hello guys i have a 3d image with .raw extension and whenever i need to read the image is mirroring so ill give my code and i hope you can help me guys

function [oct_volume] = read_oct_volume(iname, X, Y, Z) % read the OCT volume stored in the file iname (here *.raw) % X, Y and Z are the images parameters % in our case: X = 512, Y= 128, Z = 1024; means each volume contains 128 images % B-scan, each of dimension X=512 and Z=1024 oct_volume = zeros(Z, X, Y); fin = fopen(iname,'r'); for i=1:Y I = fread(fin, [X,Z],'ubit8=>uint8'); oct_volume(:, :, i) = imrotate(I, -90);

end fclose(fin); [a] = read_oct_volume('oct.raw',512,128,1024); % image_sequence=uint8(a); imshow(image_sequence(:,:,66))

the original image looks in oct.jpg the matlab view is in oct1.jpg i want oct1.jpg to look like oct.jpg

Thanks
