In that scenario, your surgeon would see the program suddenly freeze.<p>The program likely looks like this:  data acquisition -&gt; transformation -&gt; display transformation on monitor.<p>If the transformation step fails, the monitor will end up displaying (a) nothing, (b) random data, or (c) the most recent image.  None of these help the surgeon continue surgery.  It&#x27;s the same as a crash.<p>If your environment fails, there&#x27;s nothing you can do to recover.  Planes aren&#x27;t designed to survive the loss of a wing.  Why is this case any different?
