  • Abstract:
    Quality Controls (QCs) for the evaluation of Color Doppler (CD) performance play a pivotal role since CD is one of the most widely used Doppler techniques in medical imaging. Among the recommended test parameters, directional accuracy at 90° is included, even if its assessment is carried out visually. Therefore, in this study, a novel CD test parameter, called blind angle, has been proposed and defined as it allows testing the Doppler frequency shift dependency on the insonation angle. Moreover, a novel automatic method for the estimation of this parameter through the post-processing of CD videos has been proposed. Data have been collected from a single ultrasound diagnostic system equipped with a phased array probe. Tests have been carried out for two probe frequencies and three constant flow rate regimes set on a flow phantom. Based on the preliminary promising outcomes, further studies are going to be carried out.
