怎样读dicom格式图片？

怎样读dicom格式图片？
clear all
I = dicomread('wo.dcm');
imshow(I,'DisplayRange',[])
这样可以读出来，但是很模糊，有没更好的程序呢？
哪位大侠能帮帮小弟我啊？

提取dicom格式图片的信息

各位大侠，要提取dicom格式图片的信息除了dicominfo还有什么函数呢？因为dicominfo读不出病人的姓名。有哪位能帮我写个程序吗？谢咯

xiezhh 发表于 2009-4-25 07:43

提取图像信息就用dicominfo函数，它能读出病人姓名，我刚刚测试过，另外dicomread函数可以读取图像数据。
再举个例子吧
x=dicominfo('CT-MONO2-16-ankle.dcm')
x.PatientName

dicom

各位大侠，要提取dicom格式图片的信息，用dicominfo函数读出来很杂很乱信息又多，怎样才能提取一些有用的基本信息呢？用怎样的程序好呢？

xiezhh 发表于 2009-4-28 18:15

读出的信息很丰富，一点都不乱，是结构体数据，按你所需要的字段提取就行了，可以将提取的信息写入Excel表格（需编程）。

真的很乱

ChaChing 发表于 2009-4-29 20:44

个人猜测LZ可能不清楚结构资料(structure), 才会觉得乱!
建议看下help中的MATLAB->Programming->Structure里面的内容, 学学结构array的使用!
