摘要： A computer-aided detection system to detect clustered microcalcifications in digital breast tomosynthesis (DBT) is disclosed. The system performs detection in 2D images and a reconstructed 3D volume. The system may include an initial prescreening of potential microcalcifications by using one or more 3D calcification response function (CRF) values modulated by an enhancement method to identify high response locations in the DBT volume as potential signals. Microcalcifications may be enhanced using a Multi-Channel Enhancement method. Locations detected using these methods can be identified and the potential microcalcifications may be extracted. The system may include object segmentation that uses region growing guided by the enhancement-modulated CRF values, gray level voxel values relative to a local background level, or the original DBT voxel values. False positives may be reduced by descriptors of characteristics of microcalcifications. Detected locations of clusters and a cluster significance rating of each cluster may be output and displayed.

摘要： A projection lamp with a dual projection function, including a base. The base is provided with a first light-emitting element and a first projection film. Emitted light of the first light-emitting element can pass through the first projection film to be projected outward. The base is provided with a slide projection unit, which includes a light-emitting assembly and a second projection film. Emitted light of the light-emitting assembly can pass through the second projection film to be projected outward. The emitted light of the first light-emitting element passes through the first projection film to be projected outward to form a projection pattern corresponding to the first projection film, and at the same time, the emitted light of the light-emitting assembly passes through the second projection film to form the projection of the slide.

摘要： The present invention discloses a large-field unit-magnification projection optical system. The optical system includes an optical axis, a spherical concave reflection mirror; a lens group with positive refracting power arranged adjacent the mirror with an air space therebetween. The lens group includes a first plano-convex lens, a negative meniscus lens adjacent the plano-convex lens, a positive lens adjacent the negative meniscus lens, a negative double-convex lens spaced apart far from the positive lens, and a second plano-convex lens. The optical system further includes a pair of prisms each having respective first and second surface. The second surfaces are arranged adjacent the flat surface of the plano-convex lens element on opposite sides of the optical axis and the first surfaces are arranged adjacent object planes and image planes, respectively. Each lens in the lens group and the pair of prisms provide chromatic aberration correction in a spectral region that contains at least g, h and i-line wavelengths. In this projection optical system, the object plane is parallel to the image plane.
