MRI acquisition parameter optimization workflow for both the MR-Simulator and MR-Linac.

╲	MR-Simulator	MR-Linac
→ Step 1	Slice Thickness Slice Gap	Slice Thickness Slice Gap Refocusing Flip Angle SofTone Acoustic Noise Reduction
→ Step 2	GRAPPA Factor	CS-SENSE Factor Denoising Factor
→ Step 3	Echo Time (TE)	Echo Time (TE)
→ Step 4	Number of Slices Repetition Time (TR)	Number of Slices Repetition Time (TR)
→ Step 5	Turbo Factor	TSE Factor
→ Step 6	Final Repeatability Assessment	Final Repeatability Assessment

Note that some features are available on the MR-Linac which are not for the MR-Simulator such as adjusting the refocusing flip angle and adding noise reduction techniques. Additionally, since the MR-Simulator is Siemens and the MR-Linac is Philips, they both present with different acceleration methods (GRAPPA²⁴ for Siemens and CS-SENSE²⁵ for Philips).
