Patent number: 11182913Abstract: Presented herein are systems and methods for registering one or more images of one or more subjects based on the automated generation of artificial landmarks. An artificial landmark is a point within an image that is associated with a specific physical location of the imaged region. The artificial landmarks are generated in an automated and robust fashion along the bones of a subject's skeleton that are represented in the image (e.g. graphically). The automatically generated artificial landmarks are used to correct distortion in a single image or to correct distortion in and/or co-register multiple images of a series of images (e.g. recorded at different time points). The artificial landmark generation approach described herein thereby facilitates analysis of images used, for example, for monitoring the progression of diseases such as pulmonary diseases.Type: GrantFiled: June 15, 2018Date of Patent: November 23, 2021Assignees: PerkinElmer Cellular Technologies Germany GmbH, PerkinElmer Health Sciences, Inc.Inventors: Peet Kask, Jeffrey Meganck

Patent number: 11153499Abstract: Presented herein are systems and methods that provide for fast image acquisition with a CCD camera for tomographic imaging by synchronizing illumination with the image acquisition sequence of the CCD camera. The systems and methods described herein allow images to be acquired with a CCD camera using short image acquisition times that would otherwise result in the introduction of severe artifacts into the acquired images. This unique capability is achieved by selectively illuminating the one or more object(s) to be imaged during specific phases of the CCD camera that are used to acquire an image. Reducing the time required to acquire artifact-free images in this manner allows for rapid imaging with a CCD camera. This capability is of particular relevance to tomographic imaging approaches, in which multiple images of one or more objects are acquired and used to produce a single tomographic image.Type: GrantFiled: October 17, 2018Date of Patent: October 19, 2021Assignee: PerkinElmer Health Sciences, Inc.Inventors: Ali Behrooz, William Hurley, Ilias Faqir

Patent number: 11141064Abstract: Presented herein are systems and methods for tomographic imaging that provide for rapid illumination of multiple excitation locations across a large field of view by one or more beams of excitation light from one or more excitation sources. The approaches described herein utilize a galvanometer optical scanner to scan a beam of excitation light through a plurality of locations across a scan region corresponding to the field of view to be imaged. In certain embodiments, the systems and methods described herein utilize beams of excitation light with specifically tailored shapes to maintain small spot sizes across the large scan region. The ability to scan over a large region while still maintaining small spot sizes provided by the approaches described herein allows for accurate, high-resolution tomographic imaging of large or multiple subjects, thereby expanding the capabilities of tomographic imaging systems.Type: GrantFiled: July 19, 2017Date of Patent: October 12, 2021Assignee: PerkinElmer Health Sciences, Inc.Inventors: William Hurley, Ali Behrooz, Michael Meltzer, Andrew Wilson

Patent number: 11069331Abstract: A noise reduction filter for data signals is implemented using two orthogonal coordinates comprising intensity and differential intensity values generated from sampling and sorting the data signals. A weighting function is used to amplify or reduce different portions of a data set distribution generated using the intensity and differential intensity values. The weighting function may also include scalar constants to further enhance the capability of the noise reduction filter. The noise reduction filter can be used to reduce the noise components or increase the useful signal components of a noisy data signal, thereby increasing the signal-to-noise ratio, and also increasing spectral resolution. The noise reduction filter can also be used in special cases where the intensity and frequency spectra of the noisy data signal are overlapping. The noise reduction filter may be used in various applications including spectroscopy and image processing, among others.Type: GrantFiled: February 14, 2019Date of Patent: July 20, 2021Assignee: PerkinElmer Health Sciences, Inc.Inventor: V.

Patent number: 11016108Abstract: Microfluidic cartridges or devices for serum separation and blood cross-match analysis are provided. The devices may include a serum separation subcircuit alone or in combination with a solute mixing subcircuit. The serum separation subcircuit promotes on-cartridge clotting of a blood sample and manipulates the flow of the separated serum sample for subsequent cross-match analysis with a second blood sample, for example. The solute mixing subcircuit includes at least two intake channels, one for a whole blood sample from, for example, a blood donor and the other for the separated serum sample from, for example, a transfusion recipient. The solute mixing subcircuit further includes a serpentine mixing channel conjoined to a downstream channel. Under vacuum generated by a conjoined finger pump, the two input streams fill the serpentine mixing and downstream channels due to capillary action, enabling visualization of an agglutination reaction.Type: GrantFiled: June 27, 2019Date of Patent: May 25, 2021Assignee: PERKINELMER HEALTH SCIENCES, INC.Inventors: Andrew W.
