Which term describes a complete scan of the ultrasound beam, with the image composed of multiple scan lines?

• A. Frame
• B. Code Excitation
• C. Cine Loop
• D. Edge Shadow

Answer: (A)

A frame is a single, complete ultrasound image created by combining data from many scan lines. Each line samples echoes along a different beam path, and putting all those lines together forms the 2D image you see. When frames are shown in rapid sequence, you get a cine loop, which is used to review motion over time. Edge shadow is an artifact at the edges of structures caused by beam limitations, and coded excitation is a transmit technique to improve image quality. So the description of a complete scan composed of multiple scan lines corresponds to a frame.
