2D projections of the real 3D space are the only available information in the imaging technics like in XRay and MRI. In this paper we study projections of images as generated by Radon transformation. We implemented an image reconstruction algorithm which receives different projections of the original image as input. We performed this experiment using artificially created image in order to test ...

STUDY DESIGN Anthropomorphic phantoms were used to measure radiation exposure to the surgeon phantom's eye. Groups analyzed were: Group 1-no glasses (None); Group 2-leaded lenses without lead sides (WOLS); Group 3-leaded lenses with lead sides (WLS); and Group 4-sport wraparound leaded glasses (Sport). Glasses were 0.75 mm lead equivalent. OBJECTIVE To evaluate the efficacy of three types of ...

In this work numerical simulation and measurements of three-dimensional radiation patterns of a mobile handset model in the presence of a human head phantom were performed at 1800 MHz. Based on theoretical and experimental results, the influence of the human head on the radiation efficiency of the handset has been investigated as a function of the handset size and the distance between the head ...

BACKGROUND Recently, pilot studies from our laboratory have shown that dental surfaces may be discriminated by the analysis of tip oscillations of an ultrasonic instrument, which possesses computerized calculus-detection features. For the evaluation of this smart detection system, its surface recognition qualities are of crucial importance. For in vivo studies, however, it proved to be difficul...

this paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. in fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. thepower output of each hydro unit varies with the rate of water discha...
