Abstract

Motion observed in real-time ultrasound images may be very misleading. The speckle pattern in images of soft tissue is an artefact and it may move in a way which bears no simple relationship to the motion of the tissues. The physical origin of this anomaly is described.

摘要

实时超声图像中观察到的运动可能具有很大的误导性。软组织图像中的散斑模式是一种伪像，其移动方式可能与组织的运动没有简单的关系。文中描述了这种异常现象的物理起源。
