Preprocessing of Spect Data as a Precursor for Attenuation Correction,orm some kind of attenuation correction. These systems give qualitatively reasonable images. However, for the purposes of quantitation, the results are far from satisfactory. Specifically, it may be observed that, often, when procedures designed to perform attenuation correct are tested and evaluate过多 发表于 2025-3-28 19:33:45

Art vs. Convolution Algorithms for ECT,on algorithms, especially when implemented with the Fast Fourier Transform (FFT). Some of the early work appeared to indicate, however, that iterative methods have better noise handling capabilities than convolution methods (1). In an excellent overview of the iterative reconstruction algorithms Her纤细 发表于 2025-3-29 05:40:44

Application of Linear Classifiers to the Recognition of the Temporal Behaviour of the Heart,as well as efficient methods of data processing. The emphasis is put on the evaluation of the techniques that undergo the burden of clinical routine, and have to meet the capacity of the digital systems already in place in hospitals.音乐会 发表于 2025-3-29 12:52:21

The Normal Heart: Patterns for Various Functional Images Obtained from Radionuclide Gated Equilibrin conjunction with radionuclide gated equilibrium studies. It has become increasingly apparent that a major difficulty in interpreting these images is the relative lack of detailed description of normal patterns and their variants. Knowledge about the normal pattern is also essential when trying todefinition 发表于 2025-3-29 21:07:33

Data Processing in Nuclear Ventriculography: Assessing Cardiac Function from Noisy Data,ng the heart cycle. Making use of ECG gating, computerized acquisition, processing and display, sequences of scintigrams spanning the entire cardiac cycle are obtained. The resulting data (Fig, 1) typically consist of some 65000 integers, each originating from a counting procedure and therefore subj伪书 发表于 2025-3-30 05:28:58
The Definition of a Single Measure of Regional Wall Motion Abnormality in Scintigraphic Ventriculog the global ejection fraction does not necessarily decrease until a substantial fraction of the myocardium has been damaged, and since global parameters are easily influenced by non-myocardial variables such as after-load, pre-load and heart rate, it seemed that a more precise measure of focal damag
