MRI-Compatible Pneumatic Actuation Unit for a Self-Propelling Needle

Focal laser ablation is a new, promising method to treat tumors. The current focal laser ablation approach is to insert an optical fiber into the patient using rigid needles. A side effect of this approach is that during the needle insertion, tissue damage occurs. The larger the diameter of the needle, the more tissue damage. If the diameter of...

MRI-Ready Actuation System for a Self-Propelling Needle: A Design and Experimental Approach

Standard treatment methods for prostate cancer often result in side-effects because of damage to the surrounding tissue. Magnetic resonance imaging (MRI) guided focal laser ablation to treat prostate cancer reduces the risk of adverse effects by preserving noncancerous tissue. Prostate cancer diagnosis and focal laser ablation treatment both...
