2D-aRRaY Seven29

Features

• 27 x 27 (729) vented cubic ionization chambers regularly arranged to MLC leafs across the complete field size of 27 cm x 27 cm
• Avoids detector ageing effects by utilizing ion chambers
• No radiation damage thanks to separated evaluation electronics
• 5 year warranty
• Complete field coverage with Merge seven29

The 2D-ARRAY seven29 is a new concept of an ion chamber matrix in a plane for IMRT verification and quality control in radiation therapy. Utilizing ion chambers avoids radiation defects, the major drawback of solid-state detectors. The vented plane-parallel ion chambers are 5 mm x 5 mm x 5 mm in size, and the center-to-center spacing is 10 mm. In total there are located 729 chambers in a matrix of 27 x 27, providing a maximum field size of 27 cm x 27 cm. The array is only 22 mm flat and 3.2 kg light. The surrounding material is acrylic (PMMA). Due to the square chamber technology the array can be moved 5 mm to close the gaps between chambers. By shifting the array 3 times the whole area is covered. The number of measuring points can be increased to 2916. The 2D-ARRAY seven29 can be used in a flat phantom or in the octagonal phantom OCTAVIUS. With OCTAVIUS the 2D-ARRAY seven29 is suitable for IMAT and Tomotherapy. The 2D-ARRAY seven29 can be used for IMRT plan verification, LINAC QC and online LINAC adjustment. Using the SC Gantry Mount the array can be mounted to the gantry and irradiated under various gantry angles. For patient plan verification in proton and heavy ion therapy a special design 2D-ARRAY xdr is available. This version processes the high dose-per-pulse values in proton and heavy ion therapy. It is compatible with the PTW software.
