  • METHOD OF PRINTING MULTI-NANOPARTICLES WITH UNIFORM SURFACE USING EVAPORATION DYNAMICS AND SURFACE ENERGY CONTROL
    Publication number: 20230172038
    Abstract: The present disclosure relates to a method of printing multi-nanoparticles using evaporation dynamics and surface energy control, the method includes: a step S1 of forming a pattern on a surface of a substrate by irradiating ultraviolet rays to a portion of the surface through a photomask; a step S2 of coating the substrate with a solution containing nanoparticles; and a step S3 of lowering surface energy of the coated nanoparticles.

  • Apparatus and method of resampling event data for quantitative improvement of pet image
    Patent number: 9794521
    Abstract: Provided are apparatuses and methods of resampling event data for quantitative improvement of a PET image, which acquire a quantitatively-improved new PET image by analyzing a storage format of list data prior to conversion into the PET image and nonparametrically resampling event data from the list data based on the analysis results to improve noise and statistical characteristics thereof. The quantitatively improved new PET image may be acquired by analyzing a storage format of list data constituting the PET image and nonparametrically resampling event data to improve noise and statistical characteristics thereof.
