  • Patent number: 11989833
    Abstract: The present teaching relates to method, system, medium, and implementations for fusing a 3D virtual model with a 2D image associated with an organ of a patient. A key-pose is determined as an approximate position and orientation of a medical instrument with respect to the patient's organ. Based on the key-pose, an overlay is generated on a 2D image of the patient's organ, acquired by the medical instrument, by projecting the 3D virtual model on to the 2D image. A pair of feature points includes a 2D feature point from the 2D image and a corresponding 3D feature point from the 3D virtual model. The 3D coordinate of the 3D feature point is determined based on the 2D coordinate of the 2D feature point. The depth of the 3D coordinate is on a line of sight of the 2D feature point and is determined so that the projection of the 3D virtual model from the depth creates an overlay approximately matching the organ observed in the 2D image.

  • Patent number: 11978751
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.
