Abstract

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 are gains in performance and hence the quantity of diagnostic information as the limit on mechanical index is raised. However these gains are almost completely erased after computation of a standard b-mode envelope.
