Method and system for performing biopsies
First Claim
1. A method of using a tracking system for performing a biopsy, the method comprising acts of:
- providing a probe with a deployable biopsy needle;
acquiring diagnostic images of a target region including a biopsy site;
registering the tracking system with the diagnostic images;
obtaining ultrasound images of the target region during the biopsy;
the tracking system acquiring tracking information for a location of at least one of the biopsy needle and the probe during the biopsy;
marking the location at the biopsy site on the ultrasound images; and
transforming the location at the biopsy site from the ultrasound images to the diagnostic images based on the tracking information and the registration of the tracking system with the diagnostic images.

Abstract
A method and system for performing biopsies can include an imaging system for obtaining diagnostic images of a target region; a tracking system; a probe having a deployable biopsy needle for performing a biopsy procedure where the tracking system generates tracking information for at least one of the probe and the biopsy needle; an ultrasound imaging system for obtaining ultrasound imaging of the target region; and a computer in communication with the tracking system, the imaging system and the ultrasound imaging system. The computer can register the tracking system with the imaging system. The computer transfers a marking of a biopsy site associated with the biopsy procedure from the ultrasound imaging to the diagnostic images based on the tracking information and the registration of the tracking system with the diagnostic images.

9. A non-transitory computer-readable storage medium for storing computer-executable code configured to cause a computing device in which the computer-readable storage medium is loaded to execute a method of using a tracking system for performing a biopsy, the method comprising acts of:
-
acquiring diagnostic images of a target region including a biopsy site; registering the tracking system with the diagnostic images; obtaining ultrasound images of the target region during the biopsy; the tracking system acquiring tracking information for a location of at least one of the probe, the biopsy needle and the needle guide during a biopsy; and transferring a marking of the location at the biopsy site from the ultrasound images to the diagnostic images based on the tracking information and the registration of the tracking system with the diagnostic images. - View Dependent Claims (10, 11, 12, 13, 14)

15. A biopsy system comprising:
-
an imaging system for acquiring diagnostic images of a target region including a biopsy site; a probe having a deployable biopsy needle for performing a biopsy procedure; a tracking system for acquiring tracking information for a location of at least one of the probe and the biopsy needle; an ultrasound imaging system for obtaining ultrasound images of the target region; and a computer in communication with the tracking system, the imaging system and the ultrasound imaging system, configured the tracking system with the diagnostic images acquired by the imaging system, and configured to transfer a marking of the location at the biopsy site associated with the biopsy procedure from the ultrasound images to the diagnostic images based on the tracking information and the registration of the tracking system with the diagnostic images. - View Dependent Claims (16, 17, 18, 19, 20)
