Needle insertion technique is a common minimally invasive operation, which has received a great deal of interest recently among physicians. This innovative technique is being used in many diagnoses and interventions inside the human body; among them are drug delivery, thermal ablation, tissue biopsy, and brachytherapy. The success of such procedures highly depends on the accuracy of needle tip placement and its navigation within the tissue. As of today, tremendous efforts have been made to investigate the involved factors that potentially can benefit the procedure.
Many researchers have proposed diverse types of needle designs to improve the needle tip placement. Using an asymmetric bevel-tip is the most common method, which greatly enhances the needle's maneuverability [1]. Several studies demonstrated that the needle naturally bends due to the unbalanced forces acting on its tip. Some researchers [2] used different speeds for insertion to guide the needle to...
