Abstract:
1. An ultrasound image registration apparatus, suitable for registering two ultrasound images partially overlapped with each other, the ultrasound image registration apparatus comprising: a first-stage image-developing processing module, configured for performing beam-forming processing on the ultrasound images so as to generate two raw images; a second-stage image-developing processing module, connected to the first-stage image-developing processing module, configured for performing envelope detection processing and compression processing on the raw images so as to generate two developed ultrasound images; and a registration module, connected to the first-stage image-developing processing module and the second-stage image-developing processing module, configured for respectively obtaining coordinate information of at least one feature point of the raw images as at least one initial value of an image registration procedure, and configured for performing speckles-reducing processing on the developed ultrasound images and using speckles-reduced ultrasound images to perform the image registration procedure, wherein the registration module comprises:
