Patent number: 11501545Abstract: Automation of microscopic pathological diagnosis relies on digital image quality, which, in turn, affects the rates of false positive and negative cellular objects designated as abnormalities. Cytogenetic biodosimetry is a genotoxic assay that detects dicentric chromosomes (DCs) arising from exposure to ionizing radiation. The frequency of DCs is related to radiation dose received, so the inferred radiation dose depends on the accuracy of DC detection. To improve this accuracy, image segmentation methods are used to rank high quality cytogenetic images and eliminate suboptimal metaphase cell data in a sample based on novel quality measures. When sufficient numbers of high quality images are found, the microscope system is directed to terminate metaphase image collection for a sample. The International Atomic Energy Agency recommends at least 500 images be used to estimate radiation dose, however often many more images are collected in order to select the metaphase cells with good morphology for analysis.Type: GrantFiled: December 29, 2020Date of Patent: November 15, 2022Assignee: CytoGnomix Inc.Inventors: Peter Keith Rogan, Yanxin Li, Jin Liu

Patent number: 10929641Abstract: An automated microscope system is described that detects dicentric chromosomes (DCs) in metaphase cells arising from exposure to ionizing radiation. The radiation dose depends on the accuracy of DC detection. Accuracy is increased using image segmentation methods are used to rank high quality cytogenetic images and eliminate suboptimal metaphase cell data in a sample based on novel quality measures. When a sufficient number of high quality images are detected, the microscope system is directed to terminate metaphase image collection for a sample. The microscope system integrates image selection procedures that control an automated digitally controlled microscope with the analysis of acquired metaphase cell images to accurately determine radiation dose. Early termination of image acquisition reduces sample processing time without compromising accuracy. This approach constitutes a reliable and scalable solution that will be essential for analysis of large numbers of potentially exposed individuals.Type: GrantFiled: August 7, 2018Date of Patent: February 23, 2021Assignee: CytoGnomix Inc.Inventors: Peter Keith Rogan, Yanxin Li, Jin Liu

Patent number: 9491398Abstract: A method and system for detecting and processing a series of video frames includes receiving the series of video frames, determining whether the video frames are associated with a recognized non-video source, and depending on the determination, processing the video frames using a variety of techniques. A system may detect whether each video frame is a repeat frame or a new original frame, keep the new original frames, discard the repeat frames, and then adjust one or more timestamps associated with the new original frames so as to conform to an intermediate frame rate. The frame indexes and timestamps associated with the new original frames are stored in a FIFO or buffer. The system can interpolate video frames using the stored timestamps, and output a series of video frames. The output video stream is delivered at any frame rate and can include original video frames and interpolated video frames.Type: GrantFiled: June 28, 2013Date of Patent: November 8, 2016Assignee: PIXELWORKS, INC.Inventors: Yongmin Hou, Yanxin Li, Jian Zhou, Miao Sima, Neil D.
