Hii,
You can use imread function to read image file and store them as an array variable.Use rgb2gray function to convert RGB image or colormap to grayscale.

Do you know what format the file is in? The only thing that the extension implies is that it's 16 bit unsigned integer. It doesn't say anything about it having any format.
I'm inclined to assume it's just raw data, in which case you can probably just treat it like any .bin file and read it with fread(). You'll need to know its geometry in order to get anything useful out of it.
If you know what you're looking for, you might be able to peek at it with a hex editor to see if there's anything revealing in the beginning of the file.
If the file isn't confidential (or huge), you may consider attaching it.

I confirm that with the command fread (), with the right size, the file is correctly read.
The idea on the hex editor is interesting.
Thank you
