Major Field of Science: | Engineering and Technology | Field Category: | Electrical Engineering - Electronic Engineering - Information Engineering | Keywords: | MRgFUS robotic devices;Motion accuracy;Simple evaluation methods | Issue Date: | Aug-2021 | Source: | The International Journal of Medical Robotics and Computer Assisted Surgery, 2021, vol. 17, no. 4, articl. no. e2287 | Volume: | 17 | Issue: | 4 | Journal: | The International Journal of Medical Robotics and Computer Assisted Surgery | Abstract: | Background: Roboticassisted diagnostic and therapeutic modalities require ahighly accurate performance to be certified for clinical application. In this paper,three simple methods for assessing the accuracy of motion of magnetic resonanceguided focused ultrasound (MRgFUS) robotic systems are presented.Methods: The accuracy of motion of a 4 degrees of freedom robotic systemintended for preclinical use of MRgFUS was evaluated by calliperbased and mag-netic resonance imaging (MRI) methods, as well as visually by performing multipleablations on a plastic film.Results: The benchtop results confirmed a highly accurate motion in all axes ofoperation. The spatial positioning errors estimated by MRI evaluation were definedby the size of the imaging pixels. Lesions arrangement in discrete and overlappingpatterns confirmed satisfactory alignment of motion trajectories.Conclusions: We believe the methods presented here should serve as a standard forevaluating the accuracy of motion of MRgFUS robotic systems. | URI: | https://hdl.handle.net/20.500.14279/23019 | ISSN: | 1478596X | DOI: | 10.1002/rcs.2287 | Rights: | © The Authors.
