Abstract:
Two-pass capture of a macro image. In an embodiment, a scanning apparatus comprises a stage, a high-resolution camera, and a lens that provides a field of view, substantially equal in width to a slide width, to the high-resolution camera. The apparatus also comprises a first illumination system for transmission-mode illumination, and a second illumination system for reflection-mode illumination. Processor(s) move the stage in a first direction to capture a first macro image of a specimen during a single pass while the field of view is illuminated by the first illumination system, and move the stage in a second direction to capture a second macro image of the specimen during a single pass while the field of view is illuminated by the second illumination system. The processor(s) identify artifacts in the second macro image, and, based on those artifacts, correct the first macro image to generate a modified first macro image.

Claim (Index 15):
A method for generating a macro image in a digital slide scanning apparatus that comprises a stage configured to support a glass slide, a high-resolution camera, a lens defining a macro image optical path to the high-resolution camera and configured to provide a field of view to the high-resolution camera that has a width that is substantially equal to a complete width of a glass slide, a first illumination system optically coupled with the first lens and configured for transmission-mode illumination of the field of view from below a glass slide on the stage, a second illumination system optically coupled with the first lens and configured for reflection-mode illumination of the field of view from above a glass slide on the stage, and at least one processor, the method comprising, by the at least one processor of the digital slide scanning apparatus:\n while the field of view is illuminated by the first illumination system, capturing a first macro image of a specimen on the glass slide using the high-resolution camera while the glass slide is under the first lens; while the field of view is illuminated by the second illumination system, capturing a second macro image of the specimen on the glass slide using the high-resolution camera while the glass slide is under the first lens; identifying image artifacts in the second macro image; and, based on the identified image artifacts in the second macro image, correcting the first macro image to generate a modified first macro image.
