Metal artifact reduction strategies for improved attenuation correction in hybrid PET/CT imaging

Metallic implants are known to generate bright and dark streaking artifacts in x-ray computedtomography (CT) images, which in turn propagate to corresponding functional positron emissiontomography (PET) images during the CT-based attenuation correction procedure commonlyused on hybrid clinical PET/CT scanners. Therefore, visual artifacts and overestimation and/orunderestimation of the tracer uptake in regions adjacent to metallic implants are likely to occur andas such, inaccurate quantification ...

Jaein Jeong and Cheng Tien EeDepartment of Electrical Engineering and Computer ScienceUniversity of California, BerkeleyMay 16, 2003 AbstractIn any network, there are two basic methods to recover errorneous packets. One way is to useAutomatic Repeat Request (ARQ), and another is Forward Error Correction (FEC). Since, in sen-sor networks, power is scarce and is primarily consumed by wireless transmission and reception,we would prefer to use FEC rather than ARQ. In this paper we determine empirica ...

دانلود مقاله Error Correction Codes in Wireless Sensor Network: An Energy Aware approach انتشار 2010

World Academy of Science, Engineering and TechnologyVol:4 2010-01-26 Mohammad Rakibul Islam   Abstract—Link reliability and transmitted power are two importantdesign constraints in wireless network design. Error control coding(ECC) is a classic approach used to increase link reliability andto lower the required transmitted power. It provides coding gain,resulting in transmitter energy savings at the cost of added decoderpower consumption. But the choice of ECC is very critical in thec ...
