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.

What our customers say

UFPTI Commends MLIC for Speed and Reliability in Proton Therapy Commissioning

"At UFPTI, we were very fortunate to have access to a prototype MLIC* during the commissioning of the uniform scanning treatment mode. We found the device to be extremely stable and easy to use, speeding up the process tremendously. In addition to handling the passive scattering requirements, the MLIC* has the unique ability to perform the commissioning for dynamic beam delivery techniques. We are so confident in the efficiency and reliability of the MLIC* that we plan to establish our future QA procedures around using the MLIC* device from IBA."

Mr. Slopsema (M.S.) Medical Physicist
Essential for Quick and Efficient Proton Center Commissioning

“One important device you really need to have in a Proton Center is a Zebra. It makes your life much easier because it measures a PDD Bragg peak and SOBP much quicker than with a water phantom. The Zebra helps to significantly reduce your commissioning time.”

Dr. Ding, Lead Medical Physicist, Proton Beam Therapy at William Beaumont Health System
