Explanation of Diagram

This student-drawn diagram shows a linear array transducer emitting ultrasound pulses on the left, and the shape of the scan it produces on the right.

The illustration of a linear transducer on the left demonstrates the placement of piezoelectric elements in a linear array transducer – side by side, with pulses being emitted vertically and in parallel lines. A complete name for this transducer is the linear sequenced array transducer (‘sequenced’ meaning that it automatically emits pulses in sequence to form a real-time image of the patient).

The illustration on the right indicates the shape of the image produced, termed a linear or rectangular scan.
