A hybrid imaging apparatus for imaging an object to be examined located in a sample volume can be operated in an MPI mode and in at least one further imaging mode and comprises a magnet arrangement embodied to generate, in the MPI mode, a magnetic field with a gradient B1 and a field-free region in the sample volume, wherein the magnet arrangement comprises a ring magnet pair with two ring magnets in a Halbach dipole configuration, which are arranged coaxially on a common Z-axis that extends through the sample volume, wherein the ring magnets are arranged so as to be twistable relative to one another about the Z-axis. Consequently, it is possible to generate magnetic fields that meet the requirements of both MRI and MPI such that the hybrid imaging apparatus can be equipped for measurements in various imaging modes, including MPI, MRI and CT.

Methods, systems, and computer readable media are provided for reduced-dose angiography using machine learning (e.g., deep learning). Briefly, techniques described herein may use a neural network trained to conserve/preserve angiographic image quality while reducing the angiographic dose of potentially harmful chemical contrast and/or x-ray radiation. As a result, angiographic anatomy may be extracted from an image at reduced angiographic doses using a deep learning neural network. The reduction in chemical contrast and x-ray dose may be achieved based on operations performed before, during, and/or after angiographic imaging.

Methods for determining systemic biodistribution characteristics of intravitrially administered medicaments. In some embodiments, radiolabeled agents or medicaments, such as I-124 labeled bevacizumab, ranibizumab and aflibercept, was imaged utilizing PET/CT in a non-human primate model, with radioactivity emission measurements made to determine the intravitreal half-lives of each agent and to determine the differences of radioactivity uptake in non-ocular organs.

An operation method of a medical imaging apparatus for capturing an X-ray medical image is provided. The method includes receiving identification information of a user, receiving photographing mode selection information, determining that a photographing mode is an X-ray photographing mode for checking a health condition of an object on the basis of at least one of the identification information of the user and the photographing mode selection information, obtaining identification information of the object, determining an initial photographing position from among a plurality of predetermined photographing positions, and determining a photographing sequence of the plurality of predetermined photographing positions on the basis of the initial photographing position.

A system and method for non-invasive and continuous measurement of cardiac chamber volume and derivative parameters including stroke volume, cardiac output and ejection fraction comprising an ultrawideband radar system having a trans-mitting and receiving antenna for applying ultrawideband radio signals to a target area of a subject's anatomy wherein the receiving antenna collects and transmits signal returns from the target area which are then delivered to a data processing unit, such as an integrated processor or PDA, having software and hardware used to process the signal returns to produce a value for cardiac stroke volume and changes in cardiac stroke volume supporting multiple diagnostic requirements for emergency response and medical personnel whether located in the battlefield, at a disaster site or at a hospital or other treatment facility.p

An imaging system and methods including a gantry defining a bore and an imaging axis extending through the bore, and at least one support member that supports the gantry such that the imaging axis has a generally vertical orientation, where the gantry is displaceable with respect to the at least one support member in a generally vertical direction. The imaging system may be configured to obtain a vertical imaging scan (e.g., a helical x-ray CT scan), of a patient in a weight-bearing position. The gantry may be rotatable between a first position, in which the gantry is supported such that the imaging axis has a generally vertical orientation, and a second position, such that the imaging axis has a generally horizontal orientation. The gantry may be displaceable in a horizontal direction and the system may perform a horizontal scan of a patient or object positioned within the bore.

The present invention provides a system and method for performing a single-scan rest-stress cardiac measurement. In one aspect, the system includes a positron emission tomography (PET) imaging system, a source of a first PET radiotracer for administration to a subject, a source of a second PET radiotracer for administration to a subject, and a processor. The processor has non-transient computer readable media programmed with instructions to obtain PET images of the subject administered with the radiotracer. Furthermore, the computer readable media is programmed with instructions to process the PET images with a non-steady-state, multi-compartment parametric model. An output of the non-steady-state, multi-compartment parametric model is a measure of myocardial blood flow for both a rest state and a stress state of the subject.

A multi-axis imaging system comprising an imaging gantry with an imaging axis extending through a bore of the imaging gantry, a support column that supports the imaging gantry on one side of the gantry in a cantilevered manner, and a base that supports the imaging gantry and the support column. The imaging system including a first drive mechanism that translates the gantry in a vertical direction relative to the support column and the base, a second drive mechanism that rotates the gantry with respect to the support column between a first orientation where the imaging axis of the imaging gantry extends in a vertical direction parallel to the support column and a second orientation where the imaging axis of the gantry extends in a horizontal direction parallel with the base, and a third drive mechanism that translates the support column and the gantry in a horizontal direction along the base.

In certain embodiments, a non-transitory computer-readable storage medium stores a program for execution by one or more processors that includes instructions for receiving a label-generating request for generating a machine-readable image file for an animal-based meat product that corresponds to a particular source animal. The program further includes instructions for accessing, in response to receiving the label-generating request, digital animal records for source animals to identify a digital animal record for the particular source animal. The digital animal records include animal information that includes identification information, location information, and health information for the source animals. The program further includes instructions for generating, based on the animal information of the digital animal record for the particular source animal, a machine-readable image file for the particular source animal that, when decoded, makes available meat facts regarding the particular source animal, and for transmitting the machine-readable image file to a requesting device.
