Brief summary: This study aims to explore the safety and efficacy of eliminating the planning target volume (PTV) margins based on MRI-guided adaptive stereotactic radiotherapy for non-small cell lung cancer (NSCLC) patients with brain metastasis.

Detailed description: This study aims to explore the safety and efficacy of eliminating the planning target volume (PTV) margins based on MRI-guided adaptive stereotactic radiotherapy for NSCLC patients with brain metastasis. In this study, patients will be randomly assigned in a 1:1 ratio to the study group or the control group. Patients in the study group will receive MRI-guided adaptive stereotactic radiotherapy (SRT) (without PTV expansion margin), while patients in the control group will receive CT-guided conventional standard SRT (with PTV expansion margin). After the completion of treatment, patients will be followed up regularly to assess safety and efficacy.
