A networkable power controller includes a mode selector for selectively conducting of a plurality of input signals to an output of the networkable power controller, where the input signals and the output signals satisfy the same signaling protocol. The networkable power controller may be networked with other networkable power controllers, lighting ballasts and other building automation control devices, and user-controlled voltage selectors to provide a lighting control network. A power controller may include a mode selector that may be used in combination with other control devices or components, including a rotary dimmer control, a digital slide dimmer control, a demand load shedder component, a photometer component, and a communications interface. The communications interface allows digital control of the networkable power controller.

Systems and methods for improving quality assurance in pathology using automated quality assessment and digital image enhancements on digital slides prior to analysis by the pathologist are provided. A digital pathology system (slide scanning instrument and software) creates, assesses and improves the quality of a digital slide. The improved digital slide image has a higher image quality that results in increased efficiency and accuracy in the analysis and diagnosis of such digital slides when they are reviewed on a monitor by a pathologist. These improved digital slides yield a more objective diagnosis than reading the corresponding glass slide under a microscope.

A digital slide analysis system comprises an algorithm server that maintains or has access to a plurality of image processing and analysis routines. The algorithm server additionally has access to a plurality of digital slide images. The algorithm server executes a selected routine on an identified digital slide and provides the resulting data. Prior to the application of selected routine, the system employs a digital pre-processing module to create a metadata mask that reduces undesirable image data such that the image data processed by the selected routine has an improved signal to noise ratio. The pre-processing module uses a classifier that may be implemented as a pattern recognition module, for example. Undesirable image data is therefore excluded from the image data that is processed by the digital pathology image processing and analysis routine, which significantly improves the digital pathology image analysis.

A system that determines the quality of a digital microscope slide by analyzing digital slide images based on complexity and spatial frequencies. An example embodiment detailed in the application may provide visual feedback on the whole slide quality by overlaying the image with a color coded “heat map” of local area quality. A user provided with the overlap image may obtain both an absolute quality measurement for the whole image and quickly identity the quality variability within the slide.

A novel and useful method and system of optimized image compression of digital pathology slide images. The optimized image compression mechanism exploits the special color properties of the stained tissue represented by the digital pathology slides and provides an image compression algorithm having improved rate-distortion performance. Optimized color transforms are pre-computed using training sets of pathology slide image scan data for each stain type. The optimized color transforms are used to compress input slide image scans resulting in more efficient image streaming enabling users to review extremely large digital slide scans from any connected location, such as in a hospital, satellite center, home or on a mobile telephone.

By means of the scheme, compatibility with traditional optical microscopic devices is good, repeated development is not required, fast acquisition of an optimum focal plane is achieved, and accuracy of the acquired focal plane is high.

Systems and methods that acquire digital slides and other large images and store these images into commercially available PACS systems using DICOM-standard messaging are provided. A digital slide or other large two-dimensional image is acquired and each separate resolution level of the digital slide or large image is divided into a series of regions that are each identified as a DICOM image. All of the regions at the same resolution in the digital slide or other large image are collectively identified as a DICOM series. A plurality of DICOM series, representing multiple resolution levels in a digital slide are collectively identified and stored as a DICOM study.

An improved diagnostic resolution of digital slide images is obtained by scanning a first digital slide image at diagnostic resolution that is then deconvolved into separate images with one stain per image. The single stain images are then enhanced with image adjustments and/or processed with image analysis algorithms. The resulting single image data sets from the image analysis algorithms can then be stored. Additionally, the resulting enhanced single images can be recombined into a second digital slide image at diagnostic resolution that is also enhanced.

A portion of imagery data is obtained from a digital slide and a protocol of image analysis/diagnostic tasks is performed on the portion of imagery data by a pathologist or an image analysis module. The result of each task (e.g., success or no success) is recorded and a score is determined for the portion of the imagery data. Multiple portions of imagery data from the digital slide are analyzed and scored and the various scores from the multiple portions of imagery data are calculated to determine an overall score for the digital slide. Regions of the digital slide can be scored separately. Multiple rounds of scoring (by different pathologists and/or different image analysis algorithms) may be employed to increase the accuracy of the score for a digital slide or region thereof.
