ABSTRACT
Fig. 3.1 Modalities used in vascular ultrasound to study blood vessels and blood flow.
CONTROLS FOR ULTRASOUND MACHINES Ultrasound machines have a preset menu for each anatomical site although some
sonographers prefer to create their own settings. Machines made by different manufacturers may have different names for the controls but
they all serve the same purpose. Some machines do not have all of the functions listed whereas others have controls not
mentioned here.
