Noise Analysis and Reconstruction of PET Image

This paper will deal mainly with the performance study and analysis statistical properties of the noise found in various PET images. The method is specifically designed for types of noise produced by acquisition and transmission sequence in PET images. Here signal fluctuations generally originate in the physical processes of imaging rather than in the tissue textures. Various types of noise (tr...

Measurement of cytosolic calcium using 19F NMR.

Fluorine-19 nuclear magnetic resonance (NMR) studies of cells and perfused organs loaded with fluorinated ion chelators represent a new approach to determining cytosolic free calcium levels in situ. The molecular basis for this approach and the relative advantages and disadvantages of the NMR technique are discussed in this paper. Results obtained on perfused normoxic and ischemic rat hearts ar...

Regulation of Cytosolic Calcium in Plants.

Cytosolic Ca2+ has been likened to a kind of cellular fire (Rasmussen et al., 1990). The metaphor is apt in an obvious way because it suggests that transient or localized elevations in cytosolic Ca2+-like a fire contained in a hearth-may be useful to plant cells for performing certain tasks, whereas uncontrolled or prolonged elevations in cytosolic Caz+-like a fire loose on the roof-are destruc...

Noise Model Analysis on Image Sensor Arrays

This paper presents a new noise model and its application to Bayer color filter array (CFA). We investigate the effect of various noise models. In addition, we study three possible Bayer patterns. For example, current Bayer CFA utilizes RGGB pattern. However, one may consider other color combinations such as RRGB or RGBB patterns. To prove RGGB pattern’s superiority, we investigate each pattern...

Non-Stationary CT Image Noise Spectrum Analysis

We investigate the spatial dependency of noise characteristics in CT images. The perceived image quality depends on the noisegranularity. Especially in low-dose applications the noise granularity influences the diagnostic value. A model is presented, that provides two-dimensional, stationary noise realizations for arbitrary image pixel locations from which two-dimensional Noise Power Spectrum e...
