Table 1 Overview of verifications throughout the treatment workflow. In case a verification fails, the patient is transferred from the MRI-only workflow to the standard workflow based on CT
From: “sCT-Feasibility” - a feasibility study for deep learning-based MRI-only brain radiotherapy
No. | Verification criterion |
|---|---|
1 | Can the sCT be generated and is the sCT clinically utilizable? |
2 | Are the three rotations needed for CT-MRI registration each ≤ 3°? |
3 | Can a treatment plan be generated and verified using the sCT? |
4 | Is the dosimetric difference between sCT- and CT-based treatment plans in the PTV ≤ 3%? |
5 | Is the dosimetric difference between the sCT- and CT-based treatment plans in affected OARs (receiving > 10% of prescribed dose) ≤ 3%? |
6 | Are the couch correction parameters during patient positioning in the rotational degrees of freedom ≤ 3°? |
