Rules for Automatic Outlining of CTVs in Spine Planning Procedures
The automatic generation of a clinical target object follows these rules:
|When the GTV||involves the unilateral pedicle,||then||the pedicle and ipsilateral transverse/lamina||are included in the CTV.|
|involves the spinous process,||the entire spinous process and bilateral laminae|
|involves the vertebral body and bilateral pedicle/transverse processes,||the entire vertebral body, bilateral pedicles, transverse process/laminae and spinous process|
|involves the vertebral body and one unilateral pedicle,||the entire vertebral body, pedicle and ipsilateral transverse process/laminae|
|involves a unilateral lamina,||the lamina/transverse process, the ipsilateral pedicle and the spinous process|
- When the intersection between the GTV and one sector is not empty, this sector is included in the CTV.
- When changes occur to the GTV, the sector selection dynamically updates.
- Every change to the GTV triggers a CTV update except for changes to the name, color or comments.
