The color Doppler portion of the image is parallelogram-shaped because the electrical spike patterns creating the doppler beams are which?

Explanation:
The color Doppler area is shaped by steering the ultrasound beams. The electrical spike patterns determine how the transducer elements fire to create multiple beams at different angles within the sector. Because these beams are angled relative to the image plane, the combined region they cover on the display ends up skewed, forming a parallelogram. If the beams weren’t steered, you’d see a rectangular footprint; steering makes the sides slope, hence the parallelogram shape.
