如何将DICOM文件转换为RGB？
我将在MATLAB中解释我的问题。我有一个多帧DICOM文件，70x70x50。我想将其转换为RGB。
这是我的代码：
clear all;
close all;
clc;
% Lettura Dicom
img = dicomread('provaDICOM.dcm'); % 4-D int16
info = dicominfo('provaDICOM.dcm');
img2 = squeeze(img); % 70x70x50 int16
img3 = mat2gray(img2); % 70x70x50 double
% volumeViewer(img2);
% Conversione RGB
cmap = copper(256);
numslice = size(img3,3);
colored_MHA = zeros(size(img3, 1), size(img3, 2), numslice, 3);
for slice = 1 : numslice
colored_MHA(:,:,slice) = ind2rgb(img3(:,:,slice), cmap);
end
这是错误：
Unable to perform assignment because the size of the left side is 70-by-70 and the size of the right side is
70-by-70-by-3.
Error in Dicom (line 18)
colored_MHA(:,:,slice) = ind2rgb(img3(:,:,slice), cmap);
I'll explain my problem in Matlab. I have a multi-frame DICOM file, 70x70x50. I would like to convert it to RGB.
This is my code:
clear all;
close all;
clc;
% Lettura Dicom
img = dicomread('provaDICOM.dcm'); % 4-D int16
info = dicominfo('provaDICOM.dcm');
img2 = squeeze(img); % 70x70x50 int16
img3 = mat2gray(img2); % 70x70x50 double
% volumeViewer(img2);
% Conversione RGB
cmap = copper(256);
numslice = size(img3,3);
colored_MHA = zeros(size(img3, 1), size(img3, 2), numslice, 3);
for slice = 1 : numslice
colored_MHA(:,:,slice) = ind2rgb(img3(:,:,slice), cmap);
end
This is the error:
Unable to perform assignment because the size of the left side is 70-by-70 and the size of the right side is
70-by-70-by-3.
Error in Dicom (line 18)
colored_MHA(:,:,slice) = ind2rgb(img3(:,:,slice), cmap);

您需要在
colored_mha上引用额外的维度。尝试：
更普遍 - 错误告诉您，您正在尝试将大一些东西放入太小的东西中，当您看到这一点时，您可以问自己为什么。
You need to reference an extra dimension on
colored_MHA.Try:
More generally - the error is telling you that you're trying to put something big into something too small, and when you see this you can ask yourself why that is.
