Spatial 3D images created by high-definition computational holography are actually demonstrated. The demonstrated 3D images are static images at this stage. However, these presage the great future of 3D displays beyond the Super Hi-Vision because of its strong sensation of depth, which never has been caused by conventional 3D systems.
Micelle gel is a radiochromic hydrogel with the potential to be used as a three dimensional (3D) radiation dosimeter. Since an ideal dosimeter should present water equivalent properties, in this study the water equivalence of two formulations of micelle gel has been investigated by calculating electron density, effective atomic number, fractional interaction probabilities, mass attenuation coef...
BACKGROUND The physician's hands are close to the X-ray field in C-arm fluoroscopy-guided pain interventions. We prospectively investigated the radiation attenuation of Proguard RR-2 gloves. METHODS In 100 cases, the effective doses (EDs) of two dosimeters without a radiation-reducing glove were collected. EDs from the two dosimeters-one dosimeter wrapped with a glove and the other dosimeter ...
This work illustrates a procedure to assess the overall accuracy associated with Gamma Knife treatment planning using plugging. The main role of source plugging or blocking is to create dose falloff in the junction between a target and a critical structure. We report the use of MAGAT gel dosimeter for verification of an experimental treatment plan based on plugging. The polymer gel contained in...
The oxidation of Cr(III) at naturally-occurring concentration levels, i.e., µg dm(-3) or lower levels, by free chlorine during the chlorination process of tap water was studied using an improved solid-phase spectrophotometric method, which can be directly applicable to the specific determination of Cr(VI) at µg dm(-3) or lower levels. The effect of the pH on the oxidation kinetics was investiga...
