david,
please contact your mdical physics expert and work with them to set your exposures. you also have an excellent local university deartment who publish widely on optimisation. tube voltage and filtration might be worth investigating, and new grids are often a revelation, but...
be very wary of lowering system dose. or removing grids - after all, the patients come to us for a diagnosis not a speckly grey image that might be the right bit of anatomy.
i am in hospital at the moment and have been shocked to find that my fellow sufferer in the next bed had been kept in for 2 days because they 'cant agree on the x-ray findings' - they finally sent him home with no treatment. so a non definitive false positive made him eat hospital food for 2 days.
