  • Patent number: 11347044
    Abstract: A digital pathology imaging apparatus includes a single line scan camera sensor optically coupled with first and second optical paths. In a first embodiment, transmission mode illumination and oblique mode illumination are simultaneously used during a single stage movement that captures a low resolution macro image of the entire sample area and the entire label area of the slide via the first optical path. In a second embodiment, transmission mode illumination is used during a first stage movement that captures a low resolution macro image of at least the entire sample area via the first optical path and oblique mode illumination is used during a second stage movement that captures a low resolution macro image of at least the entire label area via the first optical path.

  • Publication number: 20220163779
    Abstract: Systems and methods for capturing a digital image of a slide using an imaging line sensor and a focusing line sensor. In an embodiment, a beam-splitter is optically coupled to an objective lens and configured to receive one or more images of a portion of a sample through the objective lens. The beam-splitter simultaneously provides a first portion of the one or more images to the focusing sensor and a second portion of the one or more images to the imaging sensor. A processor controls the stage and/or objective lens such that each portion of the one or more images is received by the focusing sensor prior to it being received by the imaging sensor. In this manner, a focus of the objective lens can be controlled using data received from the focusing sensor prior to capturing an image of a portion of the sample using the imaging sensor.

  • Patent number: 9366628
    Abstract: Systems and methods for standardizing one or more fluorescence scanning instruments to a reference system by separating the effects of drift and normalization. In an embodiment, a drift image comprising an image of a drift reference slide is captured by a system to be standardized. A drift measurement is calculated using the drift image. A first normalization image comprising an image of a normalization slide is also captured by the system to be standardized. A reference normalization image, also comprising an image of the normalization slide, is captured by a reference system. The first normalization image is compared to the reference normalization image to determine a gamma value and offset value for the system to be standardized.
