ValueError：无法将输入数组从形状256,256,3广播到形状256,256

如何解决ValueError：无法将输入数组从形状256,256,3广播到形状256,256

我正在尝试读取一些DICOM文件，并将它们转换为numpy数组。但是当我去存储图像的原始数据时，会发生此错误：

回溯（最近通话最近）：文件“ C：/Users/Matheus/PycharmProjects/mesTrado/AreaDeInteresse/testando3.py”，第47行 d_array [:,：，dcms.index（dcm）] = np.array（b.pixel_array） ValueError：无法将输入数组从形状（256,256,3）广播到形状（256,256）

我的代码是对代码的重读： https://gist.github.com/somada141/8dd67a02e330a657cf9e

for dcm in dcms:

for numero,image in enumerate(d_array):

有人可以帮助我解决此错误吗？
