March 2017: VMAT Check 9.3.0 released
In this version of the VMAT Check software, we introduce a new distance-to-agreement feature. This feature searches the dose file within a specified radius and tolerance, and determines if a point below the threshold exists in that radius around the initial calculation point. Similar to the existing volume average feature, distance to agreement is fast and can search thousands of points in milliseconds. Excellent when the calculation point is in a high-gradient region.
VMAT Check is one of the newest additions to the MuCheck product suite. This powerful module is packed with many advanced features for second-checking your VMAT, RapidArc, SmartArc, or other arc therapy plans. VMAT Check includes an enhanced algorithm. The software also includes the ability to read CT image files to automatically calculate the SSD, depth, and effective depth for each control point along the arc. Several tools are included, such as the ability to view the movement of the calculation point within the beams-eye view. VMAT Check can be purchased as a stand-alone dose calculator or as an add-on to your existing MuCheck second-check product suite.
VMAT Check Features
VMAT Check features an enhanced calculation algorithm, designed with rotational arc plans in mind.
VMAT Check uses the CT image set to automatically calculate the SSD, depth, and effective depth for each control point in the arc. This results in increased accuracy for your calculation, with no manual input necessary.
Numbers are great, but sometimes pictures can convey data more efficiently. VMAT Check displays a visual representation of the collimator, gantry, and table positions throughout the arc calculation. In addition, the software also visually shows the off-axis point as it appears in the beams-eye view.
VMAT Check offers new off-axis features that not only allows you to set an off-axis point, but also visually shows where (in the beams-eye view) that point is at any point during the treatment. This visual tool comes in handy for letting you know whether the calculation point under a block for part of the treatment.
When doing second-check calculations, it can be tedious to go back to the planning system whenever you need to set a different calculation point. With VMAT Check, you don’t have to! By importing the dose file and the CT image set, VMAT Check has all the information it needs to calculate the SSD, depth, and effective depth information to the new calculation point, as well as compare the calculated dose with that from the treatment planning system.
In addition to displaying the relevant data at the beam level, VMAT Check features a segment analyzer tool that displays many of the calculation parameters at a control point level. The segment analyzer shows the monitor units, dose, SSD, depth, effective depth, and BEV calculation point in a tabular format. Easily export this data to Excel for easy analysis.
Perfect for points in high-gradient regions, the 3D volume average tool calculates 27 points above, below, and around the calculation point at a specified radius. When the volume average is complete, the point with the best agreement is automatically highlighted.
The Distance to Agreement feature searches the dose file within a specified radius and tolerance, and determines if a point below the threshold exists in that radius around the initial calculation point. Similar to the existing volume average feature, distance to agreement is fast and can search thousands of points in milliseconds. Excellent when the calculation point is in a high-gradient region.
