for previously taken biopsy core samples, said biopsy core sample information including bio; core sample locations and pathological information including locations of any cells of interest along the lengths of said biopsy core samples;
obtaining a current second image of a prostate of a patient;
registering the first and second images to identify a transformation between the images;
incorporating said biopsy information from said first image into said second image to generate a composite image, wherein said transformation is applied to said biopsy information to transform said biopsy information into a frame of reference of said second image; and
outputting said composite image to a display device.
2. The method of claim 1 , further comprising:
receiving at least one user selected biopsy site and incorporating said user selected biopsy sites into said composite image.
3. The method of claim 2 , further comprising:
after incorporating the at least one user selected biopsy site into the composite image, removing at least a portion of said biopsy information from said composite image to generate a biopsy guidance image.
4. The method of claim 1 , further comprising accessing first and second stored prostate plans from said electronic database and incorporating said first and second stored prostate plans into said composite image. wherein at least one of said first and second stored prostate plans is selected from a group consisting of:
a predefined biopsy plan identifying one or more biopsy sites;
statistical information identifying location specific information for one or more areas of a prostate; and
an elastographical biopsy plan identifying one or more biopsy sites.
5. The method of claim 4 , wherein information associated with said stored prostate plans is displayed having a unique identifier, the unique identifier including a unique symbol.
6. The method of claim 4 , further comprising:
providing to a user a menu of available prostate plans; and
receiving user inputs identifying said first and second prostate plans.
7. The method of claim 4 , further comprising:
creating a current biopsy plan;
adding at least one target biopsy site from one of said first and second stored prostate plans to said current biopsy plan; and
using said current biopsy plan to guide a biopsy procedure.
8. The method of claim 7 , wherein an identifier displayed on said composite image of said at least one target biopsy site changes from an identifier associated with said one of said first and second stored prostate plans to an identifier associated with said current biopsy plan when said at least one target biopsy site is added to said current biopsy plan.
9. The method of claim 4 , further comprising:
creating a current biopsy plan;
adding all target biopsy sites from at least one of said first and second stored prostate plans to said current biopsy plan;
removing at least one target biopsy site from said current biopsy plan; and
using said current biopsy plan to guide a biopsy procedure.
10. The method of claim 1 , wherein said pathological information includes locations of cancer cells along the length of said biopsy core samples.
