    Limited angular view planar-integral projection reconstruction for fast multislice imaging in NMR is proposed and its efficacy is studied. Alghough it is known that the planar-integral projection reconstruction (PPR) method has advantages in signal to noise ratio improvement in NMR imaging, necessary data acquisition time is too long to be of practical value. In this paper, a study is undertaken on the variations of the PPR method which would lead to a shorter data acquisition time than the orginal PPR method. Also a new method which provides high quality multislice images through the use of limited angular view data acquisition mode is introduced. Computer simulation results and experimentally obtained images are presented for the demonstration of the potential of the method for clinical applications. View full abstract»

    The development of Nuclear Magnetic Resonance (NMR) imaging has brought together the experimental techniques of NMR spectroscopy and image processing with the consequence that new experimental requirements and apparatus are currently being developed. Examples of these requirements include the large amounts of data which can be generated and the effect on data processing and storage requirements. Also, the increased size of objects under investigation necessitate some major changes in the magnet and r.f. system. A discussion of these specific requirements is presented together with an overview of all components of the NMR imaging system. View full abstract»

    As a first step the concept of coupling impedance (c.i.) is extended to characterize the relationship between cause and effect relevant to distinct points. Then we can exploit a new law that relates the transverse c.i. to the lonitudinal one by means of a second derivative. When cause and effect coincide we get the standard definition of c.i. At a first sight the computation of the coupling impedance for the present model seems a trivial problem. In fact the c.i. is proportional to the Green function of the relevant model, which can be found as an open series, for instance in the treatise of Morse and Feshbach. But the authors themselves warn that this series is poorly convergent and in addition should not be differentiated. We succeeded in closing the series. The problem formally seems to be solved. But this procedure could however turn out to be sterile for numerical purposes, where we obviously need series expansions, unless one finds better alternative expansions. This is the final and possibly the most important step, where a different extremely rapidly convergent expansion is found. The use of this expansion has led to the recognition of a vast number of numerical results that are synthesized in the graphic representations of this work. The longitudinal c.i. is scarsely affected by the ellipticity and excentricity of the beam, so that, unless the beam is far off the central beam position, it behaves as in a circular cross section pipe.
