1 IMRT QA Points selected. Plan verified. Secondary Check Software for Independent Patient Plan Verification

2 Points selected. Plan verified. Time saved. DIAMOND is a clinically proven secondary check software that allows independent point dose verification calculations for a wide range of treatment plans. It computes the dose at one or multiple dose points and compares the results with calculations from the treatment planning system (TPS), making routine treatment plan QA much faster and simpler. As an independent, software-based verification tool, it can complete and replace QA measurements for treatment plans with PTW OCTAVIUS systems in clinical routine cases. DIAMOND utilizes a modified Clarkson integration and advanced optimization algorithms to ensure the most accurate calculations for dynamic IMRT delivery techniques. ROI-related density tables can be user defined to allow density correction. Calculate IMRT fluence and dose maps and export them to your TPS or VeriSoft patient plan verification software for comparison and detailed analysis. Key Facts Independent patient plan verification fast and efficient, no LINAC time required Dose comparison at one or multiple dose points Multiple treatment techniques supported, e.g., VMAT, IMRT step & shoot/sliding window, conventional 2D/3D techniques, including electron support Advanced ROI option for density correction DTA analysis Fluence/dose mapping Additional capabilities, e.g., support of wedges, corrections of flash and air in breast treatments FDA approved, CE certified DIAMOND a time-saving option for PTW OCTAVIUS systems Dose verification by independent measurements with OCTAVIUS systems for complex plans Dose verification by independent calculation with DIAMOND secondary check software for routine plans 2

4 Optimized Calculation Capabilities DIAMOND performs its calculations based on machine data, modified Clarkson integration and optimized dose calculation algorithms. Modified Clarkson Integration The effective square field size which is equivalent to an irregularly shaped field is accurately determined by a modified Clarkson algorithm. Unique AcuTrack The AcuTrack algorithm is a unique MLC profile model that allows precise tracking of the measured MLC profile (MLC shape) which is particularly important for small field segments. PEV SC Integration The Points-Eye-View Integration is a proprietary head scatter algorithm that projects back into the collimator/mlc system to the flattening filter plane.

5 Additional Calculation Capabilities DIAMOND provides specific tools for detailed plan analysis and optimized calculation. Distance-to-Agreement Define a search radius to calculate additional dose points and find the closest match to the selected calculation point. The DTA tool is particularly helpful for calculations when the calculation point is in a high dose gradient. VMAT & ROI Improve the accuracy of VMAT calculations and simplify IMRT calculations with the new VMAT & ROI option. VMAT & ROI for DIAMOND allows you to import regions of interest (ROIs) and automatically calculate the effective depth for all imported calculation points at any gantry angle by taking tissue densities into account. A user-defined look-up table makes it easy to import ROIs quickly with predefined densities. Use the unique 2D fill mode to display selected densities of the imported ROIs as grayscale values or move the mouse over the ROIs to view them in color for a better analysis. The beam absorption of the treatment table and positioning aids are automatically accounted for by DIAMOND, providing even more accurate calculation results. Fluence and Dose Mapping Calculate IMRT fluence and dose maps and export them to VeriSoft patient plan verification software for a detailed comparison with TPS dose or fluence maps. 5
