The Proton Therapy Dosimetry Head is an anthropomorphic head phantom designed for commissioning and treatment planning system (TPS) verification with any conformal or IMRT Proton Therapy system.

For Commissioning and Treatment Planning

The Proton Therapy Dosimetry Head is constructed of tissue-equivalent materials, which mimic reference tissues within 1.5% for protons and within 1% for photons from 50 KeV to 15 MeV. The Proton Therapy Head can be used during all standard IMRT procedures from CT image acquisition to proton beam delivery verification.

Tissue Equivalent Technology

Tissue equivalency of detailed internal structures makes the phantom ideal for treatment plan evaluation in high density-gradient locations, which are specifically important in proton therapy, such as air cavity vs. bone structures. Internal structures include brain, bone with cortical and trabecular distinction, larynx, trachea, fully-open sinus cavities, nasal and mouth cavities, and teeth with distinct dentine, enamel and root structure.

The Proton Therapy Dosimetry Head approximates the average male human head in both size and structure to allow for intuitive set up with any patient positioning or fixation device.
