摘要：本教程介绍了计算机断层扫描（CT）成像系统如何生成人体内部结构的3-D图像。高端螺旋CT技术的解释，是从光电二极管收集的光被加工成电信号并最终转化为数字格式由数字采集系统（DAS）的方法。这个转换过程中，必须迅速地发生​​，这使得ADC采样速度和分辨率的CT设计的关键。Maxim>Designsupport>Appnotes>A/DandD/AConversion/SamplingCircuits>APP4682Maxim>Designsupport>Appnotes>AmplifierandComparatorCircuits>APP4682Maxim>Designsupport>Appnotes>High-SpeedSignalProcessing>APP4682Keywords:computedtomography,ct,medicalimage,medicalcomponents,catscan,catscan,ctscanMay10,2010APPLICATIONNOTE4682IntroductiontoComputedTomography(CT)MedicalImagingAbstract:Thistutorialexplainshowcomputedtomography(CT)imagingsystemsgenerate3-Dimagesofinternalbodystructures.Thehigh-endspiralCTtechniqueisexplained,asisthemethodbywhichlightcollectedfromphotodiodesisproc……

摘要：本教程介绍如何正电子发射断层显像（PET）成像系统产生的3-D医疗图像。文章详细介绍了如何PET系统检测伽玛射线产生的掺糖注射时不同的反应，受影响的组织。本文还讨论了如何竞争环境中的电气噪声影响成像，以及为什么它是重要的，准确地检测出光子的时间和运动，因此在患者中产生的信号可以本地化。通常在PET系统功能框图显示的IC元件。Maxim>Designsupport>Appnotes>A/DandD/AConversion/SamplingCircuits>APP4680Maxim>Designsupport>Appnotes>AmplifierandComparatorCircuits>APP4680Keywords:PET,positronemissiontomography,medicalimaging,medicalscan,3-Dmedical,gammarays,photon,electricalcomponentsformedicalMay10,2010APPLICATIONNOTE4680IntroductiontoPositronEmissionTomography(PET)ImagingAbstract:Thistutorialexplainshowpositronemissiontomography(PET)imagingsystemsgenerate3-Dmedicalimages.ThearticledetailshowthePETsystemdetectsgamma-raysproducedwheninjecteddopedsugarsreactdifferentlytoaffectedtissue.Thearticlealsodiscus……
