The stereotactic frame was correctly fixed to the patient\u2019s skull and the table. During the seventh sonication, the patient pressed the emergency button and vomited several times. Before the eighth sonication, the patient\u2019s movement was detected and was verified on coronal images. The MR images were repeated, and the treatment was successfully completed with significant improvement in the tremors. After treatment, it was discovered that the MR table was laterally unstable due to the absence of ball bearings, which should be present on both sides of the guide rail of the MR table. The ball bearings were attached to the reverse side of the table, and the table was stabilized. Stereotactic accuracy of MRgFUS is not only ensured by rigid fixation of the stereotactic frame, but also by stability of the MR table.<\/jats:p>","DOI":"10.3171\/2020.4.jns20219","type":"journal-article","created":{"date-parts":[[2020,8,21]],"date-time":"2020-08-21T07:32:27Z","timestamp":1597995147000},"page":"1724-1727","source":"Crossref","is-referenced-by-count":0,"title":["Movement
