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...

Before you begin making measurements the microStar should be calibrated to your specific environment. This process, (i.e. creating a calibration curve) is extremely important as it correlates the optical response from a dosimeter to a known dose in order to establish the sensitivity of the system (measured in counts/dose). Fortunately, this is simple to do and the results can be stored for late...

We define a numerical invariant, the differential Swan conductor, for certain differential modules on a rigid analytic annulus over a p-adic field. This gives a definition of a conductor for p-adic Galois representations with finite local monodromy over an equal characteristic discretely valued field, which agrees with the usual Swan conductor when the residue field is perfect. We also establis...

Tempo perception has been studied using many different methodologies in trying to isolate the motion patterns of a conductor in experimental stimuli. In doing so, the context of conducting has been ignored including secondary bodily motion, expression and communication from the conductor, and conducting gestures outside of the realm of tempo control. The aim of this study is to test the ability...

The accurate and fast computation of the per unit length (pul) internal impedance of rectangular conductors is required in electromagnetic analysis of various engineering and scientific problems where high current frequencies are involved [1, 2]. This pul internal impedance of a rectangular conductor can also be used in more complicated conductor structures where the shape of the conductor is a...

The initial temperature of a heat conductor is zero and its boundary temperature is kept equal to one at each time. The conductor contains a stationary isothermic surface, that is, an invariant spatial level surface of the temperature. In a previous paper, we proved that, if the conductor is bounded, then it must be a ball. Here, we prove that the boundary of the conductor is either a hyperplan...
