Several recent technical advances in cardiac ultrasound allow data to be acquired at a very high frame rate. Retrospective gating, plane/diverging wave imaging, and multiline transmit imaging all improve the temporal resolution of the conventional ultrasound system. The main drawback of such high frame rate data acquisition is that it typically has reduced image quality. However, for given clinical applications, the acquisition of temporally-resolved data might outweigh the reduction in image quality. It is the aim of this paper to provide an overview of the technical principles behind these new ultrasound imaging modalities, to review the current evidence of their potential clinical added value, and to forecast how they might influence daily clinical practice.
心脏超声的几项最新技术进步可以实现非常高的帧率数据采集。回顾性门控、平面/发散波成像和多线发射成像均改善了传统超声系统的时间分辨率。这种高帧率数据采集的主要缺点是图像质量通常会降低。然而，对于特定的临床应用，获得时间分辨数据可能比降低图像质量更重要。本文旨在概述这些新的超声成像模式背后的技术原理，回顾其潜在临床附加值的现有证据，并预测它们可能如何影响日常临床实践。
