Embodiment 1
[0032] like image 3 As shown, the contrast-enhanced ultrasound imaging method of this embodiment includes the following steps S101 to S105:
[0033] The initial step S101 is to set the projection period and acquire N frames of original contrast images, where N is the total number of frames in the imaging period. The specific method of obtaining the original contrast image can refer to the commonly used ultrasonic imaging method. For example, firstly, the probe sends ultrasonic pulses to the object to be detected, and the probe responds and receives the ultrasonic echo signal returned by the object to be detected. Then, the system responds to the received ultrasonic echo signal. The wave signal is processed to output the original image at multiple times. Original images include B-mode images (ie, tissue images), contrast images, and the like. Here, the specific structure of the probe, its transmitting and receiving process, and signal processing can be realized by correspond...
Embodiment 2
[0065] During the process of ultrasound imaging, the scanned image inevitably moves, which affects the effect of contrast-enhanced ultrasound imaging. Image motion can be caused by tissue movement with breathing or heartbeat, or by movement of the ultrasound probe. Therefore, it is necessary to perform motion matching on multi-frame scanned images.
[0066] like Image 6 As shown, the processing of the contrast-enhanced ultrasound imaging method in this embodiment includes the following steps S201-S205:
[0067] Initial step S201, which is similar to step S101 in Embodiment 1, and will not be repeated here.
[0068] In the motion registration step S202, motion registration is performed on the N frames of original contrast images obtained in step S201.
[0069] In a specific ultrasound imaging system / device, the activation or deactivation of the step of motion registration can be realized in various ways, for example, the system is preset to start motion registration to perf...
