For best results, include the slice of the DICOM image you want to work with, as an attachment or as an uploaded image.

If we want to extract pixel value, 'findND' is not required.
We can use :
X = dicomread('128X128', 'frames', 16);
region = X(58:70, 70:84);
disp(region);
This will print the pixel values in the specified region (rows 58 to 70 and columns 70 to 84) of frame 16.
