Precision 3D Biopsy Scan and Guidance

2. 3D Ultrasound Scan

Ultrasound Scan
  • Prostate is scanned using our unique ultrasound technology
  • Motorized sensor rotates the ultrasound array within the probe’s housing
  • 3D prostate scan in recorded in less than 3 seconds

3. Biopsy Guidance

Biopsy Guidance
  • A 3D model of the prostate is generated
  • Segmented MRI is fused to ultrasound images
  • A reference volume of the prostate is displayed with MRI targets

4. 3D Cartography

  • Biopsy of the prostate is performed
  • An updated 3D ultrasound is acquired with each pass of the biopsy needle
  • Location of each biopsy core is transferred to the reference volume
  • KOELIS Trinity® builds a precise 3D map of the biopsy procedure
