  • Patent number: 10753999
    Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a processor and a memory. The memory stores processor-executable instructions that cause the processor to perform an application region scan for acquiring data on an area covering a diaphragm in order to position an application region of a motion detection pulse and a multi-slice scan for acquiring first multi-slice data on an area covering a heart; and acquire a slice image of the heart that is positioned using the first multi-slice data, with application of the motion detection pulse. In acquiring the slice image, when breathing motion of a subject is continuously out of an allowable range for a given period, the processor corrects a position of the application region by calculation using the second multi-slice data acquired by performing the multi-slice scan again and a positional relationship obtained by the application region scan and the multi-slice scan.

  • Patent number: 9504429
    Abstract: An MRI system is provided that includes a physiological sensor used for gating the MRI system and an MRI control terminal wirelessly connected to the sensor. The physiological sensor is used to monitor a physiological parameter of a user, such as pressure pulse, and communicate data regarding the monitored physiological parameter to the MRI control terminal. The MRI control terminal processes the data received from the physiological sensor and determines whether a triggering condition on the data is met. When it is determined that the triggering condition is met, the MRI control terminal initiates the acquisition of a data set. The acquisition of the data set involves initiating a pre-programmed pulse sequence and acquiring RF signals emitted from the patient's tissue as a result of the execution of the pre-programmed pulse sequence.

  • Patent number: 9364166
    Abstract: In order to make it possible to set the optimal breath-holding imaging conditions according to the subject without extension of an imaging time or the sacrifice of image quality, one scan is divided into one or more breath-holding measurements and free-breathing measurements on the basis of the imaging conditions of a breath-holding measurement, which are input and set according to the subject, and a region of the k space measured in the breath-holding measurement is controlled. Preferably, in the breath-holding measurement, low-frequency data of the k space is measured. Moreover, preferably, imaging conditions of the breath-holding measurement include the number of times of breath holding or a breath-holding time, and the operator can set any of these values.

  • Patent number: 9345437
    Abstract: In a method for determining a respiratory phase from a series of measurements of a respiratory position, the respiratory phase is determined by a finite state machine, which processes a current measured respiratory position and at least one previously measured respiratory position, and assigns a current respiratory phase to the current respiratory position. For this purpose, the temporal spacing between two successive measurements of the respiratory position is small in relation to a respiratory cycle. This method allows for a continuous measurement of imaging measurement data to be influenced in a prospective manner in a determined respiratory phase.

  • Patent number: 9301706
    Abstract: A magnetic resonance imaging system uses a first RF coil for acquiring a magnetic resonance signal from a subject, and a device for estimating a cardiac phase of the subject based on the magnetic resonance signal acquired by the first RF coil. The first RF coil, for example, can be an RF coil exclusive to cardiac phase estimation. The magnetic resonance imaging system also uses a second RF coil for acquiring a magnetic resonance signal based on the estimated cardiac phase, and a device for reconstructing a magnetic resonance image of the subject based on the magnetic resonance signal acquired by the second RF coil. Thus, MRA can be performed by estimating a cardiac phase.

  • Patent number: 9261575
    Abstract: For generating a three-dimensional magnetic resonance image of a respirating examination subject, the respiration of the examination subject is divided into a number of predefined clusters. Based on a measured respiratory position of the examination subject, one of these clusters is selected. The scanned k-space range is divided into a number of data acquisition shots which, by means of a particular k-space trajectory, each fill a number of k-space lines. The different shots are acquired for the different clusters until all shots of the measurement data set are assigned together to at least two adjacent clusters. The magnetic resonance image is reconstructed from those shots that are assigned to at least two adjacent clusters.
