在matlab中将一系列dicom图像转换为特定格式

Question

我有一系列属于单个患者的 matlab 图像。我在网上找到了一些代码，但它播下了一些错误。我想要这样的东西，Image

这是我的代码。

% Preallocate the 256-by-256-by-1-by-20 image array.
X = repmat(int16(0), [256 256 1 20]);
% Read the series of images.
for p=1:20
filename = sprintf('brain_%03d.dcm', p);
X(:,:,1,p) = dicomread(filename);
end
% Display the image stack.
montage(X,[])

我从这里找到这段代码： https://www.mathworks.com/company/newsletters/articles/accessing-data-in-dicom-files.html

Error using montage>validateColormapSyntax (line 339)

索引图像可以是 uint8、uint16、double、single 或 logical。

    Error in montage>parse_inputs (line 259)
    cmap = validateColormapSyntax(I,varargin{2});

   Error in montage (line 114)
  [I,cmap,mSize,indices,displayRange,parent] = parse_inputs(varargin{:});

  Error in Untitled2 (line 9)
  montage(X,[]);

Answer 1

调用montage function has changed since that code sample was written (back in 2002!). As noted in the comments section of the File Exchange submission for the sample DICOM data files的语法，新的正确语法是：

montage(X, 'DisplayRange', []);

您收到该错误是因为新语法将 montage(X, []); 解释为就好像 X 是索引彩色图像（不允许是带符号的 int16 类型，根据到错误）与一个空的颜色映射 [].
