    We give an overview of “cardiac electrical imaging”, which is a generalization of the ECG in which more information is acquired by using a larger array of electrodes to record a sequence of “electrical images”. These image sequences can be measured noninvasively on the body surface or invasively on or in the heart muscle itself. Here we briefly discuss the motivation for cardiac electrical imaging, we describe some relevant background electrophysiology to indicate how cardiac electrical imaging can provide information about the heart' s health, and then we give an overview of the technical challenges that arise in displaying, representing, and analyzing these image sequences View full abstract»

    The Society and the IEEE have begun publishing IEEE Signal Processing Letters in both electronic and hardcopy forms. This project is experimental for several reasons, with one reason being that no one knows what forms electronic publication will take. Some of the participating Societies are publishing CD-ROM versions of their transactions, but the purpose of the experiment is to try online electronic publishing. The electronic version of SP Letters mimics the printed version, and contains all the equations and graphics found in every article. Dubbed E-SP Letters, it is available to all Signal Processing Society members via the Web View full abstract»

    Signal processing lies at the core of MRI. Data acquisition and manipulation occur naturally in the spatial Fourier transform domain of the image. A review of the imaging process and the associated image characteristics reveals the many opportunities for contributions from the signal processing community. This article develops the Fourier representation of the imaging process from an overview of the physics of the MRI signal. This article also discusses tradeoffs in acquisition time, resolution, and field of view as well as image degradation associated with noise and motion artifacts. In addition, the ability to manipulate soft tissue contrast over a wide range of independent parameters in MRI is outlined View full abstract»

    As uses for ultrasound increase, so does the need for effective signal processing techniques. In this article we provide an overview of signal acquisition and processing in modern medical ultrasound imaging equipment and present some of the more important concepts in practice today. Images and data types typical of current ultrasound equipment are reviewed; fundamental acoustics and design parameters that affect signal quality and processing strategies are discussed; and current research directions are presented View full abstract»

    We review positron-emission tomography (PET), which has inherent advantages that avoid the shortcomings of other nuclear medicine imaging methods. PET image reconstruction methods with origins in signal and image processing are discussed, including the potential problems of these methods. A summary of statistical image reconstruction methods, which can yield improved image quality, is also presented View full abstract»
