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 1):
A digital slide scanning apparatus comprising:\n a stage configured to support a glass slide; a high-resolution camera; a first lens defining a macro image optical path to the high-resolution camera, wherein the first lens is configured to provide a field of view to the high-resolution camera, and wherein the field of view 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, wherein the second illumination system is configured to angle illumination light in a pattern such that substantially none of its illumination light is reflected along the optical path to the high-resolution camera; and at least one processor configured to, while a stage is supporting a glass slide,\n while the field of view is illuminated by the first illumination system, capture 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, \n while the field of view is illuminated by the second illumination system, capture 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, \n identify image artifacts in the second macro image, and, \n based on the identified image artifacts in the second macro image, correct the first macro image to generate a modified first macro image.
