The main idea here is penetration versus resolution. Lower frequencies penetrate deeper, while higher frequencies provide better detail but don’t go as far. The curvilinear probe uses a curved array with a lower frequency range and a large footprint, which gives you good penetration and a wide field of view. That combination makes it ideal for imaging deeper structures like the abdominal organs (liver, kidneys, pancreas) where you need to see through several centimeters of tissue. The other probes fit different needs: the linear probe uses higher frequencies for sharp, detailed images but only at shallow depths; the phased array probe has a small footprint and is great for focused, deep work like the heart but isn’t as suited for wide, deep imaging of large areas; the endocavitary probe is designed for internal cavities and uses higher frequencies for good resolution over shallow depths.
