T19855 -It is now possible to switch between beamformed and image data. however, the workbench will crash or freeze in 9 out of ten times when attempting this -The excitation frequency of the transducer can now be set correctly -corrected wrong spacing, also set the image height and width to be that of the actually reconstructed lines and samples -added the ability to display information on the GUI, although I disabled it as it was too performance heavy
