Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1\. Objectives

1. Assess the feasibility of performing MRI scans in the treatment position for accurate treatment planning and dose delivery in spinal stereotactic body radiation therapy (spinal SBRT).
2. Characterize the improved accuracy of image fusion between MRI and CT and its dosimetric impact when performing MRI scans in treatment position in spinal SBRT.
3. Assess the ability of MRI simulation to accurately target extended spinal targets beyond the current targeting limitations (\>3 consecutive vertebral body levels)
4. Optimize the workflow of using MRI simulation in treatment planning and dose delivery.
