This book was released on 2011 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new Magnetic Resonance Imaging (MRI) technique was developed to measure the three-dimensional, time-averaged scalar concentration distributions in turbulent mixing applications. The diagnostic was initially developed and tested in a turbulent free shear layer experiment where it was validated using planar laser induced fluorescence (PLIF) experiments. The remainder of the study examined a three-dimensional mixing flow motivated by trailing edge film cooling of an aircraft gas turbine blade. A modern slotted trailing edge cutback geometry was added in which coolant was discharged from rectangular slots separated by tapered lands. Water, and water with copper sulfate were the working fluids, and the MR-based experiments were conducted at Reynolds numbers based on airfoil chord and bulk velocity from 100,000-250,000. The magnetic resonance concentration (MRC) technique was further refined in the film cooling apparatus to reduce the uncertainty to under 6.0% in concentration and to provide robust measurement of the surface concentration. Combined magnetic resonance velocimetry (MRV) and MRC measurements were acquired for a generic trailing edge cutback geometry. The effect of variations in the blowing ratio and Reynolds number were examined. Reynolds number was found to have no significant effect while the variations in blowing ratio produced relatively small changes. Combined MRV and MRC data sets were analyzed in detail for insight into the mean flow structures primarily responsible for rapid mixing of the mainstream and coolant flows. Longitudinal vortices formed inside the slot feed channels and at the edges of the lands played a critical role as did the separation bubble behind the slot lip. Three modifications to the breakout geometry were designed with the goal of minimizing the adverse effects of these flow structures. Performance improvements with the redesigned trailing edge geometries indicate as much as a 40% improvement in the averaged surface effectiveness using a non-dimensional performance parameter.

Download or read book MRI from Picture to Proton written by Donald W. McRobbie and published by Cambridge University Press. This book was released on 2017-04-13 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: MR is a powerful modality. At its most advanced, it can be used not just to image anatomy and pathology, but to investigate organ function, to probe in vivo chemistry, and even to visualise the brain thinking. However, clinicians, technologists and scientists struggle with the study of the subject. The result is sometimes an obscurity of understanding, or a dilution of scientific truth, resulting in misconceptions. This is why MRI from Picture to Proton has achieved its reputation for practical clarity. MR is introduced as a tool, with coverage starting from the images, equipment and scanning protocols and traced back towards the underlying physics theory. With new content on quantitative MRI, MR safety, multi-band excitation, Dixon imaging, MR elastography and advanced pulse sequences, and with additional supportive materials available on the book's website, this new edition is completely revised and updated to reflect the best use of modern MR technology.
Download or read book Medical Imaging Systems written by Andreas Maier and published by Springer. This book was released on 2018-08-02 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.
Download or read book Magnetic Resonance and Its Applications written by Vladimir I. Chizhik and published by Springer Science & Business Media. This book was released on 2014-04-08 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to the description of the fundamentals in the area of magnetic resonance. The book covers two domains: radiospectroscopy and quantum radioelectronics. Radiospectroscopy comprises nuclear magnetic resonance , electron paramagnetic resonance, nuclear quadrupolar resonance, and some other phenomena. The radiospectroscopic methods are widely used for obtaining the information on internal (nano, micro and macro) structure of objects. Quantum radioelectronics, which was developed on the basis of radiospectroscopic methods, deals with processes in quantum amplifiers, generators and magnetometers. We do not know analogues of the book presented. The book implies a few levels of the general consideration of phenomena, that can be useful for different groups of readers (students, PhD students, scientists from other scientific branches: physics, chemistry, physical chemistry, biochemistry, biology and medicine).

Download or read book Laser Techniques for Fluid Mechanics written by R.J. Adrian and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume includes revised and extended versions of selected papers presented at the Tenth International Symposium on Applications of Laser Techniques to Fluid Mechanics held at the Calouste Gulbenkian Foundation in Lisbon, during the period of July 10 to 13, 2000. The papers describe instrumentation developments for Velocity, Scalar and Multi-Phase Flows and results of measurements of Turbulent Flows, and Combustion and Engines. The papers demonstrate the continuing and healthy interest in the development of understanding of new methodologies and implementation in terms of new instrumentation. The prime objective of the Tenth Symposium was to provide a forum for the presentation of the most advanced research on laser techniques for flow measurements, and communicate significant results to fluid mechanics. The application of laser techniques to scientific and engineering fluid flow research was emphasized, but contributions to the theory and practice of laser methods were also considered where they facilitate new improved fluid mechanic research. Attention was placed on laser-Doppler anemometry, particle sizing and other methods for the measurement of velocity and scalars, such as particle image velocimetry and laser induced fluorescence.
Download or read book The Physics and Mathematics of MRI written by Richard Ansorge and published by Morgan & Claypool Publishers. This book was released on 2016-11-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic Resonance Imaging is a very important clinical imaging tool. It combines different fields of physics and engineering in a uniquely complex way. MRI is also surprisingly versatile, 'pulse sequences' can be designed to yield many different types of contrast. This versatility is unique to MRI. This short book gives both an in depth account of the methods used for the operation and construction of modern MRI systems and also the principles of sequence design and many examples of applications. An important additional feature of this book is the detailed discussion of the mathematical principles used in building optimal MRI systems and for sequence design. The mathematical discussion is very suitable for undergraduates attending medical physics courses. It is also more complete than usually found in alternative books for physical scientists or more clinically orientated works.
