Which imaging format emits pulses from different starting points and directions, combining linear sequential and linear phased array technologies to create a trapezoidal image?

• A. Vector Array
• B. Sector
• C. Linear Array
• D. Phased Array

Answer: (A)

Vector imaging uses pulses fired from multiple starting points and directions along the transducer, combining elements of linear sequential firing with electronic beam steering to produce a wide, trapezoidal field. By excitation from different origins, the system builds a composite image that expands laterally with depth, giving a broader view than a single-line or single-origin scan. This blending of multi-origin transmit and steering is what creates the trapezoidal image shape. Other formats tend to rely on a single origin or a single steering approach: a sector image uses a fan from one apex, a linear array yields a rectangular field along one line, and a phased array steers beams from the same origin to sweep angles. None of those inherently combine multiple starting points with multi-angle steering to form the trapezoidal field the way vector imaging does.
