METHODS AND SYSTEMS FOR SPECKLE REDUCTION

Systems and methods for reducing speckle while maintaining frame rate are disclosed. Multiple sub-images associated with different receive angles are acquired for a single transmit/receive event at an observation angle. The sub-images are compounded to generate a final image with reduced speckle. In some examples, multiple sub-images from multiple transmit/receive events are compounded to generate the final image. The observation angle and/or the receive angles may vary between transmit/receive events in some examples. 公开了用于在维持帧速率的同时减少散斑的系统和方法。针对单个发射/接收事件以观察角度采集不同接收角度相关联的多幅子图像。将子图像进行复合以生成具有减少的散斑的最终图像。在一些示例中，将来自多个发射/接收事件的多幅子图像进行复合以生成最终图像。在一些示例中，观察角度和/或接收角度可以在发射/接收事件之间变化。
