An augmented reality-guided biopsy system using a high-speed motion tracking and real-time registration platform.

Area of Science:

• Medical Technology
• Surgical Innovation
• Diagnostic Imaging

Background:

• Biopsies are essential for diagnosing diseases, including cancers.
• Current biopsy techniques can face challenges in targeting accuracy.
• Enhanced visualization is crucial for improving procedural outcomes.

Purpose of the Study:

• To develop and evaluate an augmented reality (AR) system for improving biopsy procedures.
• To enhance the targeting accuracy of biopsies, particularly for prostate cancer diagnosis.
• To integrate preoperative imaging with real-time guidance for minimally invasive procedures.

Main Methods:

• Development of an AR system utilizing high-speed motion tracking and an AR headset.
• Superimposition of holographic organ and lesion representations onto real-time physical views.
• Integration of preoperative scans (CT, MRI) with real-time ultrasound-guided procedures.
• Application of the system for prostate biopsy guidance.

Main Results:

• The AR-guided biopsy system demonstrated an average targeting accuracy of 2.94 ± 1.04 mm.
• The system provides enhanced real-time visualization of organs, lesions, and surrounding structures.
• Successful application in improving visualization during prostate biopsy procedures.

Conclusions:

• The developed AR system significantly enhances visualization during biopsy procedures.
• This technology offers improved targeting accuracy for prostate biopsies and potentially other biopsy types.
• AR-guided biopsy represents a promising advancement in minimally invasive diagnostic procedures.
