20230335261 · 2023-10-19 ·

An AI system may be configured to combine a marked area of interest (“AOI”) in a medical image (such as from a user clicking an area of a displayed medical image) with natural language understanding (“NLU”) of a description of the medical image (such as provided by the user via voice input) to determine a more precise region for the AOI. This facilitates more accurate and simplified reporting by using the more precise AOI to determine where to automatically place the description in the report and/or to determine how to best supplement the description with automatically determined anatomical information.

In order to perform denoising on a three-dimensional (3D) spherical measurement of light (such as spherical irradiance probe information or the results of a 3D gonioreflectometry capture), the 3D spherical measurement of light is converted to a two-dimensional (2D) measurement by creating multiple copies of the 3D spherical measurement of light, determining a two-dimensional sub-domain (e.g., a rectangular sub-domain) for each of the multiple copies, and stitching the plurality of two-dimensional sub-domains together in a toroidal configuration. Denoising may then be performed on this 2D measurement via a machine learning implementation or other means. This may result in more accurate 3D spherical light probes that require fewer light measurement samples to generate accurate light measurements.

3D FIDUCIAL FOR PRECISION 3D NAND CHANNEL TILT/SHIFT ANALYSIS

Systems for and methods for generating precise structure reconstruction using slice and view images, are disclosed. An example method comprises, obtaining a slice and view images of a sample that depicts a 3D fiducial and cross-sections of a structure in the sample. The 3D fiducial is configured such that when a layer of material having a uniform thickness is removed from a surface of the sample that includes the 3D fiducial the cross-sectional shape of the 3D fiducial in the new surface is consistent. Relative positions are determined between the 3D fiducial the cross-sections of the structure in individual images. Positional relationships are then determined between the cross-sections of the structure in different images in a common reference frame based on the relative positions.
