Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Surgical Technology

Background:

  • Current imaging techniques often require patient repositioning between diagnosis and intervention.
  • Mobile C-arms offer flexibility but typically lack advanced 3D soft tissue imaging capabilities.
  • Integrating real-time imaging directly into surgical workflows is a significant challenge.

Purpose of the Study:

  • To introduce and evaluate a clinical prototype for 3D soft tissue imaging using a mobile C-arm.
  • To demonstrate the feasibility and potential applications of this technology in clinical settings.
  • To assess the benefits of enhanced intraoperative imaging for patient care.

Main Methods:

  • Development of a clinical prototype 3D soft tissue imaging system based on a mobile C-arm.

  • Acquisition of initial clinical images from animal and human subjects, including dosimetry measurements.
  • Demonstration of image fusion capabilities with standard diagnostic imaging modalities (MRI, CT, PET).

    • Main Results:

    • Successful implementation of a mobile 3D C-arm prototype for soft tissue imaging.
    • Acquisition of preliminary clinical images, validating the system's performance.
    • Demonstration of effective image fusion, integrating diagnostic and intraoperative data.

    Conclusions:

    • The mobile 3D C-arm prototype offers a flexible solution for intraoperative soft tissue imaging.
    • This technology enhances patient access and potentially reduces the need for repositioning.
    • Promising applications include image-guided brachytherapy, radiofrequency thermal therapy, and other interventions.
