While it is stated: "... technology has advanced and now the images are processed and displayed on a large screen in high-definition video.", the cost of the technology and the "overage" in cost per procedure goes hand in hand. It may now only take 15 minutes to preform what used to take 75 minutes, but if the doctors are only reimbursed for their time for the procedure, they would never be able to afford the technology which would put them back to 75 minute procedures.
This technology not only helps to produce more accurate test results, but allows more patients to be able to have these tests each day. That all comes at a cost. If a procedure is reimbursed $100 for a supposed 60 minute procedure using older technology, and that procedure now only takes 15 minutes using newer technology, More of the $100 has just been shifted from doctor salary to technology cost.
Instead of cutting the cost of the procedures, they need to find the doctors and facilities that are scamming the system, billing for procedures that aren't actually performed. (Like Columbia/HCA that Governor Rick Scott of Florida resigned from as Chief Executive in 1997 amid a controversy over the company's business and Medicare billing practices. He was not implicated, but the company ultimately admitted to fourteen felonies and agreed to pay the federal government over $600 million.)
