  • Publication number: 20210325500
    Abstract: The invention provides for a magnetic resonance imaging system (100, 200) comprising a memory (148) for storing machine executable instructions (150) and pulse sequence commands (152). The pulse sequence commands are configured for acquiring a four dimensional magnetic resonance data set (162) from an imaging region of interest (109). The four dimensional magnetic resonance data set is at least divided into three dimensional data magnetic resonance data sets (400, 402, 404, 406, 408) indexed by a repetitive motion phase of the subject. The three dimensional data magnetic resonance data sets are further at least divided into and indexed by k-space portions (410, 412, 414, 416, 418, 420, 422, 424, 426, 428, 430, 432, 434, 436).

  • Publication number: 20210233644
    Abstract: To obtain feedback on image quality from qualified reviewers, an optically machine readable code (124) (e.g., a QR code or the like) is generated for each acquired medical image and embedded into the image. The embedded code includes information to the identity of the image, the imaging device, authorized reviewers, and authorized recipients of the feedback, as well as a link to a feedback form that can be retrieved by a communication device (38) used by an authorized user. When the embedded code is scanned by the communication device, the code is decoded and the feedback form is retrieved from a server, completed by the reviewer, and transmitted back to the authorized recipients of the feedback.

  • Publication number: 20210182599
    Abstract: Presented are concepts for matching a subject to one or more resources or workflow steps. Once such concept comprises obtaining data associated with a subject, the data comprising, for each of a plurality of parameters, a parameter value relating to the subject. A plurality of data groups for characterising the subject is then generated and a classification process is applied to each data group so as to generate a classification result for each data group. The subject is then matched to one or more resources or workflow steps based on the classification results.

    Abstract: When predicting required component service in an imaging device such as a magnetic resonance (MR) imaging device (12), component parameters such as coil voltage, phase lock lost (PLL) events, etc. are sampled to monitor system components. Voltage samples are filtered according to their temporal proximity to coil plug-in and unplug events to generate a filtered data set that is analyzed by a processor (46) to determine whether to transmit a fault report. A service recommendation is received based on the transmitted report and includes a root cause diagnosis and service recommendation that is output to a user interface (50).
