Visiting Points with a Bevel-Tip Needle∗
Many surgical procedures could benefit from guiding a bevel-tip needle through a sequence of treatment points in a patient. For example, brachytherapy procedures implant radioactive seeds to treat cancer, and biopsy procedures extract tissue samples to test for cancer. A bevel-tip needle has an asymmetric tip that cuts through tissue along a circular arc. By rotating the needle during its inser...

متن کاملForce-Sensor-Based Estimation of Needle Tip Deflection in Brachytherapy
A virtual sensor is developed for the online estimation of needle tip deflection during permanent interstitial brachytherapy needle insertion. Permanent interstitial brachytherapy is an effective, minimally invasive, and patient friendly cancer treatment procedure. The deflection of the needles used in the procedure, however, undermines the treatment efficiency and, therefore, needs to be minim...
