Features

Simplify prostate biopsy imaging with bkFusion's effortless workflow

bkFusion revolutionizes biopsies with advanced visualization, seamless operation, and effortless imaging.

Reliable results

Trustworthy biopsy results with advanced visualization

With bkFusion, confidently target your biopsy with clear visualization of organ borders to detect registration errors or deformations in real-time. bkFusion, MRI-ultrasound fusion biopsy solution features proprietary imaging algorithms developed with high spatial, temporal, and contrast resolution for advanced visualization.

bkFusion has proven to accurately detect 84% of PIRADS 3-5 lesions and up to 81% GG>=2 cancer.¹

Seamless operation

Fast, seamless operation with integrated technology

With bkFusion, complex doesn’t have to be complicated. bkFusion biopsies have been recorded to be as fast as seven minutes.² The completely integrated, single-operator solution enables seamless and efficient use by a urologist, maintaining control throughout the procedure.

Effortless imaging

Effortless imaging with no calibration or 3D sweeps

bkFusion makes prostate biopsy imaging effortless with no additional steps or disruptions to the familiar biopsy workflow. No need to calibrate the system or perform 3D sweeps. Experience this easy guided workflow in the OR or clinic. Differences in patient positioning during MRI acquisition and biopsy can result in one in six lesions being reported in a different sector than they appear during US-guided biopsy.³ bkFusion's innovative Predictive Fusion® technology optimally reorients the supine MRI into LLD or lithotomy position, preventing registration errors before the procedure begins.

Predictive Fusion®

Enhance biopsy accuracy with Predictive Fusion®

Predictive Fusion® is the proprietary registration method allowing you to imediately see any errors in the overly of MRI and ultrasound images before and during the procedure. Utilizing rigid 2D slice registration, it eliminates distortion in merging 3D shapes, ensuring precise MRI-ultrasound fusion. If changes are needed, make simple, one-touch, micro-adjustments to updte the registration without calibration steps or 3D sweeps. Enhance your prostate biopsy accuracy with this advanced technology.

Biopsy techniques

Explore versatile biopsy techniques with bkFusion

bkFusion evolves with your practice, offering transperineal stabilized and freehand, or transrectal endfire and sidefire techniques, supported by sterilizable transducers. The TP approach reduces infection risk and suits office or OR settings, showing high patient tolerability and negligible infection rates. Choose between freehand or stabilized approaches, with flexibility for office or OR settings.

Freehand transperineal biplane transducer

Achieve precise biopsies with the transperineal biplane transducer and navigation sensor. Requires electromagnetic (EM) tracking.

Stabilized transperineal biplane transducer

Achieve precise biopsies with the stabilized transperineal biplane transducer and CIVCO EX3 Stepper.
