WebThe gray (symbol: Gy) is the unit of ionizing radiation dose in the International System of Units (SI), defined as the absorption of one joule of radiation energy per kilogram of matter.. It is used as a unit of the radiation quantity absorbed dose that measures the energy deposited by ionizing radiation in a unit mass of matter being irradiated, and is used for … Radformation is a company dedicated to increasing the efficiency and decreasing the errors made in the radiation oncology cancer treatment planning process. We do this through innovative software that in the click of a button evaluates a plan's dosimetric constraints while verifying correct treatment parameters. See more Biologically effective dose (BED), as coined by the British Journal of Radiology some three decades ago, is an attempt to quantify the biological effect (log cell kill) of radiation dose delivery. The formula for BED was derived … See more Suppose you want to compare hypofractionation vs. conventional fractionation and their respective effects on late (α/β = 3) and early (α/β = 10) responding tissues. The standard fractionation scheme … See more With these limitations in mind, it is still a valuable tool in gauging a treatment’s effective dose delivered. In some cases, a BED might be desired, but in other cases, an alternative fractionation schedule is preferred. To aid in … See more The basic BED formalism isn’t a perfect comparison of a fractionation scheme’s effectiveness.
