Patent number: 11669946Abstract: A high-content imaging system includes a stage, a controller, a machine learning system, and an image generator. The controller receives a request including an output imaging configuration and in response the controller: (1) selects a training model associated with the output imaging configuration, (2) determines an input imaging configuration associated with the training model, and (3) configures the high-content imaging system in accordance with the input imaging configuration. The machine learning system is configured using the training model so when the machine learning system is presented with an image acquired using the input imaging configuration, the machine learning system generates an output image in accordance with the output imaging configuration. The image generator generates an image of a sample on the stage and provides the generated image to the machine learning system and, in response, the machine learning system generates an output image in accordance with the output imaging configuration.Type: GrantFiled: October 21, 2020Date of Patent: June 6, 2023Assignee: MOLECULR DEVICES, LLCInventors: Avrum I Cohen, Dihui Hong, Steve Luke, Stephen Rhein

Patent number: 10133053Abstract: A method of generating in-focus images of measurement locations of a sample holder in a microscopy imaging system is provided. A camera array is positioned at a first distance from the sample holder. A first image of a measurement location is acquired using an imaging device disposed on the camera array. A candidate output image associated with the imaging device is developed in accordance with the first image. The camera array is positioned at a second distance from the sample holder and a second image of the measurement location is acquired using the imaging device. A portion of the candidate output image is updated in accordance with a portion of the second image in accordance with a selection criterion. The updated candidate image is transmitted.Type: GrantFiled: April 29, 2014Date of Patent: November 20, 2018Assignee: Molecular Devices, LLCInventor: Avrum I. Cohen

Patent number: 9646194Abstract: A computer-implemented method and system perform efficient and accurate fiber morphology analysis of fiber-containing biological samples. The images of objects comprising fiber and/or branching structure are obtained by camera and/or other imaging devices. Initial tracing seeds are obtained by variable modules. The adaptive threshold method is utilized for identifying tracing seeds candidates by local Principal Component Analysis (PCA) calculation and sorting out the seeds with low and high score. Each single fiber segment of interest is traced repeatedly utilizing PCA fitting calculation, and individual fiber segments are assembled by performing crossover matching calculation.Type: GrantFiled: August 28, 2013Date of Patent: May 9, 2017Assignee: Molecular Devices, LLCInventors: Ting Zhao, Dihui Hong, Avrum I.

Patent number: 8687180Abstract: 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.Type: GrantFiled: June 7, 2012Date of Patent: April 1, 2014Assignee: Molecular Devices, LLCInventor: Avrum I.

Patent number: 8564623Abstract: 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.Type: GrantFiled: December 11, 2009Date of Patent: October 22, 2013Assignee: Molecular Devices, LLCInventors: Avrum I.
