The acquisition systems in almost all medical imaging, along with their noise reduction and such are built with FPGAs. An MRI machine costs several million dollars or more, and GE sells a handful each year, so spending $10,000 on the FPGA that it's built around makes more sense than millions on spinning an ASIC that will be out-of-date the day the machine is put in the field. Not to mention the need to maintain these machines for decades, given the replacement cost. Nothing else will do, when an applications processor is too slow to do data acquisition and an ASIC isn't cost effective.
