Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Biomedical Engineering

Background:

  • Percutaneous punctures under computed tomography (CT) guidance commonly use a freehand technique.
  • Accuracy in freehand needle placement heavily relies on the radiologist's expertise, especially in challenging procedures.

Purpose of the Study:

  • To develop and evaluate a miniature, lightweight guidance device for CT-guided percutaneous punctures.
  • To assist radiologists in achieving precise needle placement during interventional procedures.

Main Methods:

  • The device employs an accelerometer to measure needle tilt and orientation angles.
  • An alignment process matches the device's coordinate system with CT imaging software.
  • Evaluation involved phantom studies and ex vivo trials on swine cadavers for facet joint punctures.

Main Results:

  • The sensor, weighing approximately 11g, can be attached to the puncture needle.
  • A graphical user interface provides real-time visual orientation guidance.
  • Phantom experiments demonstrated low angular differences for in-plane and out-of-plane punctures.

Conclusions:

  • The developed device shows promise in assisting radiologists during CT-guided percutaneous punctures.
  • It facilitates high-precision needle navigation, potentially improving procedural outcomes.
