Question

我尝试使用image_slicer函数将DICOM图像拆分为图块，但它没有识别DICOM。

我已经读过DICOM并将它们转换成np数组：

dcm_files [0]

array([[-1024, -1024, -1024, ..., -1024, -1024, -1024],
       [-1024, -1024, -1024, ..., -1024, -1024, -1024],
       [-1024, -1024, -1024, ..., -1024, -1024, -1024],
       ...,
       [-1024, -1024, -1024, ..., -1024, -1024, -1024],
       [-1024, -1024, -1024, ..., -1024, -1024, -1024],
       [-1024, -1024, -1024, ..., -1024, -1024, -1024]], dtype=int16)

并且能够通过以下方式查看图像：

from PIL import Image
import numpy as np

img = Image.fromarray(dcm_files[0])
img.show()

然后尝试切片：

import image_slicer
image_slicer.slice(img, 64)

错误：＆＃39;图片＆＃39;对象没有属性＆＃39;读＆＃39;

谢谢！

模块image_slicer使用文件名，而不是文件实例。因此，您必须将阵列保存到某些本地化。您可以使用tempfile module来实现此目的。

from PIL import Image
import numpy as np
import image_slicer
import tempfile

array = np.random.randint(0,200, size=(128,128), dtype='int32')

img = Image.fromarray(array)

temp = tempfile.NamedTemporaryFile()
img.save(temp.name, format="png")

image_slicer.slice(temp.name, 4)
#if you want to play with the slices:
tiles = image_slicer.slice(temp.name, 4, save=False)

如何将dicom图像分割成瓷砖？
