Which statement about tight curvature in transducers is true?

Tight curvature increases the field of view while keeping the probe size small Tight curvature decreases the field of view Tight curvature increases the probe size Tight curvature has no effect on field of view

Correct Answer:

Tight curvature increases the field of view while keeping the probe size small

Explanation:

A tight curvature enlarges the angular coverage of the emitted ultrasound beams. When the array elements are arranged along a small-radius arc, the beams come from a wider range of angles across the imaging plane. That broader angular sampling translates into a larger field of view at a given depth, so you get more of the anatomy visible in one sweep without needing a bigger, bulkier probe. In other words, you gain a wider image area while keeping the overall size of the probe compact. This is why a transducer with a tight curvature is described as increasing the field of view without increasing probe size.
