Needle insertion is a minimally invasive medical procedure commonly used for biopsy, ablation, or deposition of therapeutic agents. In prostate brachytherapy, needles are inserted into the prostate in order to deposit multiple rice-grain-sized radioactive seeds to eradicate cancerous tissue from clo
Needle insertion is a minimally invasive procedure finding applications in biopsy, ablation, drug delivery, and cancer therapy. Prostate brachytherapy is a therapeutic procedure where radioactive agents are implanted within the prostate using long needles for the purpose of cancer irradiation. Durin
A tissue-independent model to estimate needle deflection during insertion in soft tissue is presented in this paper. A force/torque sensor is connected to the needle base in order to measure forces and moments during insertion due to needle deflection. A static mechanical model, which is based on th…
