Patent number: 11944486Abstract: An analysis method and an electronic apparatus for breast image are provided. The method includes the following steps. One or more breast ultrasound images are obtained. The breast ultrasound images are used for forming a three-dimensional (3D) breast model. A volume of interest (VOI) in the breast ultrasound image is obtained by applying a detection model on the 3D breast model. The VOI is compared with a tissue segmentation result. The VOI is determined as a false positive according to a compared result between the VOI and the tissue segmentation result. The compared result includes that the VOI is located at a glandular tissue based on the tissue segmentation result. In response to the VOI being located in the glandular tissue of the tissue segmentation result, the VOI is compared with the lactiferous duct in the 3D breast model.Type: GrantFiled: July 19, 2021Date of Patent: April 2, 2024Assignee: TAIHAO MEDICAL INC.Inventors: Jen-Feng Hsu, Hong-Hao Chen, Rong-Tai Chen, Hsin-Hung Lai, Wei-Han Teng
