IMRT treatment plans were generated using the Philips Pinnacle treatment planning system and delivered to a phantom containing 55 thermoluminescent dosimeter (TLD) locations within the lung and bone and near the lung and bone interfaces with solid water. The TLD readings were compared with the dose...

The process of IMRT requires setting a few basic parameters such as the number of beams and the starting beam locations. The physician defines the target regions and the sensitive regions nearby, along with limits and goals for the doses of each region. The dosimetrist then adjusts the star...

With the advancement of treatment modalities in radiation therapy for cancer patients, outcomes have improved, but at the cost of increased treatment plan complexity and planning time. The accurate prediction of dose distributions would alleviate this is
in Japan. Thus, we must conduct actual measurements beyond LEO to determine effective materials, effective locations, and appropriate thicknesses or combinations on the basis of benchmark evaluations. This information will be useful for interplanetary space flight and travel expected in the near future...
For example, this may be required for determining the radiation dose received by a patient undergoing radiation therapy. The flux integrated over a period of time is called integrated flux or fluence. Mathematically, it is given by (11.2.10)Φ=dNda, where dN represents the number of particles...
The locations of the highest level of FDG accumulation after 40 Gy in local recurrent regions were almost the same as those before radiation therapy in the 12 patients, but maximal SUV decreased significantly from 6.84 ± 3.25 before radiation therapy to 5.14 ± 2.81 at 40 Gy (p = 0.035, ...
In order to be certified, nurses need at least 1,600 hours of experience in infusion therapy within the past two years. Experience can be in any of several areas and doesn’t have to be bedside experience. Nurses must also provide a current, unrestricted Registered Nurse license. ...
1. A method for operating radio-therapy equipment comprising a radio-therapy control system, having a central processing system and memory, to control radiotherapy treatment room equipment, including at least one piece of radio-therapy equipment selected from patient positioning equipment, proton beam ...
