Area of Science:

  • Medical Imaging
  • Surgical Technology
  • Computer Vision

Background:

  • Real-time 3D ultrasound offers potential for image-guided surgery.
  • High data rates in 3D ultrasound challenge traditional instrument tracking methods.

Purpose of the Study:

  • To develop a novel, high-speed instrument tracking method for real-time 3D ultrasound-guided surgery.
  • To overcome data rate limitations of conventional tracking techniques.

Main Methods:

  • A modified Radon transform identifies instrument shaft axes in planar projections.
  • Fiducial markers are used for determining instrument rotation and tip location.
  • Graphics processing units (GPUs) are utilized for rapid computational execution.

Main Results:

  • The GPU implementation achieved surgical instrument detection in 31 ms.
  • This speed is sufficient for real-time tracking at 26 volumes/second.
  • Instrument tip position errors were less than 0.2 mm in phantom studies.
  • Successful in vivo tracking of a surgical instrument within a porcine heart was demonstrated.

Conclusions:

  • The proposed method enables accurate and rapid real-time 3D surgical instrument tracking.
  • This technique is suitable for integration with current 3D ultrasound systems.
  • The findings support the advancement of image-guided surgical procedures.
