Abstract
Purpose
Percutaneous punctures are often performed under computed tomography (CT) guidance using a freehand method. Especially in challenging cases, initial accuracy of the needle placement is highly dependent on the radiologist’s experience. Thus, a miniature lightweight guidance device was developed which is capable of assisting a radiologist during the needle placement process.
Methods
The device utilizes an accelerometer to measure the needle’s tilt by calculating a set of orientation angles. This set can be matched with the coordinate system of the CT imaging software during a simple alignment process. After that, the needle’s orientation can be expressed in terms of projected angles in the axial and sagittal planes. The accuracy of the device was evaluated in a phantom study, and initial clinical trials were carried out performing facet joint punctures in a swine cadaver.
Results
The sensor was embedded in a cube with dimensions of \(2\,\hbox {cm} \times 2\,\hbox {cm} \times 2\,\hbox {cm}\) and a total weight of about 11 g which can be attached to the puncture needle at its rear end or handgrip. A graphical user interface (GUÌ) has been created offering visual real-time orientation guidance. Results of the phantom experiments showed differences between planned target and performed puncture angles of \(0.96^{\circ } \pm 0.76^{\circ }\) for in-plane and \(1.78^{\circ } \pm 1.37^{\circ }\) for out-of-plane punctures.
Conclusion
The results of the phantom and ex vivo study suggest that the device is useful to assist a radiologist in CT-guided percutaneous punctures and helps navigating the needle with high precision.
