%USAGE :  [hi_res] = bft_sub_image(hi_res, lo_res, element, start_time)
%
%INPUT  : hi_res  - High resolution RF image. One column per scan line
%         lo_res  - Low resolution RF image. One column per scan line
%         element - Number of element, used to acquire the low resolution
%                   image
