Digitized Video Subject Positioning and Surveillance System for PET
Head motion is a significant contribution to the degradation of image quality of Positron Emission Tomography (PET) studies. Images fromdifferent studies must also be realigned digitally to be correlated when the subject position has changed. These constraints could be eliminated if the subject's head position could be monitored accurately. We have developed a video camera-based surveillance sy...
متن کامل4D PET: Beyond conventional dynamic PET imaging
In this paper, we review novel techniques in the emerging field of spatiotemporal 4D PET imaging. We will discuss existing limitations in conventional dynamic PET imaging which involves independent reconstruction of dynamic PET datasets. Various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that util...
متن کاملPET Radiopharmaceuticals
PET (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body. Positrons (ß+) are positively charged beta particles. They are emitted when the atom is proton rich. A positron has only a transient existence. After losing all of its kinetic ene...

متن کاملFrom Subject to Non-Subject: Semiotic Analysis of the Process of Subject Collapse in Contemporary Iranian Realist Paintings in the Last Two Decades
Following the political and social developments in Iran in the mid-1370s, young artists created critical works in the new social and cultural demands. In such an area, the subject of the works moved towards more realism, and social realist painting was re-formed in Iranian contemporary art. These paintings show that the human subject has been indoctrinated with the opinion and rethinking of soc...
