  • Patent number: 9359641
    Abstract: In a genome sequencing system and methodology, a protocol is provided to achieve precise alignment and accurate registration of an image of a planar array of nanoballs subject to optical analysis. Precise alignment correcting for fractional offsets is achieved by correcting for errors in subperiod x-y offset, scale and rotation by use of minimization techniques and Moiré averaging. In Moiré averaging, magnification is intentionally set so that the pixel period of the imaging element is a noninteger multiple of the site period. Accurate registration is achieved by providing for pre-defined pseudo-random sets of sites, herein deletion or reserved sites, where nanoballs are prevented from attachment to the substrate so that the sites of the array can be used in a pattern matching scheme as registration markers for absolute location identification.

  • Publication number: 20140369579
    Abstract: Systems and methods are provided the autocentering, autofocusing, acquiring, decoding, aligning, analyzing and exchanging among various parties, images, where the images are of arrays of signals associated with ligand-receptor interactions, and more particularly, ligand-receptor interactions where a multitude of receptors are associated with microparticles or microbeads. The beads are encoded to indicate the identity of the receptor attached, and therefore, an assay image and a decoding image are aligned to effect the decoding. The images or data extracted from such images can be exchanged between de-centralized assay locations and a centralized location where the data are analyzed to indicate assay results. Access to data can be restricted to authorized parties in possession of certain coding information, so as to preserve confidentiality.

  • Patent number: 8848997
    Abstract: In a medical image acquisition, and operating method, before acquiring a current planning image data set from a subject, a statistical atlas is generated from multiple planning image data sets using a specific measurement protocol, as a statistical compilation including an average image data set electronically associated with association information that identifies different anatomical entities represented by the statistical compilation. After the current planning image data set is acquired, the stored average image data set is transformed into the current planning image data set, with the association information being accurately associated with the current planning image data set. A diagnostic image acquisition of the subject is then controlled using the association information that is now associated with the current planning image data set.

  • Publication number: 20140270435
    Abstract: Methods, articles and systems that provide imagewise mapping or display of gene expression of a biosample, by contacting the biosample, such as a tissue slice or metacommunity, to a detector which captures material from the biosample and processes the captured material. In one embodiment the detector has an array of one or more capture sites at defined positions on the detector, each site carrying an immobilized capture oligonucleotide and a site-indexing oligonucleotide. The array captures mRNA from the biosample contacted thereto, and the captured mRNA is processed to form a sequenceable amount of amplified captured material which includes the site-indexing oligonucleotide, so that when sequenced, detection of the site-indexing oligonucleotide indicates the original capture location on the array, thereby mapping the sequenced material to its capture location and imaging display of gene expression distribution in the original biosample.

  • Patent number: 8832139
    Abstract: A method for searching a database (206) with stored information using parallel searching of superposition representations of the information. In one approach, the method involves searching a target DNA or RNA genome (16) sequence to determine whether a match is present between a sequence probe and the target. The method includes encoding the target sequence as superpositions of wavefunctions, encoding the probe as one or more wavefunctions, and comparing the encoded target with the encoded probe. The encoding of the target may involve applying a transform (e.g., discrete Fourier transform) to the target sequence to obtain the wavefunctions used to form the one or more superposition representations.
