title: In vivo force during arterial interventional radiology needle puncture procedures.
abstract: To adequately simulate the forces generated during interventional radiological (IR) procedures, non intrusive in-vivo methods must be used. Using finger tip mounted, non intrusive capacitance force sensor pads (PPS, Los Angeles, California) we have been able to measure the forces involved in interventional radiology without a change in procedure technique. Data acquired during the process of calibration of the capacitance pads in conjunction with extensive in-vitro needle puncture force measurement using a commercially available tensile tester (Nene Industries, UK) are presented here.
