The new system represents an investment of nearly $400,000 and is the largest single project included in Mayo Regional's 2008 capital equipment budget, which totals $2 million overall.

The digital fluoroscopy system was manufactured by GE Healthcare at a cost of $341,000. It is connected to a carbon reader manufactured by Fuji, priced at $56,000, which allows radiology technologists to view and manipulate the x-ray images.

Fluoroscopy is used for medical diagnosis and generates live images of the internal structure of the human body. Technologists introduce a contrast medium to the patient, and x-rays cast a shadow of internal organs upon a fluorescent screen. The resulting images are examined by a physician to aid in the diagnosis of medical conditions.

Joann Lovell, RTR, manager of Mayo's Radiology Department, said the new fluoroscopy system improves operational efficiencies and can cut examination times in half. Image clarity is improved, as the upgraded technology selects the optimal focal spot and dose rate for each patient. A pediatric mode makes automatic adjustments to reduce radiation doses for smaller patients.

The equipment's control console allows technologists to spend more time with patients at table side during examinations. The transfer of images and patient information is enhanced.

Lovell said Radiology has also scheduled installation of a new digital mammography unit for Mayo's Imaging Center for Women. That equipment, also manufactured by GE Healthcare, is budgeted at $455,000 and is expected to be in service by October.
