4 results about "High signal intensity" patented technology

An image processing method includes: a step of creating, by a blood vessel mask creation unit, a blood vessel mask image by removing a punctate low signal intensity, removing a linear low signal intensity, extracting the linear low signal intensity, removing a punctate high signal intensity, removing a linear high signal intensity, and extracting the linear high signal intensity from an image obtained from a magnetic resonance signal intensity in which a region corresponding to a blood vessel is enhanced with respect to an MRI image; and a step of generating, by a mask processing unit, an image in which a blood vessel structure is removed using the blood vessel mask image from a phase difference enhanced image created from the MRI image.

The invention discloses a space metabonomics analysis method and application thereof, relates to the technical field of metabonomics analysis, and solves the problem that an analysis result of an existing conventional space metabonomics analysis method is not accurate enough. To-be-analyzed biological tissue samples are taken and divided into groups; preparing all groups of samples into slices, adsorbing the slices on the same glass slide, carrying out mass spectrum imaging detection, and synchronously collecting metabolite spatial distribution signals and mass spectrum intensity data of all the samples; the method comprises the following steps: preprocessing collected original data, identifying the distribution condition of known exogenous components in a medicine in a tissue slice, and delimiting a region with high signal intensity as a region of interest; randomly selecting a plurality of pixel points in the region of interest of each sample; and integrating the mass spectrum data corresponding to the pixel points selected from all the parallel samples in the same group, and sequentially carrying out PCA, OPLS-DA, differential metabolite screening and KEGG pathway enrichment analysis. The method can be applied to research on the hepatotoxicity of the polygonum multiflorum and the prepared polygonum multiflorum.

A photoacoustic spectroscopy system is provided, comprising an acoustic cell, an electromagnetic radiation unit, and a resonant transducer unit. The acoustic cell includes a resonant cavity supporting a first resonant mode having a first resonant frequency, and to which a sample fluid can be supplied. The resonant transducer supports a second resonant mode having a second resonant frequency and is functionally connected to the resonant cavity. The first and second resonant modes are configured to be coupled in a significant coupling region, and the adjustment of the first and second resonant modes is configured to result in an increase in signal intensity or signal-to-noise ratio.

The invention relates to the field of quarantine detection, and discloses a high-robustness and high-signal-intensity digital immunodetection kit and method.The kit comprises an inert nucleic acid sealing agent and a nucleic acid embedding dye; the inert nucleic acid sealing agent is coated on the surface of the solid phase carrier or contained in the rolling circle amplification reaction liquid; the nucleic acid intercalation dye is contained in the rolling circle amplification reaction liquid, and the emission spectrum of the nucleic acid intercalation dye is compatible with the emission spectrum of the sequence specific probe with the fluorescence label. Strong and uniform signals can be converted into accurate quantitative results only by depending on accurate single magnetic bead counting. And meanwhile, the flow design difficulty is also reduced by clear signal separation, so that the single magnetic bead analysis in the presence of the sealing agent is simpler and more reliable. Through the combined action of the two, the kit is especially suitable for stable and accurate quantification of the extremely low abundance protein marker in a complex clinical sample.
