Information processing in scintigraphy
Information processing in scintigraphy
AbstractAbstract
[en] The advent of sophisticated computerized data acquisition systems in nuclear medicine has provided a voluminous amount of dynamic scintigraphic data. The problem at hand is the interpretation of these data into meaningful diagnostic information. It is pointed out that there are a number of difficulties one normally encounters in this endeavor and how we and others have chosen to cope with these problems is indicated. We have suggested: the use of multiple views of a radionuclide distribution for improved accuracy of quantitation, the use of simulation modelling analysis for complicated systems, the arbitrary selection of symmetric regions of interest when no a priori reason to select a particular region is available, and the use of potentially powerful statistical tests such as the analysis of variance or factor analysis to detect anomalous regions when on adequate model is available

AbstractAbstract
[en] A series of methods exists to reconstruct section scan data, being either iterative, using a filter, or by using a two-dimensional Fourier transform. It appears that, provided the system has been correctly set up with appropriate sampling intervals and reasonable signal-to-noise, any of these techniques will give good images. The clinical results so far seem to indicate that such a technique as section scanning can be of some value in refining the diagnosis that may be obtained from conventional brain scanning, which it does not in any way replace. Particular help has been obtained when dealing with lesions of the posterior fossa

AbstractAbstract
[en] In some instances, reconstruction radionuclide tomography must be carried out from projections that do not include projection values for all portions of the object to be reconstructed. This may occur, for example, when the field of view of the detector is limited, or when an opaque foreign body is present within the object. The effects of such incomplete projections upon reconstructions of computer-simulated phantoms were studied, using iterative and convolution methods. Several methods for reducing the resulting artifacts and inaccuracies are discussed

AbstractAbstract
[en] The basic functions of a CT unit are as follows: (1) scanning the patient from various directions with X-ray beams and collecting the projection data, (2) reconstruction of the cross section image, and (3) displaying the image on the monitor. Various units are necessary to perform these three fundamental functions of the CT scanner
