Beware of cheap marketing ploys on your ultrasound system.
For example, one of the most common requests is to get an Easy 3D package on their ultrasound, such as many of the GE Logiq ultrasounds, Logiqbook XP, and others. This is not 4D. It is not easy.
Let me repeat that.
EASY 3D is not 4D, and it is NOT EASY.
This is one of the more requested features for those looking for a budget 3D/4D ultrasound. It is a relatively useless feature and tremendously frustrating. It is really 3D ultrasound version 1.0, in which you have to manually sweep the probe. One movement, breath, anything will create a horrible image, and you have to manually render and cut the image. It's maddening and I tell people to pretend it's not there.
This is not a ploy to sell you a Voluson, iu22, P5, or X300 ultrasound with 4D. Really. Easy3D is not good for your "babyface" stuff if that's what you're looking for.
