Augmented reality (AR) visualization is feasible for computed tomography (CT)-guided procedures. This technology enabled accurate targeting of simulated liver lesions in a phantom study, demonstrating its potential for interventional radiology.

Area of Science:

  • Medical imaging and visualization
  • Interventional radiology
  • Augmented reality applications

Background:

  • Computed tomography (CT)-guided interventions are crucial for diagnosing and treating various conditions.
  • Accurate needle placement is critical for the success and safety of CT-guided procedures.
  • Existing methods may face challenges in real-time visualization and guidance during interventions.

Purpose of the Study:

  • To assess the feasibility and performance of an augmented reality (AR) visualization prototype.
  • To evaluate AR guidance for virtual CT-guided interventional procedures.
  • To test AR accuracy in targeting simulated liver lesions within a multimodality abdominal phantom.

Main Methods:

  • Three radiologists performed 30 biopsy needle targeting attempts on simulated liver lesions (5-15 mm) using AR guidance.

  • Procedures were conducted in a multimodality abdominal phantom.
  • Needle tip position relative to the lesion was verified using ultrasonography and CT.

    • Main Results:

    • Augmented reality (AR) guidance facilitated successful targeting of all simulated liver lesions on the first needle pass.
    • The AR visualization prototype demonstrated intuitive and accurate lesion targeting capabilities.
    • No significant discrepancies were noted in lesion targeting accuracy with AR assistance.

    Conclusions:

    • Augmented reality (AR) visualization is a feasible tool for CT-guided interventional procedures.
    • AR guidance offers intuitive and accurate targeting of simulated lesions in a phantom model.
    • This technology holds promise for enhancing precision and potentially improving outcomes in interventional radiology.
