How is an ultrasound image affected if several adjacent crystals of a linear array transducer...

Comprehensive and Detailed Explanation From Exact Extract:

In linear array transducers, each element controls a vertical portion of the image. If adjacent elements fail, the result is a vertical dropout corresponding directly below the damaged crystals.

According to sonography instrumentation reference:

“Damage to specific elements in a linear array transducer results in vertical dropout directly beneath the malfunctioning crystals.”

Therefore, the correct answer is A: Vertical dark zone directly below the damaged elements.
