- Chapter 7 introduced the usual interference in the data acquisition system , including same intrinsic noise interference of the devices , some common impedance interference electromagnetism interference and discussed the method to restrain them
在第7章，介绍了数据采集系统常见的干扰，包括器件固有噪声干扰、公共阻抗干扰、电磁场干扰、并讨论了抑制这些干扰的措施。 - Wlththe fleetingprogress ofcomputerteccioanddlgltaltechology ， newly devefoped duntlzed medicine techniques go on expending ， while computed radlographyls atyplcalmethods itheprocedure ofcomputedradlographylmaging ， we should irstlygetacross the characters ofklnds ofnolses andthe relationship betweenthe image signals andnolses basedonthe specialties o 土 computedradlo graphy images and medical image processing ， we h 。 e study the filtering methods r competed radlography images noises our mmor wo indudes ： 1 on the base of analyzing computed radlography imaging system in detail ， the author th 让出 that the mnyor … noises are gausslanwie noise and polsson noise then ， the dlfferemrelationshlp ofbe 加 eentwo kinds ofnolses and sipal were studied completely 21 by conslderingboththe charactenstlcs ofcomputed radlography images andthe statistical feres ofwavelettransformed images ， a multlscale image iltenng algonthln ， which based on wo state hidden markov model （ hmm ） and mlxtule gausslan statistical model ， has been used to decrease the gausslan white noise in compmed images we expenmems as well as the comparison ith other denolsing methods werepresentedatlast ，
在cr成像过程中，不可避免地引入各种噪声干扰，极大地影响了医生诊断的准确性，为此，只有弄清干扰图像信息的各种噪声的来源、特征及其与信号的相互关系，才能有效地将之消除。结合cr影像以及医学图像处理的特点，本文研究了cr影像噪声滤除的方法。主要工作有： [ 1 ]在详细地分析cr成像系统的基础上，指出固有噪声和泊松噪声是影响成像质量的两种主要噪声，并深入地讨论了这两种噪声与图像信号之间的相互关系。
