A miniature accelerometer-based guidance device for percutaneous computed tomography-guided punctures
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 radiologists experience. Thus, a miniature lightweight guidance device was developed which is capable of assisting a radiologist during the needle placement process.
