Imaging Blood Cells
This document describes methods, systems and computer program products directed to imaging blood cells. The subject matter described in this document can be embodied in a method of classifying white blood cells (WBCs) in a biological sample on a substrate. The method includes acquiring, by an image acquisition device, a plurality of images of a first location on the substrate, and classifying, by a processor, objects in the plurality of images into WBC classification groups. The method also includes identifying, by a processor, objects from at least some classification groups, as unclassified objects, and displaying, on a user interface, the unclassified objects and at least some of the classified objects.
Quality Control of Automated Whole-slide Analyses
The subject disclosure presents systems and methods for automatically selecting meaningful regions on a whole-slide image and performing quality control on the resulting collection of FOVs. Density maps may be generated quantifying the local density of detection results. The heat maps as well as combinations of maps (such as a local sum, ratio, etc.) may be provided as input into an automated FOV selection operation. The selection operation may select regions of each heat map that represent extreme and average representative regions, based on one or more rules. One or more rules may be defined in order to generate the list of candidate FOVs. The rules may generally be formulated such that FOVs chosen for quality control are the ones that require the most scrutiny and will benefit the most from an assessment by an expert observer.
System and Method for Segmentation of Three-Dimensional Microscope Images
A system and method to segment an image captured from an image capture device of a high content imaging system includes an image acquisition module that receives the image captured by the image capture device. A coarse object detection module develops a coarse segmented image, wherein each pixel of the coarse segmented image is associated with a corresponding pixel in the captured image and is identified as one of an object pixel and a background pixel. A marker identification module selects at least one marker pixel from the pixels of the coarse segmented image, wherein each marker pixel is one of a contiguous group of object pixels in the coarse segmented image that is furthest from a background pixel relative to neighboring pixels of the group. An object splitting module that comprises a plurality of processors operating in parallel that associates each object pixel of the coarse segmented image with a marker pixel, wherein a distance based metric between the object pixel and the marker pixel is less than the distance based metric between the object pixel and any other marker pixel in the coarse segmented image.
METHODS FOR QUANTITATIVE ASSESSMENT OF MUSCLE FIBERS IN MUSCULAR DYSTROPHY
The disclosure concerns a method for assessing muscular dystrophy-linked protein expression in muscle fibers using digital image analysis of tissue. The method relates to assessing disease severity in individuals with muscular dystrophy. Muscle tissue samples are obtained from patients submitted for evaluation and processed to produce tissue sections mounted on glass slides which have been stained for a muscular dystrophy-linked protein. Digital images of the stained tissue sections are generated and analyzed by applying an algorithm process implemented by a computer to the images. The algorithm process extracts the morphometric and staining features of the muscular dystrophy-linked protein staining in the tissue, and parameters relating to these features are used to score the disease status for each patient submitted for evaluation. The score of disease status is ultimately used to infer disease severity, monitor the efficacy of a therapeutic approach, or select patients as candidates for a therapeutic approach.
ADAPTIVE SENSING BASED ON DEPTH
A microscope for adaptive sensing may comprise an illumination assembly, an image capture device configured to collect light from a sample illuminated by the assembly, and a processor. The processor may be configured to execute instructions which cause the microscope to capture, using the image capture device, an initial image set of the sample, identify, in response to the initial image set, an attribute of the sample, determine, in response to identifying the attribute, a three-dimensional (3D) process for sensing the sample, and generate, using the determined 3D process, an output image set comprising more than one focal plane. Various other methods, systems, and computer-readable media are also disclosed.
PHENOTYPING TUMOR INFILTRATING LYMPHOCYTES ON HEMATOXYLIN AND EOSIN (H&E) STAINED TISSUE IMAGES TO PREDICT RECURRENCE IN LUNG CANCER
The present disclosure relates to an apparatus including one or more processors configured to receive a digitized image of a region of tissue demonstrating a disease, and containing cellular structures represented in the digitized image, each of the cellular structures being associated with a cell category of a plurality of cell categories; select a cellular structure of the cellular structures based on the cell category for the cellular structure; for the cellular structure selected, compute a set of contextual features; assign, based on the set of contextual features, the cellular structure to at least one cluster of a plurality of clusters; compute cluster features, the cluster features describing characteristics of the at least one cluster of the plurality of clusters; and generate a prediction that describes a pathologic or phenotypic state of the disease based, at least in part, on the cluster features and/or the set of contextual features.
CULTURING ASSISTANCE DEVICE, CULTURING ASSISTANCE METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM
There is provided a culturing assistance device including: a memory which stores a program; and a processor which executes the program, wherein the processor executes the program to implement: acquiring a plurality of captured images in which cells are captured in time series; calculating a probability that a state of the cells shown in the acquired image is a certain state; reading predetermined state change rule information which is stored in a storage unit and indicates a relationship among a plurality of states of the cells in the time-series; and determining the state of the cell based on the calculated probability and the read state change rule information.
