In plain language
In a phantom study, flexible tungsten paper placed beside a simulated patient roughly halved scattered radiation at operator eye level and cut waist-level scatter by about 70%, with no benefit at knee level. Clinical staff doses were not measured.

What it found
Five sheets of tungsten functional paper taped to the operator side of the phantom reduced scattered air kerma rate substantially at eye, chest and waist levels in cine mode.
Key figures: 50.4% eye, 46.1% chest, 70.7% waist, 2.1% knee (5 sheets, cine)
Results were similar in fluoroscopy mode.
Key figures: 51.1% eye, 45.2% chest, 71.7% waist, 2.8% knee (5 sheets, fluoroscopy)
TFP placed at the side of the phantom gave essentially no reduction at knee level, as below-table scatter did not pass through the sheets.
Key figures: about 2% reduction at knee
Shielding saturated around five sheets; going from 5 to 10 sheets added only about 10% further reduction.
Key figures: further reduction of only 10%
Monte Carlo simulation agreed closely with measurements.
Key figures: within 3%
Limits to keep in mind
Single phantom and fixed C-arm geometry with no clinical staff measurements; measurement uncertainty about 15%, and an author has a financial interest in the paper's manufacturer.
