Got it! Yes, it does not load in VolView with this error on the Javascript console:

loggers.ts:13 RangeError: Invalid initial number of values for array (origin)
    at macros2.js:554:13
    at Array.forEach (<anonymous>)
    at setArray (macros2.js:552:14)
    at Object.setGetArray (macros2.js:619:3)
    at extend (ImageData.js:354:9)
    at Object.constructor [as newInstance] (macros2.js:917:5)
    at convertItkToVtkImage (ITKHelper.js:87:34)

The loader says the file has 4 dimensions. Must be a time series? VolView does not handle 4D images. Would be nice if it did or at least gave a nice error message to that effect.

知道了！是的，它无法在 VolView 中加载，并在 Javascript 控制台上出现以下错误：

loggers.ts:13 RangeError: Invalid initial number of values for array (origin)
    at macros2.js:554:13
    at Array.forEach (<anonymous>)
    at setArray (macros2.js:552:14)
    at Object.setGetArray (macros2.js:619:3)
    at extend (ImageData.js:354:9)
    at Object.constructor [as newInstance] (macros2.js:917:5)
    at convertItkToVtkImage (ITKHelper.js:87:34)

加载器表示该文件有 4 个维度。一定是时间序列吗？VolView 不处理 4D 图像。如果它确实做到了至少或者给出了一个很好的错误消息，那就太好了。
Thank you for your help, but a smaller 4D file can be loaded. I will send it to you for review.

test2.zip

For some reason the image reader library we are using shows the test2.zip file to hold a 3D image:

  "imageType": {
    "dimension": 3,
    "componentType": "uint16",
    "pixelType": "Scalar",
    "components": 1
  },
  "origin": [

    116.38414764404297,

  ],
  "spacing": [
    0.6640629172325134,

  "direction": "-0.9994939339115039,0.03180039970314527,0.0007813976456040354,-0.031809999592993764,-0.99919233310241,-0.024552098151576197...",
  "size": [

    220,
    256
  ],

Could this be changed to support loading 4D files? thank you.

It could, but I'm not aware of this being on anyone's current TODO list. We could support a community contributed PR or someone could fund Kitware for the work.
