OBJECTIVE: To find out the advantages, dangers, and limitations related to wrapping a affected person with lead shielding throughout fluoroscopy-guided kyphoplasty procedures as a method to scale back operator radiation publicity.
MATERIALS AND METHODS: An anthropomorphic phantom was used to imitate a affected person present process a kyphoplasty process below fluoroscopic steering. Radiation measurements of the air kerma charge (AKR) had been made at a number of places and below numerous experimental situations. First, AKR was measured at numerous angles alongside the horizontal airplane of the phantom and at various distances from the phantom, each with and with no lead apron wrapped across the decrease portion of the phantom (referred to right here as phantom shielding). Second, the impact of an operator’s apron was simulated by suspending a lead apron between the phantom and the measurement gadget. AKR was measured for the 4 shielding conditions-phantom shielding solely, operator apron solely, each phantom shielding and operator apron, and no shielding. Third, AKR measurements had been made at numerous heights and with various C-arm angle.
RESULTS: In any respect places, the phantom shielding supplied no substantial safety past that supplied by an operator’s personal lead apron. Phantom shielding didn’t scale back AKR at a top similar to that of an operator’s head.
CONCLUSIONS: Earlier reviews of utilizing affected person shielding to cut back operator publicity fail to think about the function of an operator’s personal lead apron in radiation safety. For an operator sporting acceptable private lead attire, affected person shielding supplies no substantial discount in operator dose.
