FAQ

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. 

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. 

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. 

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.

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. 

Yes, RadCalc supports CyberKnife for single point calculations.  

Yes. We added this functionality in RadCalc version 6.3 

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.  

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. 

For the installation and operation of RadCalc 6.4, the following specifications must be followed:
