In this work, a reconstruction approach using partial k-space, the “Optimized Discrete Fourier Transform” (ODFT), is introduced. The developed approach decomposes the 2-D Fourier Transform (FT) into two steps of 1-D DFT. The corresponding elements along each row or column are estimated using an optimization technique, namely, the complex conjugate gradient. It is proposed to be implemented in conjunction with other techniques to obtain an optimum image that is closer to the original image. The algorithm is evaluated visually and quantitatively using the Performance Test and the Mean Square Error as similarity measures. Also, its effectiveness is compared with different MRI reconstruction techniques such as the Projection onto Convex Set technique, the Conjugate Synthesis technique and the Zero filling technique. The results illustrate that the proposed technique outperforms the conventional MRI image reconstruction techniques.","PeriodicalId":423880,"journal":{"name":"2015 Signal Processing: Algorithms, Architectures, Arrangements, and Applications (SPA)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133491304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reasons are new and enhanced fault mechanisms that affect either a higher vulnerability against transient faults, caused by particle radiation, or pre-mature aging due to device degradation. More recently, power dissipation on ICs has become a major problem, also affecting reliability aspects, since most fault mechanisms are strongly enhanced by higher temperatures. The final challenge is to handle a variety of fault effects at minimum cost in extra hardware in order to enhance dependability and system life time. The tutorial first gives an introduction into the basic problems. Next methods for the detection and correction of short transient faults are shown. Then methods that can detect and correct delay faults are presented, followed by new architectures that may handle transient faults and delay faults in combination. Built-in self repair (BISR) is presented as a method that is not capable of on-line error correction, but may be helpful for life-time extension. Finally there is a comparison of such technologies in terms of requirements for extra time or extra power.","PeriodicalId":423880,"journal":{"name":"2015 Signal Processing: Algorithms, Architectures, Arrangements, and Applications (SPA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122373708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
