“…The first studies of robot-assisted puncture in brachytherapy were conducted by Okamura et al and Van Gellekom et al [16,22]. Since then, several studies regarding robot-assisted interstitial brachytherapy have been reported [7,12,13,24,25].…”

By employing a prostate model, we showed for the first time that robot-assisted needle placement for HDR brachy-therapy is significantly more precise than the conventional method at a velocity of 2.7 mm/s. The robot-assisted needle positioning technique improves the degree of freedom by providing additional oblique insertion channels and could be potentially exploited not only for LDR but also for HDR brachytherapy.

“…Alternatively, a single needle can be used to place all seeds according to a treatment plan [23]. In this case, the needle is sequentially placed at the desired seed locations and the radioactive seed is deployed through the cannula of the needle.…”

The paper presents a robotic method of performing low dose rate prostate brachytherapy under magnetic resonance imaging (MRI) guidance. The design and operation of a fully automated MR compatible seed injector is presented. This is used with the MrBot robot for transperineal percutaneous prostate access. A new image-registration marker and algorithms are also presented.The system is integrated and tested with a 3T MRI scanner. Tests compare three different registration methods, assess the precision of performing automated seed deployment, and use the seeds to assess the accuracy of needle targeting under image guidance. Under the ideal conditions of the in vitro experiments, results show outstanding image-guided needle and seed placement accuracy.

“…Before we close our discussion on MRI-based methods, it should be noted that currently MRI-based techniques are in use for PCa computer-aided treatment procedures such as: MRI-guided radio-frequency thermal ablation of PCa (Fei et al 2003(Fei et al , 2004, planning of the radiotherapy treatment and quality control of the correct placement of radioactive seeds in prostate brachytherapy (postimplant dosimetric analysis) (Van Gellekom et al 2004;Prete et al 1998;Susil et al2004). Therapeutic methods are beyond the scope of the present survey.…”
