introduction: scatter radiation is one of the major sources of error in nuclear medicine data processing. different methods of scatter correction have been introduced in order to improve the quality of data. however the best method is to avoid recording of scatter photons in acquisition. the only difference between scattered and non-scattered photons is the energy. pulse height analyzer is the ...

Biological microparticles, including bacteria, scatter light in all directions when illuminated. The complex scatter pattern is dependent on particle size, shape, refraction index, density, and morphology. Commercial flow cytometers allow measurement of scattered light intensity at forward and perpendicular (side) angles (2 degrees <or= theta(1) <or= 20 degrees and 70 degrees <or= theta(2) <or=...

PURPOSE The proliferation of cone-beam CT (CBCT) has created interest in performance optimization, with x-ray scatter identified among the main limitations to image quality. CBCT often contends with elevated scatter, but the wide variety of imaging geometry in different CBCT configurations suggests that not all configurations are affected to the same extent. Graphics processing unit (GPU) accel...

Multiple research directions in the past have emphasized the beneets of multidesti-nation message passing to support eecient non-personalized communication like broadcast and multicast. In this paper, we investigate whether personalized communications like scatter can beneet by using multidestination message-passing support, if available in a system. In order to use such support, we propose a n...

A Monte Carlo simulation, based on GEANT4, has been developed to compute the contribution of first-order, second-order, and higher order scattering in a Computed Tomography (CT) system equipped with an industrial 450 kV X-ray tube and an area detector. The validation of simulation against the experimental data showed a good agreement. The amount of scattering produced by several hollow aluminum...

Antibodies that bind to human platelet membrane glycoproteins llb and lIla were used to develop methods for analyzing platelet membrane components by flow cytometry. Platelets were tentatively identified by their lowintensity light scatter profiles in whole blood or plateletrich plasma preparations. Identification of this cell population as platelets was verified by using plateletspecific antib...

Charts are an excellent way to convey patterns and trends in data, but they do not facilitate further modeling of the data or close inspection of individual data points. We present a fully automated system for extracting the numerical values of data points from images of scatter plots. We use deep learning techniques to identify the key components of the chart, and optical character recognition...

In this review, I will present an overview of the development of the field of scatter hoarding studies. Scatter hoarding is a conspicuous behaviour and it has been observed by humans for a long time. Apart from an exceptional experimental study already published in 1720, it started with observational field studies of scatter hoarding birds in the 1940s. Driven by a general interest in birds, se...

The second Radio Aurora Explorer satellite, RAX-2, is a triple CubeSat studying the formation of plasma irregularities in Earth’s ionosphere. The spacecraft was developed jointly by SRI International and the University of Michigan, and it is the first satellite funded by the National Science Foundation. RAX-2 launched October 28, 2011 and is currently operating on orbit. RAX uses a bistatic rad...

The ocean depths provide an ever changing and complex imaging environment. As scientists and researches strive to document and study more remote and optically challenging areas, specifically scatter-limited environments. There is a requirement for new illumination systems that improve both image quality and increase imaging distance. One of the most constraining optical properties to underwater...
