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, 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). The magnetic resonance imaging system further comprises a processor (144) for controlling the magnetic resonance imaging system. Execution of the machine executable instructions causes the processor during a first operational portion (310) to iteratively: receive (300) a motion signal (156) descriptive of the repetitive motion phase; acquire (302) an initial k-space portion using the pulse sequence commands, wherein the initial k-space portion is selected from the k-space portions; store (304) the motion signal and the initial k-space portion in a buffer (158) for each iteration of the first operational portion; at least partially construct (306) a motion phase mapping (160) between the motion signal and the repetitive motion phase; and continue (308) the first operational portion until the motion phase mapping is complete. Execution of the machine executable instructions causes the processor to assign (312) the initial k-space portion for each iteration of the first operational portion in the temporary buffer to the four dimensional magnetic resonance data set using the motion phase mapping. Execution of the machine executable instructions causes the processor during a second operational portion (332) to iteratively: receive (314) the motion signal; determine (316) a predicted next motion phase using the motion signal and the motion phase mapping; select (318) a subsequent k-space portion (154) from the k-space portions of the four dimensional magnetic resonance data set using the predicted next motion phase; acquire (320) the subsequent k-space portion using the pulse sequence commands; rereceive (322) the motion signal; determine (324) a current motion phase using the re-received motion signal and the motion phase mapping; assign (326) the subsequent k-space portion to the four dimensional magnetic resonance data set using the current motion phase; and repeat (328) the second operational portion until the k-space portions for each repetitive motion phase has been assigned.

Abstract: A medical apparatus (300, 400, 500) includes a magnetic resonance imaging system (306); magnetic compensation coils (334, 335) for compensating for magnetic inhomogeneities within the imaging zone; a gantry (308) operable for rotating about the imaging zone; a position sensor (312) for measuring the angular position and the angular velocity of the gantry; at least one magnetic field distorting component (310, 510, 512) in the gantry; and a memory (362) storing machine executable instructions (380, 382, 410, 530, 532) and field correction data (372). The instructions cause a processor to: receive (100, 200) the position and angular velocity data from the position sensor; determine (102, 202) coil control commands (374) for controlling the magnetic compensation coils using the field correction data, the position data and the angular velocity data; control (104, 204) the magnetic compensation coils to compensate for magnetic inhomogeneities within the imaging zone using the coil control commands; and acquire (106, 212) the magnetic resonance data.

Abstract: A combined magnetic resonance (MR) and radiation therapy system includes a bore-type magnet with a magnet radiation translucent region which allows radiation beams to travel radially through the magnet and a split-type gradient coil includes a gradient coil radiation translucent region aligned to the magnet radiation translucent region. A radiation source, disposed laterally to the magnet, administers a radiation dose through the magnet and gradient coil radiation translucent regions to an examination region. A dosage unit determines the actual radiation dose delivered to each voxel of a target volume and at least one non-target volume based on a pre-treatment, intra-treatment, and/or post-treatment image representation of the target volume and the at least one non-target volume. A planning processor updates at least one remaining radiation dose of a radiation therapy plan based on the determined actual radiation dose.
