Use of calculations to validate beam quality and relative dose measurements for a kilovoltage X-ray therapy unit
Autor: B J, Healy, R F, Hill
Publikováno v: Physical and engineering sciences in medicine. 45(2)
Relative dosimetry measurements are required to fully commission kilovoltage X-ray units for superficial and orthovoltage X-ray therapy. Validation of these relative dosimetry measurements with Monte Carlo methods is advantageous being independent of

Developing new adaptive secondary electronics for the MAPS project
Autor: Phil Hinz, Oscar M. Montoya, Keith Powell, E. Downey, R. F. Hill, John Ford
Publikováno v: Adaptive Optics Systems VI.
The MMT adaptive secondary mirror, as part of the MMT AO system, was the first of its kind when it was deployed in 2002. The 336 element device used voice coil actuation to deform the optical surface at speeds of 500 Hz. The MMT Adaptive optics exoPl

Photon buildup in orthovoltage X-ray beams
Autor: R F, Hill, P J, Keall, W A, Beckham, M D, Perez
Publikováno v: Australasian physicalengineering sciences in medicine. 21(2)
Orthovoltage x-ray beams exhibit the characteristic of depth dose buildup which is not well described in the literature. The principal reason for this phenomenon is the increase in dose deposited due to electrons set in motion by secondary (Compton)

An independent check method of radiotherapy computer plan derived monitor units
Autor: R F, Hill, M D, Perez, W A, Beckham
Publikováno v: Australasian physicalengineering sciences in medicine. 21(2)
With the increasing complexity of radiotherapy computer treatment planning systems (CTPS), verification of the treatments is an important component of a quality assurance program. The radiation dose delivered to a patient is based on treatment machin
