Table 5 Requirements for respiratory gating
From: Making the right software choice for clinically used equipment in radiation oncology
Requirements for accuracy | ||
|---|---|---|
Minimal | Enhanced | Optimal |
Planning system supports 4D-CT data sets | IMRT technique used can be applied in gated mode | Automatic propagation of the structures between the different phases |
Planning system supports the localizer used | Patient verification can be done with respiratory gating (CBCT) | Patient verification can be done with 4D-CBCT |
Planning system supports amplitude gating and phase gating | Registration of 4D planning-CT with 4D-CBCT is possible | |
Register of diagnostic data sets to the 4D data set is possible | ||
Planning system can create an ITV out of GTV’s contoured in different phases | ||
Structure copy from one to another phase is possible | ||
Patient verification can be done with respiratory gating (2D planar radiographics) | ||
Data transfer of the chosen gating window possible between CT, planning system and treatment system | ||
