What is the main advantage of using a linear array transducer over a curved array transducer?

The main advantage of using a linear array transducer over a curved array transducer is better spatial resolution. Linear array transducers emit ultrasound waves in a straight line, which allows for higher resolution imaging of structures close to the surface. This configuration is particularly useful for imaging superficial structures such as vascular tissues, musculoskeletal components, and superficial organs, where clarity and detail are essential for accurate diagnosis.

In contrast, curved array transducers, while providing a wider field of view, are designed for deeper penetration, which often sacrifices some spatial resolution. The curved shape allows for the examination of larger areas, but typically results in lower resolution images compared to the linear transducer, especially at higher frequencies. Consequently, when the priority is high detail in localized areas, a linear array transducer is often preferred.
