Dear all,

I have the file as attached. the format is dicom (.dcm)

How to multiply all the pixel number of each slice with their own rescale slope(in dicominfo) in each slice?

**that means each slice have their own rescale slope value.

so that the new pixel value will come out when I view this images.

What leads you to believe the rescale slope and intercept might be different for each slice?

I'm, not sure that sir. That I guess

If just only one rescale slope for all slices, then how to multiply all the pixel number of each slice with rescale slope(in dicominfo)?

在 MATLAB Online 中打开

In general you should remember to include the intercept as well, although apparently that is 0 for this dataset.

unzip jaszakspect.zip
IM = dicomread('jaszakspect.dcm');
size(IM)
ans = 1×4
    64    64     1    64
info = dicominfo('jaszakspect.dcm');
[min(IM(:)) max(IM(:))]
ans = 1×2
       0   32767
IM = double(IM)*info.RescaleSlope + info.RescaleIntercept;
[min(IM(:)) max(IM(:))]
ans = 1×2
         0    0.0029
