    Abstract: The invention relates to an apparatus configured to display an aortic valve image and an indicator when the aortic valve is in its open-state and/or when the valve is in its closed-state. The indicator is supposed to be in an overlay to the image of the aortic valve, such that a physician can see on the same display image the information needed to advance a guide wire or catheter through the aortic valve of a heart. This may prevent damaging ensures not to damage the aortic valve. The physician receives the relevant information, when the aortic valve is in its open-state and thus being in a state to be passed by the catheter. The information, whether the aortic valve is in its open-state or in its closed-state, corresponds to the systolic phase and the distal phase of the heart, respectively. The information, when the heart is in its systolic phase and when it is in the diastolic phase may be extracted from an ECG measurement.

  • Patent number: 11226387
    Abstract: Provided is a new scheme for applying a CS technology in a technology for imaging a target tissue based on a difference from a reference image or a control image. In this way, an imaging time is shortened. A measurement unit of an MRI apparatus executes a first imaging sequence and a second imaging sequence having different contrasts for a target, and measures a nuclear magnetic resonance signal from a subject in each of the imaging sequences. In the second imaging sequence, under-sampling is performed, and a nuclear magnetic resonance signal having a small number of samples is measured. The image processing unit restores measurement data including a nuclear magnetic resonance signal obtained by under-sampling using compressed sensing. At this time, data restoration including a term for minimizing an L1 norm is performed for a difference image between an image obtained by execution of the first imaging sequence and an image obtained by execution of the second imaging sequence.

The RR-VFA method assumes the existence of a “reference region” that is distributed throughout the volume of interest and is well characterized by a known T1 relaxation time. In particular, fat is generally selected as the reference region due to its distribution in the body. B1+ inhomogeneity is estimated in the fat tissue and interpolated over the entire volume of interest, thus eliminating the need for an additional scan.

  • Patent number: 10687785
    Abstract: Systems and methods for detecting electromechanical wave propagation within a body structure of a patient in a series of image frames representing movement the body structure are provided. Image data is acquired comprising a series of image frames corresponding to the movement of a body structure. A correlation calculation is performed on the image frames to generate a displacement map representing the relative displacement between the first and second image frames. A video is generated comprising a series of displacement maps. The parameters of movement of the body structure are detected by analysis of the displacement maps. The image acquisition can detect the movement of the body structure without inducing such movement.

  • Patent number: 10667760
    Abstract: In a method and magnetic resonance (MR) apparatus for heart diffusion imaging, when an ECG trigger signal by a computer that operates an MR scanner, the MR scanner is operated to acquire a navigator echo before a stimulated echo sequence, in order to detect diaphragm position information. When the first diaphragm position information is not located in an acquisition window, the stimulated echo sequence is not executed, and the computer waits to receive the next ECG trigger signal. The detection time of the navigator echo after the stimulated echo sequence as well as the acquisition time of the stimulated echo sequence, are thus eliminated when the first diaphragm position information does not meet requirements, so can significantly reduce scanning time, and increase the image SNR.

  • Patent number: 10649044
    Abstract: A method of hyperpolarisation of nuclear spins in one or more particle(s) moving relatively to a polarisation structure, wherein a polarisation of electron spins in the polarisation structure is transferred to the nuclear spins in the particle(s), wherein for one or more of the moving particle(s) within 20 nm from a surface of the polarisation structure, the correlation time of the interaction with the nearest polarisation structure electron spin due to the molecular motion is larger than the inverse of the nuclear Larmor frequency; the electron spins in the polarisation structure are polarised above thermal equilibrium; and the polarisation transfer is performed resonantly.

  • Patent number: 10617821
    Abstract: It may desirable to monitor or control a pump remotely. For example, the pump may be positioned near the patient, with remote control or monitoring of the pump occurring in a control room. In one exemplary embodiment, the pump is used in an MRI environment. In another exemplary embodiment, the pump is used in a hyperbaric chamber. The pump may monitor one or more physiological parameters and transmit them to the remote. The pump may also transmit information relating to the pump's operation. The pump may send the device and/or physiological data using one or more packets. The packets may consist of low priority sequential packets and high-priority asynchronous packets. The high-priority packets may enable the real-time monitoring of a patient's heart beat or other physiological parameter.

  • Patent number: 10543312
    Abstract: A fluid delivery system includes a pressurizing mechanism. The pressurizing mechanism includes: a substantially cylindrical body having a movable member positioned therein that divides the body into a first chamber and a second chamber; a plunger rod connected to a first side of the movable member and extending through a substantially closed first end of the body; and an elongated member connected to a second side of the movable member and extending through a substantially closed second end of the body. The plunger rod configured to operatively engage a fluid container. Fluid is dispensed from the fluid container by forming a vacuum within at least the first chamber by moving the movable member toward the second end of the body, allowing atmospheric pressure to enter the second chamber, and actuating the pressurizing mechanism to cause the moving member to move towards the first end of the body.

  • Patent number: 10517556
    Abstract: A method for increasing the temporal fidelity, increasing the temporal sampling density, and/or reducing the temporal noise of a series of image frames obtained with a medical imaging system is provided. The image frames are acquired with the medical imaging system. The medical imaging system may be, for example, an x-ray C-arm imaging system. A window function that is representative of a temporal fidelity window is selected and used to temporally deconvolve the image frames using a minimization technique. A temporal sampling density may also be selected and used in the temporal deconvolution. The resultant deconvolved image frames have a higher temporal fidelity to a time-varying image contrast depicted in the acquired image frames, and may also have an increased temporal sampling density and/or reduced temporal noise.

  • Patent number: 10492710
    Abstract: The present disclosure relates to a method for performing phosphorous-31 spectroscopic magnetic resonance fingerprinting (MRF). The method comprises performing a pulse sequence using a series of varied sequence blocks to a volume in a subject where the volume contains phosphate metabolites. A series of signal evolutions are acquired from the volume in the subject to form MRF data. The MRF data is then compared to simulated MRF signal to determine parameters associated with phosphate metabolites and the chemical exchange rates between these metabolites. These parameters and exchange rates can be used in diagnosing a metabolic disorder in a subject.
