System and methods for reconstructing medical images using deep neural networks and recursive decimation of measurement data
Methods and systems are provided for reconstructing images from measurement data using one or more deep neural networks according to a decimation strategy. In one embodiment, a method for reconstructing an image using measurement data comprises, receiving measurement data acquired by an imaging device, selecting a decimation strategy, producing a reconstructed image from the measurement data using the decimation strategy and one or more deep neural networks, and displaying the reconstructed image via a display device. By decimating measurement data to form one or more decimated measurement data arrays, a computational complexity of mapping the measurement data to image data may be reduced from O(N.sup.4), where N is the size of the measurement data, to O(M.sup.4), where M is the size of an individual decimated measurement data array, wherein M<N.
IMAGING SYSTEMS AND METHODS
An imaging method may include obtaining imaging data associated with a region of interest (ROI) of an object. The imaging data may correspond to a plurality of time-series images of the ROI. The imaging method may also include determining, based on the imaging data, a data set including a spatial basis and one or more temporal bases. The spatial basis may include spatial information of the imaging data. The one or more temporal bases may include temporal information of the imaging data. The imaging method may also include storing, in a storage medium, the spatial basis and the one or more temporal bases.

An information processing apparatus performs coordinate calibration between a two-dimensional (2D) coordinate system and a three-dimensional (3D) coordinate system. The apparatus includes a 2D camera interface, a 3D camera interface, and a processor. The processor is configured to receive, from the 2D camera interface, first 2D image data of a flat plate at a first position and second 2D image data of the flat plate at a second position different from the first position, receive, from the 3D camera interface, first 3D coordinate information of the flat plate at the first position and second 3D coordinate information of the flat plate at the second position, and generate a transformation matrix for transforming a 3D coordinate value to a 2D coordinate value, based on the first and second 2D image data and the first and second 3D coordinate information.
Multimodality 2D to 3D imaging navigation
A system and method for the detection of ROIs in images obtained of a breast or other tissue of a patient significantly improves the speed and precision/accuracy of navigation between multimodality 2D and 3D images. In the system and method, images of the tissue are obtained in a DBT acquisition to generate a synthetic 2D image of the imaged tissue and in a 3D, e.g., ultrasound, image acquisition. The 2D image generation process creates a synthetic 2D image that embed a navigation map correlating pixels in the 2D images to sections of the 3D ultrasound volume, such as via a registration between the 3D ultrasound volume and a 3D volume created using the DBT image data. When a synthetic 2D image is reviewed, an ROI on the 2D image is selected and the system will additionally present the user with the section of the 3D volume containing that ROI.
