Monte Carlo Calculation Speed

“SciMoCa offers an impressive calculation speed – a full 3D dose calculated by a Monte Carlo dose engine within minutes! In addition, the Plan QA process is automated. Once we sent the final DICOM plan from the TPS, SciMoCa automatically performs the Monte Carlo calculation and analysis of our plans which is very valuable in a busy RT department.“

IBA Dosimetry Radiation Product SciMoCa Accuracy


SciMoCa achieves an accuracy of < 1% and matches the precision of top-tier algorithms such as Varian´s® Acuros® 1) and Accuray´s Precision® 1) 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.

Monte Carlo. Unlimited.

SciMoCa supports all major RT treatment machines:

  • All C-Gantry based conventional Linacs from Elekta™, Siemens®, and Varian®.1)
  • CyberKnife® (cones, Iris, and MLC).1)
  • TomoTherapy® 1)
  • Varian® Halcyon™ / Ethos™ 1)

SciMoCa supports all treatment planning systems that provide DICOM export.

SciMoCa supports a wide range of treatment techniques such as 3D, IMRT, VMAT, SBRT, SRS, and CyberKnife® treatments.

Calculation Speed: Monte Carlo calculations & results in < 2 min*

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

*SciMoCa Monte Carlo calculation is typically performed in < 2 minutes and can vary depending on several factors.

IBA Dosimetry Radiation Product SciMoCa Workflow

Automated Workflow — Application Simplicity — Quality Outcome


    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.

    SciMoCa provides automatic evaluation of dose calculation results based on customizable protocols and plan 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.

    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.

    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.

NEW: Monte Carlo Patient QA Accuracy now for Varian® Halcyon™ 1)

SciMoCa Monte Carlo patient QA now enables fast and efficient Quality Assurance accuracy for the Varian® Halcyon™ therapy systems. See a typical SciMoCa Patient Report for Halcyon™ 1):

Monte Carlo Accuracy with High Pass Rates

“SciMoCa’s Monte Carlo accuracy allows us to use very tight plan evaluation criteria of 2%/1mm Gamma. Nonetheless, we still see consistently high pass rates of >95%. Based on our clinical experience with more than 150 patient plans, SciMoCa offers the specificity and sensitivity to capture the real errors.”
