    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.

    Abstract: The invention provides for a magnetic resonance imaging system (100) comprising a main magnet (104) for generating a main magnetic field within an imaging zone (108). The magnetic resonance imaging system further comprises an RF coil (114) for acquiring magnetic resonance data (164) from the imaging zone, wherein the RF coil comprises multiple RF ports (124, 412, 414, 416, 500, 502, 702, 1004, 1006). The RF coil comprises a switch unit (120) for at least one of the multiple RF ports to individually couple or uncouple the at least one of of the multiple RF ports from the RF coil. The magnetic resonance imaging system further comprises a radio-frequency system (125) for supplying radio-frequency power to each of the multiple RF ports and an RF matching detection system (122) for measuring impedance matching data (166) between the radio-frequency system and the RF coil. Execution of the machine executable instructions causes a processor controlling the magnetic resonance imaging system to measure (200, 300, 302, 304) the impedance matching data using the RF matching detection system; determine (202) switch unit control instructions (168) using the impedance matching data, wherein the switch control instructions contain commands that control the at least one of the multiple RF ports to couple or decouple to impedance match the radio-frequency system to the RF coil; and control (204) the switch unit of the at least one of the multiple RF ports with the switch unit control instructions.
