The present disclosure provides a system and method for magnetic resonance imaging. The method may include obtaining reference information associated with at least two regions of interest (ROIs) of a subject. The method may also include obtaining a plurality of images associated with the at least two ROIs, the plurality of images being determined based on scanning data of the at least two ROIs generated in a single scan performed on the at least two ROIs by an imaging device. The method may further include identifying local images of each of the at least two ROIs from the plurality of images based on the reference information.

Systems and methods for analyzing pathologies utilizing quantitative imaging are presented herein. Advantageously, the systems and methods of the present disclosure utilize a hierarchical analytics framework that identifies and quantify biological properties/analytes from imaging data and then identifies and characterizes one or more pathologies based on the quantified biological properties/analytes. This hierarchical approach of using imaging to examine underlying biology as an intermediary to assessing pathology provides many analytic and processing advantages over systems and methods that are configured to directly determine and characterize pathology from underlying imaging data.

Imaging systems and methods may facilitate positioning an imaging device in a procedure room. A 3D image of a subject may be obtained, where the subject is to have a procedure performed thereon. A view of the 3D image of the subject may be adjusted to a desired view and an associated 2D image reconstruction at the desired view may be obtained. A position for the imaging device that is associated with the desired view of the 3D image of the subject may be identified. Adjusting a view of the 3D image to a desired view and obtaining a 2D image reconstruction may be performed pre-procedure, such that a user may be able to create a list of desired views pre. A user may adjust a physical position of the imaging device to obtain reconstructed 2D preview images at the adjusted physical position of the imaging device prior to capturing an image.

The present invention relates to a computer-implemented method of determining a rotational position of an object in a coordinate system of an x-ray imaging device. An x-ray image is generated of an object to which a Moiré marker for x-ray imaging is attached. Subsequently, the Moiré pattern generated by the Moiré marker is analysed and the rotational position of the marker and hence of the object is determined in a calculative manner. The Moiré marker for x-ray imaging includes a pattern which results in a significantly different appearance when being observed from slightly different perspectives. One embodiment example of the Moiré marker for x-ray imaging consists of two layers with patterns produced by a material that shields x-ray as good as possible like for example lead, surrounded and spaced apart by material that is highly transparent in x-ray like for example air or light plastics. The size of the openings in the pattern shall preferably be small compared to the distance of the two layers such that a small change in orientation of the marker results in a fairly significant change in the structure of the second layer seen through the aperture of the first layer. Multiple structures with different hole sizes and layer distances can be used to have a larger working range while maintaining accuracy.

In one embodiment, a method for generating a three-dimensional (3D) anatomical map, including applying a trained artificial neural network to (a) a set of two-dimensional (2D) fluoroscopic images of a body part of a living subject, and (b) respective first 3D coordinates of the set of 2D fluoroscopic images, yielding second 3D coordinates of the 3D anatomical map, and rendering to a display the 3D anatomical map responsively to the second 3D coordinates.

A radiographic imaging system includes a radiographic detector having a scanning device to obtain patient identifying information. The detector is programmed to display the patient identifying information in human readable form and to access additional information about the patient stored in networked databases.

A radiation imaging system comprises: an image obtaining unit including a radiation detecting unit in which pixels configured to output signals according to a dose of irradiated radiation are arranged in a two-dimensional area, and configured to obtain a radiation image based on the signals; a correction unit configured to correct the radiation image using an input/output characteristic of a pixel, which represents a relationship between the dose of radiation on the pixel and the signal output from the pixel and is obtained using gain data based on a plurality of gain images obtained under different doses; and an updating unit configured to update the gain data using an updating coefficient obtained based on the gain data and a gain image newly obtained by the image obtaining unit.

A method and system for validating a parameter in a medical study are disclosed. The method includes receiving the medical study from a source. A processor determines a first parameter of the medical study to be validated. An imaging protocol is received from a configuration file in an imaging unit. The imaging protocol includes a second parameter corresponding to the first parameter in the medical study. The processor determines if there is a mismatch of the first parameter in the medical study and the second parameter in the imaging protocol. If there is a mismatch, the processor corrects the first parameter in the medical study based on the second parameter in the imaging protocol to validate the medical study.

A high contrast instrument, such as a radiopaque portion, can be captured and/or viewed in an image that is acquired with an imaging system, such as with a fluoroscopic imaging system. A statistical model can be used to assist in identifying a possible or probable location of a target. A user may move the instrument coil to the statistically probable location of the target to, for example, perform a procedure or carry out a task.

A method includes obtaining, at a local imaging system, projection data for an object representing an intensity of radiation detected along a plurality of rays through the object using a first set of imaging parameters; transmitting an image quality dataset related to the obtained projection data to a remote server; generating, via the remote server, localized restoration information based on the received image quality dataset; transferring the localized restoration information from the remote server to the local imaging system; and updating the local imaging system using the localized restoration information.
