Abstract: A method for magnetic resonance imaging (MRI) includes determining a Partial Fourier (PF) factor and an acceleration factor for acquiring k-space data from a subject. The method also includes acquiring a set of k-space data from the subject using the PF factor along with an under-sampling technique, wherein the under-sampling technique is dependent on the acceleration factor. The image of the subject is reconstructed by processing the set of k-space data using a deep learning (DL) network.

Abstract: Systems/techniques that facilitate machine learning generation of low-noise and high structural conspicuity images are provided. In various embodiments, a system can access an image and can apply at least one of image denoising or image resolution enhancement to the image, thereby yielding a first intermediary image. In various instances, the system can generate, via execution of a plurality of machine learning models, a plurality of second intermediary images based on the first intermediary image, wherein a given machine learning model in the plurality of machine learning models receives as input the first intermediary image, wherein the given machine learning model produces as output a given second intermediary image in the plurality of second intermediary images, and wherein the given second intermediary image represents a kernel-transformed version of the first intermediary image. In various cases, the system can generate a blended image based on the plurality of second intermediary images.

Abstract: Various methods and systems are provided for an x-ray imaging system. In one example, a method for the system includes, responsive to operation of the x-ray imaging system in an automated mode, generating a difference image from a first image and a second image. The difference image is displayed at a display device to allow motion outside of a region of interest (ROI) to be detected based on analysis of the difference image. Further, the difference image is displayed before a contrast agent reaches the ROI.

Abstract: A computer-implemented method for determining a flow rate for a given vessel includes obtaining, via a processor, dynamic three-dimensional (3D) images of a subject utilizing nuclear medicine imaging. The method also includes obtaining, via the processor, injection parameters for a radiotracer bolus injected into the subject via an automated injector. The method further includes generating, via the processor, time activity curves (TACs) for the radiotracer bolus from the 3D images. The method even further includes estimating, via the processor, the flow rate for the given vessel based on a morphology of the one or more TACs and the injection parameters.

Abstract: Various methods and systems are provided for agnostic transmission of radiation information data. In one example, a radiation manual entry tool (RMET) includes a worklist access component series configured to receive via a network a first user input requesting access to a modality worklist, transform the first user input from a first format to a second format, transmit the first user input via the network, and receive a requested modality worklist via the network. The RMET further includes a data submission component series configured to receive via the network a second user input including radiation dose information manually entered into the requested modality worklist, transform the second user input from the first format to the second format, transmit the second user input via the network, and receive a message via the network confirming receipt of the manually entered radiation dose information for a scheduled procedure of the requested modality worklist.
