Paper Abstract

In continuation of previous papers by the author [4 and 6] it seems to be suitable to discuss more in detail the NMR in connection with the Radon transform and obtain enhanced pictures by using the Haar transform also i.e. the Radon-Haar transform. There exist many methods of the inverse Radon transform but the two, the filtered back projec- tion - FBP [2, 3, and others] and the circular harmonic decomposition Radon transform, as suggested by Cormack and described e.g. by Chapman & Cary [5], by the author [6] and others are the best ones till today. These inverse formulae should be identical, but due to noise and smoothing effects of the transforming and incomplete datasets their numerical pro- perties may be very different and therefore also the results. The principle of the NMR projection will be known to the general reader. In short a magnetic dipole 11 in a field B0 in the vertical z -axis has a torque µ, Bo and the macroscopic moment of magnetization
