Water equivalence of a solid phantom material for radiation dosimetry applications.

Radiological water equivalence of solid phantoms used for radiotherapy is often desired, but is non-trivial to achieve across the range of therapeutic energies. This study evaluated the water equivalence of a new solid phantom material in beam qualities relevant to radiotherapy applications. In-phantom measured depth distributions were compared to that in water to assess the relative attenuation and scatter characteristics of the material.

Experimental verification of dose enhancement effects in a lung phantom from inline magnetic fields.

Background And Purpose: To present experimental evidence of lung dose enhancement effects caused by strong inline magnetic fields.

Materials And Methods: A permanent magnet device was utilised to generate 0.95T-1.
