Exclusion Criteria:

1. Patients with implanted pacemaker, defibrillator or deep brain stimulator, other implanted electronic devices in the brain or documented clinically significant arrhythmias. 2.

Any other condition that, in the investigator's judgment, might increase the risk to the patients or decrease the chance of obtaining satisfactory data needed to achieve the objectives of the study. 10. Abnormal baseline findings considered by the investigator to indicate conditions that might affect study endpoints. 11. Patients who have acute hemorrhage within the ROI. 12. Major surgery or significant traumatic injury that has not been recovered from by 4 weeks prior to screening, or patients who have had minor procedures, percutaneous biopsies or placement of vascular access device ≤ 1 week prior to screening, or who have not recovered from side effects of such procedure or injury. 13. Patients who have coagulopathy or risk factors for bleeding. 14. Receiving anticoagulants or antiplatelet drugs within one week before study entry. 15. Receiving medications known to increase the risk of bleeding within one month before study entry (e.g., bevacizumab) 16. Contraindications to MRI, including but not limited to metallic implants and claustrophobia. 17. Patients with severe hypertension (defined as systolic blood pressure > 180 mmHg or diastolic blood pressure >100 mmHg) 18. Patients with cardiac shunt. 19.

Arms

Experimental: FUS + re-RT or FUS + SRS

The SRS treatment will be administered for 3 consecutive days (one fraction of 7-9 Gy per day; total dose 21-27 Gy), including SRS treatment 1 (SRS 1), SRS treatment 2 (SRS 2), and SRS treatment 3 (SRS 3). At the SRS 1 and SRS 3, the patients will be shaved their hair at first, and the patient registration will be performed for the neuronavigation system according to the instruction of the system. cRT will be administered for 5 consecutive days within one week, and a full course is two weeks (one fraction of 3-4 Gy per day; total dose: 30-40 Gy), including cRT treatment 1 to cRT treatment 10 (cRT 1-cRT 10). At the cRT 1, cRT 3, cRT 6, and cRT 8, the patients will be shaved their hair at first, and the patient registration will be performed for the neuronavigation system according to the instruction of the system.
