Statistics of Medical Imaging

Statistical investigation into technology not only provides a better understanding of the intrinsic features of the technology (analysis), but also leads to an improved design of the technology (synthesis). Physical principles and mathematical procedures of medical imaging technologies have been extensively studied during past decades. However, less work has been done on the statistical aspects of these techniques. Statistics of Medical Imaging fills this gap and provides a theoretical framework for statistical investigation into medical imaging technologies. FeaturesDescribes physical principles and mathematical procedures of two medical imaging techniques: X-ray CT and MRIPresents statistical properties of imaging data (measurements) at each stage in the imaging processes of X-ray CT and MRIDemonstrates image reconstruction as a transform from a set of random variables (imaging data) to another set of random variables (image data)Presents statistical properties of image data (pixel intensities) at three levels: a single pixel, any two pixels, and a group of pixels (a region)Provides two stochastic models for X-ray CT and MR image in terms of their statistics and two model-based statistical image analysis methodsEvaluates statistical image analysis methods in terms of their detection, estimation, and classification performancesIndicates that X-ray CT, MRI, PET and SPECT belong to a category of imaging: the non-diffraction computed tomographyRather than offering detailed descriptions of statistics of basic imaging protocols of X-ray CT and MRI, this book provides a method to conduct similar statistical investigations into more complicated imaging protocols.
