FAQ
We have compiled a list of frequently asked questions with the corresponding answers for you. For further questions please contact our technical support.
General
How does automation work with 2D vs. 3D calculations using RadCalc AIR (Automated Import and Reporting)?
2D point dose calculations will always be triggered by RadCalc AIR. If CT images, ROI structures and 3D dose information is also available with the plan, 3D calculations will be performed as well. If both Monte Carlo and Collapsed Cone algorithms are available for 3D dose calculations, the default calculation type can be selected in the Institution Setup menu within RadCalc.
Can I use RadCalc remotely, from my home office?
Yes, RadCalc can be used remotely with many simultenous users, at no extra cost. The details of settings can be found in the User Manual Chapter 1.1, or you can contact our service depatrment for further assistance.
What about RadCalc 3D EPID Dosimetry?
With the end of support for Dosimetry Check, we have incorporated all of Dosimetry Check’s 3D EPID dose calculation functionality into RadCalc. This expanded QA platform will provide all RadCalc’s core dose verification and 3D dose volume functionality while adding support for conventional linac EPID-based patient pre-treatment and exit-transit dosimetry using a collapsed cone convolution superposition algorithm. This makes RadCalc to a single platform for all patient QA needs.
Does RadCalc support VMAT solutions of other vendors like Varian RapidArc, Pinnacle's SmartArc, and others?
Yes, RadCalc supports all VMAT solutions. One of the most challenging second check calculation in radiation therapy is the Volumetric Modulated Arc Therapy (VMAT) calculation, with trade names such as RapidArc, Monaco with VMAT by Elekta, and SmartArc. The challenge has to do with the fact that the treatment planning systems only provide a physical average depth and effective depth. This is not adequate because the beam does not have a constant output as it rotates around the patient. A correct solution requires that the depth and effective depth for every control point be known.
These second check calculations can be performed quickly, easily, and effectively with RadCalc's Regions of Interest (ROI) Module. A Regions of Interest tab was added to RadCalc's Photon Calculations for this purpose. To perform these calculations, the CT structures are exported along with the plan file from the VMAT calculation to RadCalc. Average densities for the various structures can be imported (depending on the planning system), automatically selected from a prepopulated density table, or manually entered.
How can I send DICOM plans to RadCalc?
RadCalc can import DICOM files stored in the filesystem, but RadCalc also provide a service to receive DICOM information over the network. The configuration of this service (AE title, output directory, port number) is described in details in the Technical Reference 7 document.
Subscription and support
How can I reduce the upfront spending?
We understand the need of our customers for reduced spending. We therefore offer subscription packages* on an annual or multi-year basis. Subscription packages make spending more manageable and transparent over time. As delivery techniques and routines change, users can match the spending to meet their actual needs. Latest updates and new features are included as well as technical support and maintenance. Lower initial spending helps increase accessibility, especially during challenging budgetary times.
Users can select from four pre-configured packages Essential, 3D Premium, 3D Gold, and 3D Unlimited and add additional modules to meet their specific clinical needs.
More information can be found on here.
*Subscription packages available within the US and Canada
What payment options do I have?
We accept payment via check, wire transfer, or credit card.

Supported modalities
Does RadCalc support Brachytherapy?
Yes. It supports 3D dose volume Brachytherapy calculations which include DVH protocols. The Brachytherapy module is available for purchase to those clients who have upgraded to or purchased RadCalc version 6.0. The Brachytherapy module will function only with version 6.0 and future releases.
Does RadCalc support CyberKnife?
Yes, RadCalc supports CyberKnife for single point calculations.
Does RadCalc support Superficial calculations?
Yes. We added this functionality in RadCalc version 6.3
Hardware and other requirements
For 3D dose volume calculations, do I need special computer hardware?
We recommend two types of dose engine computers to perform 3D Collapsed Cone and Monte Carlo calculations. Please request the specifications for a GPU and CPU dose engine computer from our sales team. These are not sold by us but can be bought from specialized retailers.
What are the physics data input requirements for RadCalc?
We have an automated process to configure your system to make this a very easy process. The following input would be needed: TMR, TPR, or PDD data Output factors: Total scatter or phantom and collimator scatter factors Wedge factors: Single factor or field size dependent factors Attenuator Factors: For block trays and other devices Off Axis Profiles: For open and wedge fields of varying field sizes and depths Electron cone and cutout factors.
