An apparatus comprising a convex probe, a receiver and an image generating device. The convex probe includes a number of transducer elements configured to transmit a number of sets of ultrasound signals. Each set of the ultrasound signals includes a non-steered frame and at least one steered frame angled toward the non-steered frame. The receiver is coupled to the probe and configured to receive a non-steered echo frame for the non-steered fame and at least one steered echo frame for the at least one steered frame. The image generating device is coupled to the receiver and configured to generate a non-steered image using the non-steered echo frame and a needle-enhancement image using the steered echo frame and combine the non-steered image and the needle-enhancement image into a compound image.
