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


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.
