摘要： 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.

摘要： An imaging system, such as a DBT system, capable of providing an operator of the system with information concerning the location, magnitude and direction of motion detected by the system during performance of the scan to enhance image processing. The imaging system provides the motion information to the operator directly in conjunction with the images processed by the imaging system thereby providing the operator with sufficient information for decisions regarding the need for additional images for completing the scan with the imaging system before the patient is discharged, or even before the breast is decompressed.

摘要： The present approach relates to providing image quality feedback to personnel (e.g., a technician) acquiring non-invasive images in real-time or near real-time. By way of example, the proposed approach may automatically assess the quality of images in real-time by evaluating the images for the presence or absence of non-conformities using processor-implemented, rule-based algorithms running partly or completely in parallel to one another. The proposed approach improves the image analysis pipeline by efficiently providing notification of and/or discarding low-quality or unsuitable images or exams after they are taken, such as in within seconds or minutes.

摘要： A method and system for performing a biopsy guided by a 3D image of the object obtained from digital tomosynthesis is performed. The method includes applying a compression paddle to an object; performing a tomosynthesis scan; reconstructing at least a portion of the scan; locating a lesion using a displayed or reprojected marker to determine a location of the lesion; correlating the location of the lesion in the scan to a marker on the compression paddle or tool holder; and proposing a needle entry point of a biopsy tool based off of the correlation so that a needle or penetration device will effectively reach the lesion or target if it is inserted at the proposed entry point. A system for performing a biopsy is further disclosed. In one embodiment, the system comprises: a tomosynthesis imaging apparatus for performing a tomosynthesis scan comprising an x-ray source and an x-ray detector; at least one marker; a compression paddle; a controller; and a display screen for displaying at least a portion of a reproduction of a tomosynthesis scan generated by the imaging apparatus, wherein (i) the at least one marker is displayed on the reproduction, the marker being used to determine a lesion location or target, and (ii) the controller correlates the lesion location or target with the at least one marker and generates a proposed needle entry point based on the correlation so that a needle or penetration device will effectively reach the lesion or target if it is inserted at the proposed entry point.

摘要： Systems and methods of medical imaging includes acquiring a plurality of projection images. A first projection image and a second projection image from the plurality of projection images are selected that are adjacent to a received focal point. A first set of object locations in the first projection image and a second set of object locations in the second projection image are identified that contribute to a pixel of the synthetic projection image. A value for the pixel of the synthetic projection image is calculated from the pixels of the first set of object locations and the pixels of the second set of object locations. The synthetic projection image is created with the calculated value.
