  1. 关于数据集下载:https://adni.loni.usc.edu/data-samples/access-data/ 需要申请等待 adni 审批。
  2. mri扫描得到的是三维灰度图(XXX*1),例如.nii格式。图片(例如jpg)是二维的,不满足诊断需求。
  3. 我在 https://github.com/bytesc/lqdata 提供了少量测试数据集样例。

我已经通过审核了,按照您回答别的议题的方法下载得到的只有普通图片格式而不是nii格式。请问一下这个问题是怎么回事呢

我的是这个样子的,数据那里是ADNIDOD,请问是因为我申请数据时出问题了吗,而且我的数据好像跟您的比起来少了好多mmexport1704465186201.png

我下载的nii数据进行测试,出现了这样的问题。应该是我数据集不对的原因,请问一下申请的时候有什么注意事项吗?!mmexport1704514107375.png

nii是三维灰度图,应该是256x256x256x1。四维的张量。你上传的这个似乎是三维的张量。你可以打印输出你的nii图像的张量的shape检查。

其实你下载的什么无关紧要,最终输入的时候处理成三维灰度图就行。

是的,下载的数据集的shape好像不是很对,但是找不到正确的数据集下载方法了

可是下载数据不对的话,训练也会有问题的

只要数据信息内容有效,你可以处理成想要的格式。当然,你也可以修改模型和程序对其它格式和形式的数据进行适配。训练有问题是什么意思?

就是我是担心我下载的数据是有错误的,因为我发现官网有很多其他症状的数据,在看到您图片里是ANDI而且还有万这个量级的数据,但我是ANDIDOD且只有几百个数据的时候,就一直在怀疑是不是我的数据集申请有问题

有可能,我也不是很清楚adni官方是如何授权数据的。使用edu邮箱,标注尽可能明确科研用途可能会更好。

好的,我现在重新申请一下,可以麻烦一下您帮忙看一下申请的是那一些数据吗,我第一次申请的时候只勾选了带有阿尔茨海默的相关选项

有关数据下载,你会了吗
