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
