Embodiment 1
[0056] This embodiment discloses an automatic splicing method for ABUS breast ultrasound panoramas, which can splice coronal ultrasound images (C-plane ultrasound images) at different scanning positions and at the same scanning depth into a panoramic image. Splicing methods include:
[0057] For each ultrasonic image in the ultrasonic image set to be spliced, the position of the feature point is respectively located, and the position of the feature point is used as a matching feature point for splicing and exists in each ultrasonic image. Generally speaking, in order to facilitate accurate identification, nipples are selected as feature points. Taking the nipple as a feature point as an example, the method of locating the feature point includes: extracting the region of interest of the ultrasound image, and preprocessing the extracted region of interest, and then using the circle detection method to locate the position of the suspected nipple; for the suspected nipple located ...
Embodiment 2
[0061] See attached figure 1 , this embodiment discloses an automatic splicing method for ABUS breast ultrasound panoramas, which can effectively and automatically stitch ABUS breast ultrasound panoramas without manual intervention, and solve the problem that the entire breast region cannot be fully presented due to the limited imaging field of view of ABUS breast ultrasound images Insufficient, doctors can general panorama Figure 1 It has a very important clinical application value to visually view the entire breast tissue structure of the examinee at one time, so as to achieve a more accurate and objective diagnosis of breast cancer screening cases.
[0062] Concrete steps of the present invention include:
[0063] An automatic stitching method for ABUS breast ultrasound panoramas, which can effectively and automatically stitch ABUS breast ultrasound panoramas without manual intervention, and solves the problem that the entire breast area cannot be fully presented due to t...
Embodiment 3
[0073]The present embodiment discloses a method for automatic splicing of an ABUS breast ultrasound panorama, comprising the following steps:
[0074] Step 1: Read a new case of ABUS breast ultrasound image data.
[0075] Step 2: Determine whether the read data contains different scanning positions to be spliced, such as: AP (front and back), Lateral (side), Medial (middle), such as Figure 4 and Figure 5 shown. If it is judged that the example data contains different scanning positions to be spliced, proceed to the next step, otherwise return to step 1 (single image does not need splicing).
[0076] Step 3: According to the prior knowledge, automatically select the C-plane ultrasound image data from the correctly read ABUS breast ultrasound image data. An example of ABUS image data after correct reading contains image data of H plane (transverse section), S plane (sagittal plane), and C plane (coronal plane), such as image 3 As shown, in this step, the C-plane ultrasoni...
