Which statement is NOT true of a linear phased array transducer?

The footprint tends to be small.
It can alter the number of focal zones and the depth.
The image is a rectangle.
It uses electronic steering.

The correct answer is: The image is a rectangle.

A linear phased array transducer is a type of ultrasound transducer that has a rectangular shape and its image is rectangular, not square. Option C is incorrect, as it is a true statement about a linear phased array transducer. Option A is true as a linear phased array transducer has a smaller footprint compared to other types of transducers. Option B is also true as a linear phased array transducer has the ability to alter the number of focal zones and the depth of the image. Option D is also true as a linear phased array transducer uses electronic steering to steer the ultrasound beam, allowing for better imaging and improved resolution. Therefore, option C is the only incorrect statement about a linear phased array transducer.
