  • Publication number: 20210266469
    Abstract: The present disclosure discloses a method and a system for imaging. The method for imaging objects using the system for imaging. The system for imaging comprises a lens. The objects comprise a first object, a second object and a third object located at different positions on a first preset track. The method for imaging comprises: allowing the lens and the first preset track to move relatively in a first predetermined relationship to acquire a clear image of the third object using the system for imaging without focusing, the first predetermined relationship is determined by a focal plane position of the first object and a focal plane position of the second object. The aforementioned method for imaging is high in imaging efficiency and is capable of fast focusing according to the first predetermined relationship even if focus tracking fails so that the blurring of a photographed image due to defocusing is avoided.

  • Publication number: 20210130888
    Abstract: The present disclosure discloses a method, a device and a system for detecting chromosomal aneuploidy. The method comprises: sequencing at least a portion of a nucleic acid in a sample under test to obtain a sequencing result including reads; aligning the reads to a first reference sequence to obtain an alignment result including specific chromosomes to which the reads are mapped; determining, for a first chromosome, the amount of reads mapped to the first chromosome based on the alignment result; and comparing the number of the reads mapped to the first chromosome with the amount of reads in a negative control mapped to the first chromosome to determine the number of the first chromosome. When the method is employed to detect chromosomal aneuploidy, the detection results acquired have relatively high sensitivity and accuracy.

  • Patent number: 10481094
    Abstract: The present disclosure discloses a total internal reflection fluorescence imaging system and a sequencing device. The total internal reflection fluorescence imaging system includes a first imaging system and a second imaging system. The first imaging system includes N separate laser light paths. The second imaging system determines the changes of the height of the sample by means of the differences of the positions at which the second receiving device acquires the second images, and performs automatic compensation according to the changes of the height of the sample, so as to ensure that the sample is always at a focused position. The embodiment can perform light path adjustment of the N separate laser light paths respectively by means of the second imaging system, so as to realize that the N separate laser light paths have the same penetration depth. Therefore no further light path adjustment is required when switching between different light sources, thus saving the time consuming for light path adjustment.
