Table 1 Requirements for safety
From: Making the right software choice for clinically used equipment in radiation oncology
Data import, data registration and structure contouring | ||
|---|---|---|
Minimal | Enhanced | Optimal |
Import of all CT data with dicom coordinates | Import of all CT data with transposition of the dicom coordinates (lower error source) | Structures can be digitally locked by selected users |
Import and export of treatment plans in dicom format | Registration based on dicom coordinates | |
Registration is digital lockable | ||
Structures, which are connected to a treatment plan, can’t be changed (only copies or new structures can be created) | ||
Requirements for treatment planning | ||
Minimal | Enhanced | Optimal |
Collapse cone or equivalent algorithm for the dose calculation of photons | Monte Carlo or equivalent algorithm for the dose calculation of photons | IMRT optimization with Monte Carlo or equivalent algorithm |
Monte Carlo based radiation head model | IMRT optimization with a Collapse cone or equivalent algorithm | Conventional IMRT optimization comprises collimator and gantry rotation |
Create sum plans of treatment plans calculated on rigid registered data sets | IMRT optimization with a direct aperture calculation | Volumetric IMRT optimization comprises collimator rotation and segment selection |
Comparison of different treatment plans (calculated on any data sets) with simultaneous display of the isodose distributions, DVH and BEV | Monte Carlo or equivalent algorithm for the dose calculation of electrons | Creating of optimal DRR (DRR templates producible and manual adjustable) |
Creation of check sum every working day (control of beam data) | More than one reference dose and point can be applied to a treatment plan (e.g. integrated boost) | |
Requirements for ROKIS | ||
Minimal | Enhanced | Optimal |
Import and export of all data in general readable dicom format (structures, treatment plans, CT/MRI/PET/… data sets, isodoses, verification images such as planar view images or CBCT data) | Treatment plans can be digitally locked by selected users | Automatic connection between patient, prescription treatment plan and verification images |
Automatic link of the treatment plan to the corresponding patient | Unlocked treatment plans can’t be applied to a patient | |
Automatic link of the treatment plan to the corresponding target volume or clinical protocol respectively | ||
After radiation the treatment plan can’t be changed or deleted (only copies can be made) | ||
Positioning information is linked to the treatment plan | ||
Positioning information and patient photo can be displayed in the treatment room | ||
Remote control | ||
Periodical upgrades available, (with no data loss, for example user defined templates) | ||
High data integrity | ||
Requirements for patient verification | ||
Minimal | Enhanced | Optimal |
Automatic calculation of the 3D correction vector of the treatment table (2D planar images and CBCT) | Automatic link of the verification images to the corresponding field of the treatment plan | Manual adjustment of the field edges of the verification field always possible |
Automatic correction of the table by the system | ||
Automatic link of the verification images to the corresponding treatment plan and patient | ||
Correction data from offline analysis is automatically sent to the treatment system | ||
