Question

Select the type of transducer that produces an image that takes on the shape of a parallelogram when it is electronically steered.

1) Linear phased array
2) Linear sequential array
3) Annular phased array
4) Convex array

Answer 1

A linear phased array transducer produces a parallelogram-shaped image through constructive interference of multiple ultrasound sources, allowing electronic steering of the beam for detailed ultrasound imaging.

Step-by-step explanation:

The type of transducer that produces an image with the shape of a parallelogram when it is electronically steered is known as a Linear phased array. These transducers have multiple ultrasound sources which are phased to interfere constructively in a given, adjustable direction. This phasing allows the beam to be swept electronically across the area of interest, akin to how a computer constructs a detailed ultrasound image by measuring echoes as a function of position and depth, hence revealing the shape and density of internal structures.
