Abstract:
Methods and systems for counting nuclei for cells in a cell-containing sample are disclosed, such as carried out on a computer. The methods comprise: receiving a raw image of the cell-containing sample; transforming the raw image into a segmented image comprising one or more nuclei clusters. The methods further comprise: for each of the one or more nuclei clusters, obtaining a convex hull of the nuclei cluster; locating any indentations on the nuclei cluster by comparing the nuclei cluster to the convex hull of the nuclei cluster; calculating a first nuclei count based on a tally of the indentations; and assigning the nuclei cluster to a cell among the plurality of cells. The methods further comprise: calculating a second nuclei count for each cell by totaling the first nuclei counts of its constituent nuclei clusters; and presenting a result based on the second nuclei count for at least one of the plurality of cells.
Abstract:
A system and method of determining a focal position for an objective positioned at a measurement location of a sample holder in a microscopy imaging system are provided. The objective is moved to a position relative to the sample holder that corresponds to a distance between the objective and the sample holder. The sample holder has a conditioned upper surface. A focusing light beam is projected onto the sample holder when the objective is located at the position, and the objective focuses the focusing light beam on the sample holder. A reflected light beam resulting from reflection of the focusing light beam off the conditioned upper surface is observed. The focal position for the objective is determined based on the reflected light beam such that the objective produces an in focus image of a microscopy sample when the objective is located at the focal position.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing an integrated data visualization interface for multi-dimensional microscopy image and measurement data are disclosed. The integrated data visualization interface utilizes the known dimensional relational relationships between the images to automatically provide synchronized and coordinated visualization and manipulations across multiple related images and measurement data in multiple dataset viewer components (e.g., image grids, browsable image strips, tables, and graphs). Other features of the dataset viewer components are also disclosed.
