摘要：
An ultrasound imaging method in which ultrasound signals are transmitted into a living organism, reflected from fluid flowing along a path within the organism, and received by an ultrasound transceiver system with a resolution limit in a first direction. These signals are used to generate data representing a sequence of images over time； each image including a speckle pattern arising from interference within the reflected ultrasound signals. A peak-sharpening operation is applied to the image data, generating data representing a sequence of resolution-enhanced images, each having a resolution in the first direction finer than the resolution limit of the transceiver system in that direction, and including a respective peak-sharpened speckle pattern. A combining operation is applied to generate data representing an output image in which the path of the fluid is represented by a superimposition of the peak-sharpened speckle patterns from the resolution-enhanced images.
