Radiation Therapy Dose Delivery
Acta Oncologica, 2003In an investigation by the Swedish Cancer Society, the present status critical issues and future aspects and potentials in each of nine major areas of radiation therapy research were described by an expert group. The report presented here deals with radiation therapy dose delivery. dose distributions, beam shaping and intensity modulation.

Radiation dose in neuroradiological procedures
Neuroradiology, 1978Radiation dose is cumulative in the radiosensitive organs. In neuroradiology the organ of particular interest is the eye. There is an immutable physical relationship between spatial resolution, signal-to-noise ratio (i.e., density discrimination), and dose: Dose alpha (formula: see text).

This paper considers the influence of phantom geometry on the dose, particularly the maximum dose, within the phantom. It is shown that the maximum dose within an irradiated convex phantom cannnot exceed the maximum dose in a slab similarly irradiated and thus maximum doses computed for slabs supply upper estimates of doses for many phantoms. The first

Webster defines the word “dose” as “the measured quantity of medicine to be taken at one time or in a given period of time; a definite quantity or portion, usually small, of anything regarded as having a remedial or beneficial influence.” “Dosage” is defined as “the administration of medicine in doses, especially in graded doses, according to age, etc.“

The letter of Prof. Samuel (June 1982) brings out a feature that has worried me for some years—the size of the reject rate in a hospital, and therefore a measure of unnecessary radiation. Most departments do not know their own reject rate but will say “it is at most 5%”.
