Software, Software Modules
1. Moniqa. It is an integrated quality assurance (QA) software for plan quality, data transfer integrity and treatment consistency check. The software has multiple modules to link Monaco, RadCalc, Precision, GammaPlan and Mosaiq for treatment plan goal generation, plan quality check, independent dose verification, data transfer check, treatment verification, patient finding and report generation, etc. It has been used for each single patient by physicians, dosimetrists and physicists in radiation oncology across Froedtert health network and VA Milwaukee as well.
2. ArtQA. Used for online adaptive treatment on MR Linac to efficiently perform plan quality check, data transfer and treatment verification, and secondary dose verification with the existence of magnetic field. It has been used for all patients treated on Froedtert MR Linac since the first patient was treated on the unit.
3. FastTBI. It calculates treatment MUs quickly, and simultaneously generates the treatment fields, with block code and MLC leaf positions put in if necessary, to be imported into the record and verify system (Mosaiq) for total body irradiation (TBI) treatment. It saves at least 3-5 minutes of procedure time, or even more if MLC leaves are used, for each patient. FastTBI is currently used for all TBI patients at Froedtert hospital.
4. Orthovoltage. It calculates the treatment time and exports the necessary information into the record and verify system (Mosaiq). It has been used for treating superficial cancer patients with the Orthovoltage unit at Froedtert hospital. On average, it reduces treatment preparation time by 2-3 minutes for each patient.
5. FasTSI. It calculates monitor units (MU) and creates beam parameters automatically for 12 electron fields and setup notes for treating total skin irradiation (TSI) patients at Froedtert hospital. It works much more efficiently and reliably compared to the usual manual method.
6. ROInitialSim. It creates patient setup information at CT simulation in a standard format to be transferred for treatment plan generation. It has been used at Froedtert health network.
