reorienting 3D image stack
显示 更早的评论
We have a set of xray images im(x,y)
They are a 3D set in height im(x,y,h) through hte plane of an object.
The object is on a xray platfrom and the planes are between the source and detector.
I can make a movie going through the planes without a problelm.
However, I want to be able to see it as if i was looking from the side of the image set rather than the top but I keep getting errors
figure, imshow(image2(50,:,:))
Error using images.internal.imageDisplayValidateParams>validateCData (line 118)
Multi-plane image inputs must be RGB images of size MxNx3.
clear
path = ['C:\Users\\OneDrive - \Desktop\alabama concepts\image sets\3D images\ImageData-Reconstructed slices DICOM\mini1\mini1\0\']
y = VideoWriter("newfile4.mp4", 'MPEG-4');
y.FrameRate = 3
y.Quality=100
open(y)
for n = 2:24+1
file = ['mini1_mini1_0_', num2str(n) '.DCM'];
im = double(dicomread([path, file]))/2^16;
im = imcrop(im,[200,500,2700-200-400,1800-500]);
imshow(im);
m = n-1;
image2(:,:,m) = im;
hold on;
text(50, 50, ' Example - - Mouse', 'FontSize', 16, 'Color', 'white');
text(50, 100, 'sample - \0\mini1_mini\', 'FontSize', 16, 'Color', 'white');
text(50, 150, ['ZAxis: ', num2str(n-1), 'mm'], 'FontSize', 16, 'Color', 'white');
text(50, 200, ['Contact - no magnification '], 'FontSize', 16, 'Color', 'white');
text(50, 250, ['33kv 900uA'], 'FontSize', 16, 'Color', 'white');
F = getframe(gca);
im2 = frame2im(F);
writeVideo(y,im2);
end
close(y)

Try adding 'squeeze' to you code.
The image array you are passing to imshow is m x n x p. Even though m=1, because it is 3D, imshow is assuming it is rgb image data, which can only have a size of 3 in the 3rd dimension.
figure, imshow(squeeze(image2(50,:,:)))
