The importance of medical imaging for diagnostics is rapidly increasing. A good working knowledge of all the different possible physical principles involved in medical imaging is now imperative. This book covers many of these principles including matter photon interactions, the principles of detectors, detectors and information processing for radiology, X-ray tomography, positron tomography, single photon tomography and optical tomography.Digital signal and image processing series.Diagnostic imagingDigital techniquesImaging systems in medicineData processingDiagnostic imagingDigital techniques.Imaging systems in medicineData processing.616.0754Fanet HervéMiAaPQMiAaPQMiAaPQBOOK9910813506803321Medical imaging based on magnetic fields and ultrasounds4082922UNINA
