Monolith Arrives on Earth

Dec 12, 2017 - The planets have aligned...

The planets have aligned. Coming to a planet ripe for advancement and new technology, the IC256-45 Monolith quality assurance ionization chamber is large enough at 45 cm by 45 cm sensing area to cover the largest pencil beam scanning field at isocentre. 256 strips in each axis give a 1.75 mm pitch, with typical beam spot position resolution of 0.2 mm or better.

This new detector saves time and removes uncertainty in the process of calibrating and checking the position of beam spots in a pencil beam scanning particle therapy system. With compatible dose delivery systems it can be linked to the scan control system for automated data collection and analysis.

The Monolith is available with a variety or readout options at different price points. It is also available for rental. Call us for more details.

Ion Chambers

The ionization chamber or ion chamber is conceptually the simplest of all gas-filled radiation detectors, and is widely used for the detection and measurement of ionizing radiation. It is the preferred device for proton therapy dose and beam position monitoring due to a combination of robustness, gain stability, very low material budget in the beam path and availability of large continuous sensing areas.

Pyramid offers a wide range of ionization chambers for proton and heavy ion therapy applications. Advanced electrode coating and patterning allows the creation of precise strip and pixel patterns for position readout. A wide range of sensitive areas and electrode gaps is provided to suit different system geometries and beam currents.

Proton Therapy

Proton therapy is well established for the treatment of localized cancer tumors, especially when there are vital organs close by. This healthy tissue sparing makes it the method of choice for maintaining quality of life and especially for treating children. The proton beam delivery is fast and painless.

Proton therapy centers worldwide use Pyramid sensors, electronics, and software. Pyramid offers products for complete systems, sub-systems, or components. For more information see our Pencil Beam Scanning Brochure
