Patent number: 11580677Abstract: Methods and systems for deep learning based image reconstruction are disclosed herein. An example method includes receiving a set of imaging projections data, identifying a voxel to reconstruct, receiving a trained regression model, and reconstructing the voxel. The voxel is reconstructed by: projecting the voxel on each imaging projection in the set of imaging projections according to an acquisition geometry, extracting adjacent pixels around each projected voxel, feeding the regression model with the extracted adjacent pixel data to produce a reconstructed value of the voxel, and repeating the reconstruction for each voxel to be reconstructed to produce a reconstructed image.Type: GrantFiled: March 2, 2020Date of Patent: February 14, 2023Assignee: General Electric CompanyInventors: Giovanni John Jacques Palma, Razvan Iordache

Patent number: 11514624Abstract: Methods and systems are provided for reconstruction error assessment for an interventional tool utilized in an image guided interventional procedure. In one example, an error model based on a target lesion position within a tissue, one or more interventional tool parameters, and imaging system parameters may be utilized to estimate an expected reconstruction error for the interventional tool. In another example, when the interventional tool is within the tissue, the expected reconstruction error may be utilized along with observed tool shape and size to infer an actual tool position and shape within the tissue.Type: GrantFiled: March 16, 2020Date of Patent: November 29, 2022Assignee: GE Precision Healthcare LLCInventors: Charlotte Delmas, Jorge Corsino Espino, Razvan Iordache, Serge Calisti, Laurence Vancamberg

Patent number: 10755454Abstract: An imaging system, such as a DBT system, is provided that is capable of providing processing of an image from initial generation/reconstruction of the image through the review of the image by a radiologist or other practitioner that produces images optimized for the particular task/process performed using the images. The task/review that the radiologist is performing on the processed or reconstructed image can be modeled with regard to the initial generation of the processed or reconstructed images from the raw images or the model considerations can be retroactively applied and back propagated through the image processing performed by the system. These modeling considerations that can take the form of an indicator of clinical performance is/are used by the system to optimize and produce an image(s) that best represents the items in the image necessary for an accurate diagnosis of the patient when reviewed by the radiologist.Type: GrantFiled: December 22, 2017Date of Patent: August 25, 2020Assignee: General Electric CompanyInventors: Giovanni Palma, Razvan Iordache, Serge Muller, Zhijin Li, Ann-Katherine Carton
