It is designed for both therapy and imaging with improved uniformity and durability in mind. Solid Water®HE uses new nano-spheres to create homogeneous slabs while mimicking true water within 0.5% across a wide range of energies.
WebJul 1, 2024 · Solid phantoms are designed for, and routinely used in, megavoltage X-ray beam radiation therapy. These solid phantoms are not necessarily designed to be water-equivalent at low X-ray energies, and therefore may not be suitable for MRT QA. This work quantitatively determines the most appropriate solid phantom to use in dosimetric MRT QA.
