Explanation of Diagram
This student-drawn diagram shows a curved or convex array transducer emitting ultrasound pulses on the left, and the shape of the scan it produces on the right.
The illustration of a convex or curved array transducer on the left demonstrates the placement of piezoelectric elements in a convex/curved array transducer – elements are next to each other, curving out in a convex shape with pulses being emitted out in a spreading sunburst-type manner. A complete name for this transducer is the convex 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 sector scan. It can also be called a modified sector scan, as the image is not a complete sector shape due to the concave area cut-out at the top.
