摘要：CT的基本原理是山投影重建图像，关于重建算法，提出了许多算法，其大致可以分为两大类：一类称为解析法，一类是迭代法。其中在常用的迭代重建算法即代数重建技术[1,2](AlgebraicReconstructionTechnique简称为ART)ART算法中,很多因素影响图像重建的质量和效果，本文进行了一些参数仿真分析，成像效果比较。关键词：图像重建；迭代算法；ART；仿真分析：TN919.8文献标识码：A:1007-9599(2012)02-0000-02AnalysisoftheFacto...

解析AndroidART到底是什么？「附：实测数据」Bychaimingkun[核心提示]本文的重点就是以新版Nexus7来作为样机来介绍和测试一下这个神秘的ART。ART是一个什么东西？盼星星盼月亮，11月1日，谷歌终于发布了代号为KitKat的Android4.4和Nexus5。个人认为Android4.4最大的更新就是针对RAM占用进行了优化并且推出ART来代替Dalvik，其甚至可以在一些仅有512MBRAM的老款手机上流畅运行。它也进一步优化了系统在低配硬件上的运行效果，似...
