  • Patent number: 11291737
    Abstract: An aqueous synthesis methodology for the preparation of silica nanoparticles (SNPs), core-shell SNPs having, for example, a size of 2 to 15 nm and narrow size-dispersion with size control below 1 nm, i.e. at the level of a single atomic layer. Different types of dyes, including near infrared (NIR) emitters, can be covalently encapsulated within and brightness can be enhanced via addition of extra silica shells. The surface may be functionalized with polyethylene glycol (PEG) groups and, optionally, specific surface ligands. This aqueous synthesis methodology also enables synthesis of 2 to 15 nm sized fluorescent core and core-shell aluminosilicate nanoparticles (ASNPs) which may also be surface functionalized. Encapsulation efficiency and brightness of highly negatively charged NIR fluorophores is enhanced relative to the corresponding SNPs without aluminum.

  • Patent number: 11257259
    Abstract: For topogram predication from surface data, a sensor captures the outside surface of a patient. A generative adversarial network (GAN) generates the topogram representing an interior organ based on the outside surface of the patient. To further adapt to specific patients, internal landmarks are used in the topogram prediction. The topogram generated by one generator of the GAN may be altered based on landmarks generated by another generator.

  • Publication number: 20220036187
    Abstract: A sample generation method outputs a dummy sample set generated by a trained sample generation network that operates on spliced vectors formed by combining real category feature vectors extracted from real samples with real category label vectors corresponding to the real samples. The trained sample generation network is trained using real samples and dummy samples that are generated by an intermediate sample generation network operating on the spliced vectors. The training includes inputting the real samples and the dummy samples to an intermediate sample discrimination network, performing iterative adversarial training of the intermediate sample generation network and the intermediate sample discrimination network until an iteration stop condition is met. As a result, the dummy sample set output by the trained sample generation network includes dummy samples that are not easily differentiated from real samples and that are already labeled with category information, for accurate use in training classifiers.

  • Publication number: 20210233247
    Abstract: This application relates to a medical image segmentation method, a computer device, and a storage medium. The method includes: obtaining medical image data; obtaining a target object and weakly supervised annotation information of the target object in the medical image data; determining a pseudo segmentation mask for the target object in the medical image data according to the weakly supervised annotation information; and performing mapping on the medical image data by using a preset mapping model based on the pseudo segmentation mask, to obtain a target segmentation result for the target object. Because the medical image data is segmented based on the weakly supervised annotation information, there is no need to annotate information by using much labor during training of the preset mapping model, thereby saving labor costs. The preset mapping model is a model used for mapping the medical image data based on the pseudo segmentation mask.
