Abstract:
Objective:To introduce estimate a technique ofregulative aperture methodin locating lung block in TBI.Methods:We excavated a square aperture in the foam template which is used to fasten the lung block,and the projection formed by the field light through the aperture is used as the reference for adjusting the location of the lung block.Measure the windage of lung shades and block shades by X-ray,in 8 patients.Results:windage values of head-feet and left-right orientations are smaller inregulative aperture modethan in conventional method respectively.Conclusions:Regulative aperture methodis an easy and effective technique to improve lung shielding precision in TBI.
