Two-dimensional (2D) ultrasonography is the fundamental technology on which diagnosis, management, and control in reproductive medicine depends. Over the years there have been efforts to improve 2D ultrasound image quality. In recent years, a series of software has appeared that has generated enormous interest. The goal of these modes has been to improve image quality and diagnostic accuracy. HDlive incorporates a movable virtual adjustable light source which, as it penetrates, produces selective illumination with respective shadows that result from the structures where light is reflected. This combination of light and shadow results in spectacular images which appear much more real than those obtained with conventional 3D ultrasonography.
