Shaping for PET image analysis

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...

Standards for PET image acquisition and quantitative data analysis.

Quantitative (18)F-FDG PET is increasingly being recognized as an important tool for diagnosis, determination of prognosis, and response monitoring in oncology. However, PET quantification with, for example, standardized uptake values (SUVs) is affected by many technical and physiologic factors. As a result, some of the variations in the literature on SUV-based patient outcomes are explained by...

The metabolic centroid method for PET brain image analysis.

The method of centroids is an approach to the analysis of three-dimensional whole-brain positron emission tomography (PET) metabolic images. It utilizes the brain's geometric centroid and metabolic centroid so as to objectively characterize the central tendency of the distribution of metabolic activity in the brain. The method characterizes the three-dimensional PET metabolic image in terms of ...

Shaping Virtual Image

This paper presents a reflection on themes related to the virtual image. In addition, it tries to define a grammar of the digital virtual image, desuming it from other languages such as those related to photography, cinema or video games. After analyzing in detail the set of information and organizational and strategic activities that govern the shaping of the virtual image, the paper outlines ...
