Calculation of effective dose

Medical Physics, 2000
The concept of “effective dose” was introduced in 1975 to provide a mechanism for assessing the radiation detriment from partial body irradiations in terms of data derived from whole body irradiations. The effective dose is the mean absorbed dose from a uniform whole‐body irradiation that results in the same total radiation detriment as from the ...

Effect of variable dose rate on biologically effective dose

International Journal of Radiation Biology, 2013
To investigate the effect of variable dose rate on biologically effective dose (BED).By using the linear-quadratic (LQ) model with bi-exponential repair, we analytically determine the time-dependent dose rate [Formula: see text] which minimizes the effective protraction factor (Geff) and BED under the condition of fixed fraction time and dose per ...

A new definition of biological effective dose: The dose distribution effects

Physica Medica, 2015
A new biological effective dose (BED) is proposed in this note. This new BED definition takes into account the fact that dose distribution is non-uniform for tumors in patients' treatments. This new BED can be calculated from the dose distribution within a tumor, making it practical and useful for clinical applications.

Dose Prescription and Dose-Volume Effects in Radiosurgery

Neurosurgery Clinics of North America, 1992
The optimal use of radiosurgery as a treatment technique requires thorough planning, including careful fitting of the high-dose treatment volume to the target volume, and an understanding of the effects of high-dose single-fraction irradiation on both the target volume and the surrounding normal brain.

The influence of dose rate on the dose-effect relationship

Journal of Radiological Protection, 1990
The sparing effect of reduced dose rate on the severity of the cellular radiobiological effect is interpreted in terms of a linear-quadratic dose-effect relationship which ascribes the sparing effect to the reduction in the quadratic coefficient as the dose rate is reduced.

Neutron dose effect relationships at low doses

Radiation and Environmental Biophysics, 1988
Stimulated by recent observations of non-linearity in the dose effect relationship for the transformation of mammalian cells in vitro by fission neutron irradiation and the reverse dose rate effect in this system, the data for mutation induction in the stamen hairs of Tradescantia occidentalis has been re-examined.
