High Level Fluoro

High Level Fluoro technique used for when higher power is needed in dense anatomy (obese patients) typically does not exceed 1 - 1.2 kW. For example, 80 kV @ 12.5 mA. This is important as federal limit on HLF (high level fluoro) dose rate is 20R/min. HLF is designed to run higher level fluoroscopy to improve anatomical visualiztion while decreasing patient dose. Some systems like the Ziehm Quantum, when using a 30 ms. pulse width, actual dose mA to the patient is reduced by a factor of nearly one-third.
