Integration of Free-Hand 3D Ultrasound and Mobile C-Arm Cone-Beam CT: Feasibility and Characterization for Real-Time Guidance of Needle Insertion

Accurate placement of a needle or probe is a common requirement in minimally invasive interventions, pain management, and drug delivery. In brachytherapy for example, radioactive seeds need to be precisely placed within the patient to ensure correct delivery of the planned dose distribution to the tumor volume (Koukourakis et al., 2009). Various ablation techniques rely on similar accurate placement of therapeutic probes within the target – e.g., radiofrequency ablation (RFA) and cryotherapy (Tiong and Maddern, 2011).
