First, as every wise doctor knows, even the theoretically right medicine can be disastrous if administered in too strong a dose to a weakened patient.
Offsets in the pointing may be imposed, if necessary, to limit the accumulated dose to a given region of the MCP.
For expressing the collective dose to a population, the person-Sv and person-rem are the units used.
In an effort to further pharmacogenomics the ability to prescribe the right drug at the right dose to a patient based on his or her individual genetic profile genomics is a growing component of clinical trials.
At the moment, pharmacists and doctors are wrangling about the pharmacists' right to know when a prescription is being written for purposes of providing a lethal dose to a dying patient who has requested it.
Object: Radiosurgery utilizes stereotactic principles of localization and multiple cross-fired beams to deliver a large radiation dose to a well-defined target with little or no fractionation.
Dose to a point within the thecal sac that receives the maximum dose (P max)), and doses to 0.1-, 1.0-, and 2.0-cc volumes within the thecal sac were reviewed.
Focal irradiation refers the use of many small beams to deliver highly focus dose to a small target region in a few fractions.
The irradiation creep rate exhibited a linear dependence on applied tensile stress, dose rate, and temperature and no dependence on dose to a total accumulated value of 1.0 dpa.
Typically, irradiation-hardening rates are large, in the range 100 1000 GPa/dpa, at the lowest dose of <0.0001 dpa and decrease with dose to a few tens of MPa/dpa or less at about 10 dpa.
Previously, we have used data from the last 5 solar cycles to estimate percentiles of dose to a typical blood-forming organ (BFO) for a hypothetical astronaut in a nominally shielded spacecraft during a 120-d lunar mission.
