Fusion Bx is intended for use by physicians for enhanced visualization of ultrasound imaging of the prostate in clinic and hospital settings. It provides 2D and 3D image visualization including review, manipulation, and analysis tools. Additional features include patient data management, multiplanar reconstruction, 3D image registration, segmentation, image annotation, and to record the biopsies were acquired during the procedure.

Fusion Bx is designed to display the 2D live video received from commercially available ultrasound machines and use this 2D video to reconstruct a 3D ultrasound image volume. The system is designed to work with clinicians' existing ultrasound machines, transrectal ultrasound (TRUS) probes, commercially available needles, needle guides/templates and needle qun combination. Additional software features include patient data management, multi-planar reconstruction, segmentation, image measurements and 3D image registration. The device will assist clinicians in planning and performing image-guided interventional procedures such as biopsies and placing instruments in the prostate for adult men with suspected prostate cancer. Fusion Bx is comprised of a laptop-based workstation and a hardware assembly. The included hardware consists of a frame grabber, encoder converter, hardware arm (comprising of a swing arm, counterbalance, tracker and stepper), and stand. The stepper holds the ultrasound probe and measures probe position while the physician performs a normal ultrasound imaging procedure of the subject prostate. Encoders in the stepper and tracker send joint movement procedure of the computer workstation which tracks probe position and orientation. Control of imontation to the oomputer wonetation tem is done manually by the physician, just as it would the altrasound probo and all.recome eyer, by tracking the position and orientation of the be in the absento of Pacion and in a video image, the workstation is able to reconstruct and ultiasound probe while capturing the nace integor ... o the prostate and to display the live image position within the prostate. The computer workstation is connected to the ultrasound system via a cable and hardware The computer workstation to connected to a stream 2D ultrasound image into a format that is device that converts the rour time track can be marked up with gland readable by T dolon DX. The roometrations in ages of the patient's prostate can be Segmentation of other manch in the principle that features of the prostate can be visualized consistently with a number of imaging modalities. The physician may attach a commercially available biopsy needle guide to the TRUS probe and The privsician may uttain a sommercially at the prostate biopsy procedure. During the biopsy use the probe and blopsy noodio to personn are process visible on the Fusion Bx display.

As the probe and needle guide are maneuvered by the acquired duling the probe is tracked. Needle tracked. Needle trajectory is estimated by physion, the poolion and onehative to the 3D image stack. This information is provided so the physician can assess prostate abnormalities, plan and implement biopsy procedures. Supported imaging modalities include DICOM images and real-time 2D ultrasound images.

In summary, Fusion Bx offers the physician additional 3D information for assessing prostate n summally, I dolon DX onero the procedures.

This system will not prevent the clinician from using the standard ultrasound equipment.
