Abstract: A new spatial localization mechanism based on CT image-guided robot-assisted percutaneous lung biopsy was proposed.Firstly,six marker points are designed and fixed on the CT examination bed at the same time to reference and locate in hardware.Secondly,the improved D-H inverse motion algorithm is used in software to guide the robot to perform percutaneous lung puncture.The simulation results show that the success rate of one-time puncture can be effectively guaranteed by using the location mechanism proposed in this paper.

Key words: Robot assistant system, D-H inverse motion algorithm, Percutaneous lung biopsy
