Dose analysis

RadCalc provides vendor independent calculations for unbiased quality assurance in an easy-to-use software platform.
Quality assurance tasks are increasingly demanding. RadCalc satisfies recommendations for an independent check of MU’s and in vivo dosimetry as recommended by “Comprehensive QA for Radiation Oncology”, report of AAPM Radiation Therapy committee Task Group 40.

RadCalc's range of calculations

IMRT Treatment Plans

IMRT Treatment Plans

RadCalc supports Step & Shoot, Sliding Window, Dynamic Arc, VMAT, and Compensator based IMRT calculations with the ability to view MLC and calculate fluence and dose map patterns. For improved accuracy of breast plan calculations, RadCalc allows you to draw the breast outline so that the loss of scatter, due to missing tissue, is taken into account.

Electron & Photon Calculations

Electron & Photon Calculations

Fast calculations can be performed by using the EZ Photon and Electron tools. Photon computations utilizing a Clarkson summation or other methods can be done on MLC and complex block outlines. For electron calculations, a library of custom cutouts can be maintained. Cutout factors can be computed using a sector integration or square root method.

Wedges

Wedges

RadCalc supports most wedge types such as Varian’s Enhanced Dynamic Wedge (EDW), Elekta’s Motorized Wedge, Siemen’s Virtual Wedge (VW) and Hard wedges. Off axis calculations may be performed for all supported wedge types. By utilizing separate PDD data, RadCalc accommodates beam hardening.

3D off Axis Assistance

3D off Axis Assistance

RadCalc's use of 3D coordinates simplifies the process of off axis calculations by automatically computing the off axis distances in the Beams Eye View (BEV). The tool can also be used to manually position the off axis point.

Diodes

Diodes

RadCalc can perform diode calculations for both Photon and Electron beam types by computing an expected reading or range based upon the Dmax dose. Correction factors for Photon beams may include: SSD, field size, attenuator factors, wedge factors, and off axis factors. Cone correction factors may be used for Electron beams.

This tool allows for a more robust and accurate VMAT calculation while also eliminating the need to manually  enter depths and effective depths for conventional photon and IMRT computations.

“RadCalc is accurate, fast and intuitive. Every update includes customer suggestions, as we strive to continuously meet our customers’ needs”

Features

Plan comparison

With this feature users can compare the plan from the R&V system with the plan data directly exported from the TPS, thus discovering errors during the plan export process. Users can also easily analyze two arbitrary plans and see whether the beam parameters are the same in the plans or highlight potential differences.

Fluence and Dose Map analysis

Users can extend the pre-treatment MU verification with comparing RadCalc calculated Dose Map with a measured, or TPS calculated Dose Map and with comparing the RadCalc calculated fluence with TPS fluence or calculated fluence from Linac log file.

Diode and TLD calculations

RadCalc performs in-vivo diode calculations for photon and electron beams by computing an expected reading or range, based on the Dmax dose. Results can be collected through the course of treatment and stored with the secondary dose verification calculations. By transferring the results to the R&V System it can be part of the complete patient documentation.
