Question
I want to change the column-wise values of a DICOM image and assign them with new values to generate a new image. Columns (384) will be divided into 1-130, 131-230, 231-330, 331-384 and I want to multiply each (for example, all columns from 1-130 will be multiplied by * 0.15, to get a new value of the pixel). Please anyone may like to help. thanks

multfactor = repelem([0.15, 0.18, 0.04, 0.23], [130 100 100 54]); %modify factors appropriately newimage = oldimage .* multfactor;
If you need to write out the new image in the form of a dicom file, it can get a bit messy to get all of the details right. But use dicominfo() to get the information about the DICOM file, and pass the info in the dicomwrite() call.
