How can I extract the specify region of interest (ROI) as separate data set

Hi,
I have a Matlab code reading an echosounder data file, and plotting out whole sweeps at time on the screen. The data are decoded and stored in array D, and the X, Y coordinates for this data are calculated from the angles 'pangle' decoded from each pings' header, and fractions of the range setting. These data are stored in matrices (the size of each matrix is 500x140). Here is my question: How can I select a preferred area from the whole sweep using ROI, and separate it, in order to work only on selected region of data?
Kind regards, Michal
