Opis

Progress in Medical Imaging contains a collection of interdisciplinary reviews of subtopics in medical imaging written by internationally known experts. Topics contained in the book include automatic recognition of cells and tissue types in light microscopy, computerized manipulation and assembly of two-dimensional scans of an organ into images of the three-dimensional organ which can be rotated in space, techniques for reducing the image degradation produced by scattering radiation in chest radiography, recent advances in instrumentation, and principles of positron-emission tomography. The final chapters of this book describe the advantages of pseudo-random codes as transmitted signals for ultrasonic flow measurement, imaging, and medium characterization. The primary audience for Progress in Medical Imaging includes engineers, physicists, and students engaged in research, development, or applications of medical imaging.
