Haptic Palpation for the Femoral Pulse in Virtual Interventional Radiology

Interventional radiology is a rapidly expanding speciality using minimally invasive techniques to treat a multitude of clinical problems. Current work in progress aims to create an affordable virtual training tool to reduce training times and patient risk during a trainee practitioners learning cycle. The procedure of arterial catheterisation has been broken down into a number of subtasks, one of which requires an operator to locate the femoral artery pulse by palpation. This is performed in preparation for a needle insertion to allow the entry of a guide wire and catheter into the patient. This paper presents the current state of research into a unique solution for affordable haptic simulation of pulse palpation in a virtual environment.
