Embodiment Construction

[0023] like Image 6 As shown, it is a flow chart of the spatial compounding method for ultrasound imaging according to this embodiment, including compounding step 602 and rotational stretching step 606 , and also optionally includes deflection step 600 and storage step 604 . In the deflection step 600, the transmit scan line is focused to a predetermined deflection angle by controlling the transmit pulse delay, and the receive scan line is deflected to substantially the same angle as the transmit scan line by controlling the beamforming delay for spatial recombination; In the compounding step 602, weighted compounding is performed on the scan-converted multi-angle images; in the storing step 604, a group of rotational stretching parameters obtained from multiple sets of images are stored for real-time rotational stretching; In the stretching step 606 , the gray-scale distribution of the weighted and composited image is adjusted to be substantially consistent with the gray-sca...

Abstract

The invention discloses a spatial fusion method and a spatial fusion device for ultrasonic imaging and an ultrasonic imaging system comprising the device. The method comprises a fusion step and a rotary stretch step, wherein the fusion step is used for weighing and fusing a scanned and converted multi-angle image; and the rotary stretch step is used for adjusting the gray-scale distribution of the weighed and fused image make the gray-scale distribution basically same as the gray-scale distribution of the image to be fused through rotation and stretching under the condition of not changing image mean value gray-scale mapping. By using the technical scheme, the image gray-scale level of which the space is fused can be retained, and the contrast resolution of the image is ensured.

Description

technical field [0001] The present invention relates to ultrasonic imaging technology, in particular to a spatial compounding method and device for ultrasonic imaging, and an ultrasonic imaging system including the device. Background technique [0002] Spatial composite imaging is an imaging method that scans the scanned object along different angles, and then superimposes the pixels corresponding to the images of these different angles to form an image. Spatial compounding can suppress the influence of speckle noise, clutter and other ultrasound artifacts on image quality, enhance the resolution between tissues, significantly improve the clarity of low-contrast tissues and small lesions in ultrasound images, and clearly show the differences between tissues. boundary. [0003] figure 1 It is a block diagram of a traditional spatial composite ultrasonic system, with a multi-element ultrasonic transducer (probe), and the main control system can switch the transmission and re...
