the image showed in the screen but it is very dark…..I wonder way it is dark and not normal.
I checked with different dicom images but the problem remain.
I hope you can help me and
thanks in advance.

Answer 1

If you are dealing with monochrome images, you can set a linear scaling between a minimum and maximum pixel value as follows:

img = dicomread('filename');
imshow(img, [minAllowedPixValue maxAllowedPixValue]);

Alternately, you can display the image at full dynamic range:

imshow(img, []);
