In medical applications, the amplitude of ultrasonic pulses is often constrained by mechanical considerations summarized by a mechanical index. We apply the ideal observer approach in a simulation environment to evaluating the role of mechanical index limits on task performance in b-mode ultrasonic imaging. We simulate a linear array operating at 15MHz and 60% fractional bandwidth, and consider three tasks related to breast sonography at a depth of 4cm. The ideal observer suggests that there
