Robotic Precision for Prostate Disease Management

The iSR’obot™ Mona Lisa is a robotic platform for transperineal prostate biopsy that combines MRI-ultrasound fusion imaging with automated needle guidance. Designed for accurate, reproducible sampling — including hard-to-reach apex, anterior and peripheral zones — Mona Lisa supports targeted, saturation, and systematic biopsy approaches through just two skin puncture points.

Robotic accuracy for needle positioning and depth control

Mona Lisa’s navigation system delivers precise needle positioning and depth control, supporting fast and accurate biopsy collection, including challenging apex, anterior and peripheral regions.

Enhanced stability and reduced prostate deformation

A purpose-designed probe sheath allows the ultrasound probe to move unobstructed while keeping the prostate stable. Reduced gland deformation means the planned core location matches the actual tissue location at the moment of sampling – preserving the targeting accuracy established at planning.

Innovative dual-cone approach for improved access

Mona Lisa’s dual-cone design minimises pubic arch interference by creating two virtual pivot points – allowing the full sampling plan to be executed through just two skin puncture points, regardless of patient anatomy. The result is comprehensive prostate coverage with minimal perineal trauma.

Flexible and efficient biopsy planning

The automated yet flexible biopsy planning system allows urologists to easily customise biopsy plans. The urologist retains full control – core locations can be added, adjusted or removed at any stage of the procedure.

Real-time MRI and ultrasound fusion imaging

Elastic fusion of pre-operative MRI and live ultrasound imaging provides clinicians with detailed 3D visualisation, supporting precise targeting of regions of interest.

Further Capabilities

• Needle deflection adjustment
  Single-click compensation when tissue density or needle bevel deflects the needle off-target. The urologist re-inserts and reaches the planned position — no re-planning required.
• Comprehensive reporting
  Core positions are recorded automatically during the procedure. The completed report includes 3D imaging, the biopsy plan, and core-by-core data — supporting MDT review, repeat biopsy planning, and focal therapy guidance.

Simple Workflow

Biopsy planning and execution

1. Scan and model

• MRI scans are imported by the radiologist into the UroFusion software to create a prostate model and identify regions of interest (ROI).
• Ultrasound images are automatically captured via the motorised robotic arm.
• The urologist maps the prostate on the ultrasound images to enable 3D reconstruction.

2. Fuse and plan

• UroBiopsy software instantly fuses the MRI and ultrasound 3D models.
• Targeted and saturation biopsy plans automatically generate core locations based on the ROI and prostate 3D model, with systematic biopsy planning options also available.

3. Biopsy and report

• The robotic arm guides precise needle positioning according to the physician-approved biopsy plan.
• The physician inserts the needle through the robotic guide.
• Comprehensive reports, including clinical data and 3D imaging, are automatically generated.
