3x Faster Commissioning of Your Particle Therapy Rooms
Unique multi-layer ion chamber device with OmniPro-Incline software and a high-sensitivity multi-channel electrometer using ASICs technology. It enables the fastest, most accurate, and reliable depth dose distribution measurements for particles.
Water equivalent material for equivalent scattering properties.
Measure ranges with an accuracy of 0.5 mm compared to measurements in water through the Bortfeld fit.
Small 2.5 cm diameter electrodes
Save up to three hours compared to a single SOBP reconstruction using a water tank (for scanned beams). Acquire monolayers and dose cubes with a single irradiation.
QA routine made simple through state-of-the-art technology
A high spatial resolution system
With a stack of 180 independent vented plane parallel ionization chambers, a native resolution of 2 mm and a circular shaped collecting electrode which presents a diameter of 2.5 cm, the measurement of both Bragg peak (BP) and Spread-Out Bragg peak (SOBP) becomes possible over the full clinical range within the sub millimeter accuracy.
A dedicated multi-channel electrometer
The Zebra is used in combination with a dedicated multi-channels electrometer. The electrometer system is based on the ASICs technology designed to measure with acquisition period down to 10 ms without losing any data. The readout of the 180 chambers of Zebra is performed simultaneously; this unique feature offers a tremendous advantage for the measurement of scanned beams.
Fast user uniformity calibration
The Zebra comes from factory with a complete uniformity calibration. The design has been made with the state-of-the-art technology as for MatriXX (Pixel Ionization Chamber Technology) and ensures highest stability. However, the application offers the possibility of fast recalibration in uniformity on the customer site using methods based either on Proton or Photon radiations.
Comprehensive analysis workspace
The analysis module of OmniPro-Incline provides all the necessary tools to properly and rapidly measure the fundamental Dosimetry parameters like the range or the modulation of depth dose profiles, Bragg peaks (BP), or Spread-out Bragg peaks (SOBP). Measurements can easily be set up or generated automatically with the intuitive graphical environment. The measured data are visualized in a clear, informative way to allow fast and precise analysis.
A water equivalent device
Thanks to the experience acquired with the PIC (Pixel Chamber) technology, the Zebra detector is designed with the appropriated materials in order to assemble a water equivalent device. The thickness of each electrode has been chosen to be approx. 1 mm for a 2 g/cm³ density coupled with an air gap separating each electrode fixed to 1 mm. The resulting consequence of such a design is a geometrical length of the device analogous to its water equivalent one.
Everything you need to see in your Bragg peak
OmniPro-Incline is the advanced software platform for fast and accurate quality assurance in Particle Therapy. It incorporates the latest software technology with an intuitive graphical environment, allowing for easy set-up or automatic generation of measurements. The measured data is visualized in a clear, informative way for fast and precise analysis.
