Ultrasound has been controversial in the past in some instances because it is a relatively easy-to-use technology, so that anybody can use it, it seems. However, in order to safely use it and know what you're looking at requires training. There also has been some controversy with regard to the use of the information that can be gotten from ultrasound examinations. Such as examination of the developing foetus. In Massachusetts a law had been passed where a pregnant woman who was seeking abortion had to have an ultrasound examination and look at that ultrasound examination to be sure that they wanted to terminate this pregnancy.
