receiving a deformed imaging phantom corresponding to the individual; evaluating a plurality of previously completed simulations estimating radiation dose absorption; and upon determining, based on the evaluation, that two or more of the simulations match the received set of parameters and received imaging...
Twitter Google Share on Facebook initial radiation Related to initial radiation:initial nuclear radiation The radiation, essentially neutrons and gamma rays, resulting from a nuclear burst and emitted from the fireball within one minute after burst. See also induced radiation; residual radiation. ...
The equation for equivalent dose is defined in Fig. 1. Ionising radiation that forms part of the electromagnetic spectrum (e.g. X-ray and gamma ray) ionise atoms through the photoelectric absorption and the Compton effect. Both these interactions will eject an electron from an atom; this elec...
Patient table for a radiation therapy system or a radiation diagnosis system A patient table for a medical radiation therapy system or radiation diagnosis system is provided. The patient table includes a flat bearing surface and a surface-specific radiation absorption that is measured per radiated sur...
The chemical form of internal emitters is important because it determines the solubility of the radionuclide. The solubility, in turn, is a key determinant of absorption into the body and translocation within the body. Relatively soluble radionuclides are readily absorbed and translocated to internal ...
the patient support system, rotating the at least one source of radiation relative to the target tissue, which comprises and/or is adjacent to a non-target tissue, so that the center of rotation of the beam of radiation is placed at one or more desired locations within the target tissue, ...

Saudi university team treats breast can...
Optical thickness is used as a criterion for expressing the amount of radiation intensity absorbed, equal to the absorption coefficient multiplied by the average value of the characteristic length of the object. So if the amount of light thickness was high (greater than three), the Roseland ...
Irradiation: All or part of the body has been exposed toionizing radiation, but there has been no transfer of radioactive material to the patient. Contamination: Radioactive materials are present on the surface of the body, in a wound, and/or have been ingested. ...
In addition, after pathogenic Escherichia coli infection, the host cytoskeleton changes, and the absorption surface of the intestinal epithelial cells decreases, resulting in persistent diarrhea. Therefore, the researchers concluded that abnormal intestinal motility and massive colonization by Gram-negative ...
