RadCalc Beta version has been released

RadCalc version 7.0 utilizing an FDA 510(k) cleared Collapsed Cone Convolution Superposition Algorithm has been released for beta testing to members of the beta testing team. This release of RadCalc 3Dcc is the first of three 3D Dose Volume second check QA packages. We anticipate completion of the Beta test by the end of September 2019. An announcement of the final release date will be provided on this website and by email when available for purchase.

RadCalc 7.1 Beta version has been released

*3D Monte Carlo Dose Volume Verification External Beam

This package will utilize a revolutionary Monte Carlo dose calculation engine for photons.  The Beta version has been released and completion of beta testing is expected in early October 2019. Final release is expected before the end of 2019. Please review our news item regarding our collaboration with McGill University Inventors.

RadCalc 3D EPID

On July 12th, 2017 we announced our acquisition of Math Resolution’s Assets including Dosimetry Check. Our plans are to incorporate all of Dosimetry Check’s dose calculation functionality into the current RadCalc fully automated platform. This expanded QA platform will provide all of RadCalc’s core dose verification and 3D Dose Volume functionality while adding support for conventional linac EPID and TomoTherapy® detector based patient Pre-treatment and Exit-Transit dosimetry utilizing a collapsed cone convolution superposition algorithm.

The combined QA Software Package will include the first fully automated Pre-Treatment and 3D In-Vivo Exit dose verification software and provides a complete suite of 3D Dose Volume verification analysis tools. The 3D EPID functions are currently available for sale in the form of Dosimetry Check. Contact our sales department for more information about purchasing Dosimetry Check software from LifeLine Software.

Question: 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.

For a demonstration and a quote, please contact our sales department or click on the Request A Demo Link on our Homepage. Our contact information is provided below. We look forward to serving you soon with RadCalc for Brachytherapy.

Question: Does RadCalc® support Varian RapidArc, Pinnacle's SmartArc, and other VMAT solutions?


Yes, RadCalc supports all VMAT solutions. 

One of the most challenging second check calculations 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 and the treatment planning systems do not provide this.
These second check calculations can now 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 the RadCalc software. Average densities for the various structures can be imported (depending on the planning system), automatically selected from a prepopulated density table, or manually entered.

The ability to import Regions of Interest requires one to purchase the Regions of Interest module. Please contact our sales team for a quote. 

Question: Does RadCalc® support CyberKnife?

Yes, RadCalc supports CyberKnife. 

Question: 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.

Question: Does RadCalc® support Superficial calculations?

Yes.  We added this functionality in RadCalc® version 6.3

Question: Why would I need the Import or Export Module?

Depending upon how automated you would like to have your MU or point dose verification process, RadCalc provides these two optional utilities to further streamline the verification process. For example: The Import module allows the user to import all the necessary parameters from the treatment planning system that would be entered by hand into RadCalc automatically, thus speeding up the process of data entry and eliminating potential human data entry errors.

The Export module allows the user to transfer plan information and MU dose to the Verify and Record system if the user cannot transfer this information from their RTP system, thus reducing re-entry of data parameters and potential data entry errors. Another Export module function is when you are using RadCalc to perform simple calculations such as a whole brain, spine, or electron calculations without using the RTP system. These types of calculations can be transferred directly without hand entry of data. Another potential benefit of the Export module is in cases where you would like to modify the imported plan within RadCalc and then send it on to your V&R system for testing or research purposes. RadCalc currently exports to IMPAC/Mosaiq, LANTIS, Varis, and ARIA systems.

As one of our clients stated, "These utilities have tremendously increased our throughput!"

Question: What is the cost?

First, RadCalc is purchased as a site licensed package. You may have as many machines and energies as you like configured. You may also have as many people accessing the software as you like at one institution either via multiple PC's or a Network setup. Additional charges may apply if you have multiple institutions. This would require the purchase at a discount of another site license or if you have more than two machines, additional setup fees may apply depending on your unique situation. Please ask your sales rep for details on your setup. Second, RadCalc has available five optional add on modules, i.e. Import Module, Export Module, the IMRT Module, 3D Dose Volume Brachytherapy, and the Regions of Interest Module. Additionally, the 3D Dose Volume Brachytherapy Module can be purchased as a stand-alone module or be used along with the other modules.
