PTW seven29 2D-ARRAY Ion Chamber Matrix
2D-ARRAY
seven29
Detector matrix with 729 ionization chambers for quality control and dosimetry in radiation therapy
Features:
Provides a (27 x 27) ion chamber matrix resulting in an effective measuring field of 27 cm x 27 cm
Can be used in a slab phantom due to the flat design
Records dynamic and static fields in just one run
Displays absorbed dose or dose rate
Avoids detector ageing effects by utilizing ion hambers
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 planeparallel 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 27 x 27, providing a maximum field size of 27 cm x 27 cm. The surrounding material is acrylic (PMMA).
The 2D-ARRAY
seven29
can be used for the dose verification of IMRT beams by using the VeriSoft software, and it can be used for routine quality control of high-energy photon and electron beams by using the MultiCheck software. MLC leaf positioning can also be checked by the 2D-ARRAY
seven29
.
The package includes an interface for fast data acquisition. The display cycle can be set between 400 and 1000 ms and the MatrixScan software acquires dose and dose rate data, displays 3D graphics and transfers the acquired data to VeriSoft, MultiCheck or MEPHYSTO mc2 software.
