Multiple Choice

In a linear sequential array transducer, the sound beams are usually directed ________.

Explanation:
The main idea here is how a linear sequential array directs its ultrasound energy. In this type of transducer, the elements lie in a straight line along the probe face and fire in sequence. The beam that results travels perpendicular to the surface of the array—straight ahead into the body. This fixed direction creates a rectangular imaging field directly in front of the probe. While other transducer designs or phasing can steer beams to different angles, a simple linear sequential array directs beams straight ahead by default.
