MATLAB: Take CT# from from each pixel in CT DICOM image

Question

How do I tell MATLAB to take the CT# from each pixel in a CT DICOM image? I need to multiple the CT# for each pixel by the area of the pixel, which I assume is just one pixel. Please correct me if the area of one pixel is something else.

Answer 1

Use dicomread() to read in the image. The area of the pixel in real world coordinates (microns) will be in the header. The CT values of the pixels are the image itself.
