In both cases, the images created are denominated amplitude mode (referred to as A-mode) images. These are the simplest type of ultrasound image. To generate A-mode images, one or more transducers work independently, scanning a line through the medium, with the ultrasound echoes plotted on a screen as a function of depth. In such methods, the ultrasound signals travel through the fluid independently of each other, and no type of constructive interference arises. The resolution of the produced images tends to be extremely poor due to the separation between adjacent transducers and the size of the one or more transducer elements (often bigger than 15 mm). Accordingly, the one or more transducers may detect ultrasound from an area which is larger than the objects to be detected, such as particles or bubbles.
