Abstract: 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.

Abstract: A laser backlight plate includes a laser source, a light guide plate, least one reflective layer, and at least one light divergent structure. The laser source is configured for providing a laser beam. The light guide plate has a light emission surface, a backlight surface, and at least one side surface. The backlight surface is disposed opposite to the light emission surface, and the side surface extends between the light emission surface and the back light surface. The reflective layer at least partially covers the backlight surface and the side surface, and is configured for reflecting the laser beam impinging on the reflective layer to the light emission surface. The light divergent structure is configured for diffusing the laser beam, which is incident on the light guide plate from the light divergent structure, and is reflected to the light emission surface by the reflective layer.
