SciMoCa™ from IBA

Monte Carlo secondary dose check and plan QA.

Overview

What is SciMoCa? How will it improve daily QA work?

SciMoCa establishes a new standard for accuracy in secondary dose check and independent plan QA. SciMoCa is powered by the accuracy of Monte Carlo dose calculations. It identifies TPS dose errors and discrepancies with minimal effort and provides instantaneous feedback regarding treatment plan quality and achievement of planning objectives. SciMoCa utilizes a best-in-class Monte Carlo dose calculation algorithm with an outstanding academic pedigree to assure the quality of your QA. Enhance the quality of your treatment planning and patient QA with the accuracy of Monte Carlo.

Accuracy

SciMoCa achieves an accuracy of < 1% and matches the precision of such top-tier algorithms as Varian´s Acuros® and Accuray´s Precision® Monte Carlo. The Monte Carlo calculation provides dose to medium and dose to water. This accuracy is achieved due to the quality of this Monte Carlo implementation in addition to a custom machine-specific Linac beam model. This model is generated for the customer using proprietary processes and dedicated expert tools, backed by extensive expertise.

Calculation Speed

SciMoCa provides the full overview of whether the treatment plan is within constraints or not. The speed of the Monte Carlo engine for full 3D dose calculations is truly impressive because the algorithm makes optimum use of modern hardware architecture. The outstanding performance is enabled through the fast dose engine, the calculation in the background, and the automation of the workflow.

Automated Workflow — Application Simplicity — Quality Outcome

Automatic process
Treatment plans are simply exported from the TPS via DICOM to the SciMoCa dose calculation server. Then SciMoCa starts the Monte Carlo calculation automatically. The patient worklist is automatically updated to keep the user informed about the current QA status of each patient plan.

 

Automatic analysis
SciMoCa provides an automatic evaluation of dose calculation results based on customizable protocols and plans quality measures for both target volumes and OARs.
This allows users to evaluate plan quality as well as identify dose discrepancies based on user-defined dose-difference thresholds.

 

Comparative DVH
DVHs for the treatment plan as well as the independent SciMoCa dose distribution are compared in the comparative DVH section.
The software allows individual selection of structures for the DVH display, thereby enabling a detailed and focused evaluation of relevant ROIs.

 

3D analysis via slice viewer
SciMoCa includes a slice viewer to visualize the TPS dose, SciMoCa-recalculated Monte Carlo dose, and Gamma analysis on individual CT slices. The 3D viewer permits detecting dose discrepancies on the patient anatomy level.
