WFUMB Safety Committeeでは，これまでに超音波の安全性に関する文書を作成して，機関誌Ultrasound in Medicine and Biology （UMB）やホームページを利用して公開してきている．
（1）WFUMB recommendations on the safe use of ultrasound（UMB 24, suppl.1,pp.xv-xvi,1998）
（2）Recommendation on the safe use of ultrasound contrast agents（UMB 33,pp.173-174,2007）
（3）WFUMB policy statement on non-medical use of ultrasound（WFUMB Website, 2008）
現在，各国で作成されている超音波の安全性に関する文書をとりまとめて，ホームページに公開することを目的に活動が行われている．2010年度は以下のような文書を作成した．
（1）WFUMB recommendations on non-medical use of ultrasound
・The WFUMB disapproves of the use of ultrasound for the sole purpose of providing keepsake or souvenir images of the fetus.
・Ultrasonography is a medical procedure that should only be carried out in the clinical setting where there is a medical indication and when carried out under the supervision of a physician or an expert.
・The use of ultrasound to provide keepsake images or videos of the fetus may be acceptable if it is undertaken as part of the normal clinical diagnostic ultrasound examination, provided that it does not increase exposure to the fetus.
・In the absence of supporting evidence of safety, caution should be used to minimize ultrasound exposure to the fetus.
・When using ultrasound for non-medical reasons the ultrasound equipment display should be used to ensure that TI＜0.5 and MI＜0.3.
・Ultrasound imaging for non-medical reasons is not recommended unless carried out for education, training or demonstration purposes.
・Live scanning of pregnant models for equipment exhibitions at ultrasound congresses is considered a non-medical practice that should be prohibited since it provides no medical benefit and affords potential risk to the fetus.

そして，以下の文書を作成中である．
（2）WFUMB statement on the safe use of Doppler ultrasound during 11-14 week scans （or earlier in pregnancy）
（3）WFUMB policy on live scanning at commercial exhibitions（WFUMB Website, 2010）
これらの文書も本会のホームページで公開していく予定である．
