The size of the transducer element is referred to as

Explanation:
Aperture refers to the size of the active transducer face—the area that emits and receives sound. This size directly shapes the ultrasound beam: a larger aperture produces a narrower beam, which improves lateral resolution and the ability to focus at depth. A smaller aperture creates a wider beam with reduced lateral resolution. Apodization is about weighting element amplitudes to reduce sidelobes, not the element size; an array is the group of multiple elements used together, and channels are the separate transmit/receive paths. So the term for the size of the transducer element is aperture.
