摘要： A magnetic resonance imaging scan using a MR scanner receives via a user interface a MR imaging protocol categorizable into a MR scan type of a predefined set of MR scan types. Further, a database is queried by providing to the database scan information permitting the database to identify the MR scan type of the MR imaging protocol. Statistical information on the MR scan type which can include statistics on modifications of individual scan parameters of the MR scan type is received from a database, and the statistical information is provided to the user interface. Modifications of the MR imaging protocol can be received from the user interface, resulting in a modified MR imaging protocol, according to which the MR imaging scan can be performed.

摘要： A method includes obtaining image data for a patient. The image data corresponds to acquisition data from an imaging acquisition from a set of planned image acquisitions in an examination plan for the patient. The method further includes analyzing the image data with a processor based on an imaging practice guideline and producing electronically formatted data indicative of the analysis. The processor generates a signal indicative of a recommendation of a change to the examination plan based on the data indicative of the analysis.

摘要： A medical imaging device (300) includes a magnetic resonance imaging system (302) and a memory (334) containing machine executable instructions (370, 372, 374, 376, 378, 380, 382, 384, 386) for execution by a processor (328). Execution of the instructions causes the processor to receive (100, 204) a pulse sequence protocol (340). Execution of the instructions further causes the processor to determine (102, 206) a pulse sequence type classification (342) descriptive of the pulse sequence protocol. Execution of the instructions further cause the processor to determine (104, 208) a magnetic resonance contrast classification (344). The choice of the magnetic resonance contrast classification depends upon the pulse sequence type classification. Execution of the instructions further causes the processor to determine (106, 210) a pulse sequence protocol classification (346). The pulse sequence protocol classification is determined by the pulse sequence type classification and the magnetic resonance contrast classification.

摘要： The present application is directed to the idea of using sampling techniques to propagate segmentation uncertainty in order to evaluate variability in radiation planning. A radiotherapy planning apparatus (10) creates diagnostic image data of a region of interest of a subject. Image data from other sources can also be used. The image data is segmented (44) and combined with previously imaged model data. Target measures such as dose volume histograms are produced for each of the segmentations of the image data. These measures are later combined into a statistical quantification of the target measure (FIG. 3). This information is presented (52) to the user to give the user possible outcomes of the radiotherapy plan, and, e.g., confidence levels in those outcomes.

摘要： Quantitative assessment of magnetic agent tagged cells in a subject comprises: acquiring a series of T2 weighted images of the subject; acquiring a series of T2* weighted images of the subject; and generating a value indicative of quantitative assessment of magnetic agent tagged cells in the subject based on both the T2 weighted images of the subject and the T2* weighted images of the subject. The generating may be further based on predetermined relationships (26) between (i) R2 and intracellular magnetic agent concentration, (ii) R2* and intracellular magnetic agent concentration, (iii) R2 and extracellular magnetic agent concentration, and (iv) R2* and extracellular magnetic agent concentration. Said predetermined relationships may be generated based on R2 and R2* measurements of a plurality of calibration phantoms having different concentrations of substantially purely intracellular magnetic agent and having different concentrations of substantially purely extracellular magnetic agent.

摘要： The invention relates to a device (1) for magnetic resonance imaging of a body (7) placed in a stationary and substantially homogeneous main magnetic field. In order to provide an MR device (1) which is able to reconstruct a final complex image of high quality, the invention proposes that the device is arranged to simultaneously acquire MR signals via the receiving antennas (10a, 10b, 10c) with subsampling of k-space, compute intermediate MR signal data at a complete set of k-space positions from the acquired MR signals, wherein the intermediate MR signal data values are calculated as linear combinations of the acquired MR signal samples using weighting factors, which weighting factors are derived from the covariances of the acquired MR signal samples, and to reconstruct an MR image from the intermediate MR signal data.

摘要： The system 10 comprises an input 2 for accessing the suitable input data. The core of the system 10 is formed by a processor 4 which is arranged to operate the components of the system 10, it being the input 2, a computing unit 5, a working memory 6. The computing unit 5 preferably comprises a suitable number of executable subroutines 5a, 5b, 5c, 5d, 5e, and 5f to enable a constructing of a geometric model of the movable body based on the results of the segmentation step, finding a spatial correspondence between the first and second image dataset, mapping the texture image dataset on geometric model, fusing the geometric model and the mapped texture image dataset. The apparatus 10 according to the invention further comprises a coder 7 arranged to code the determined region of interest in accordance to a pre-selected criterion. The criterion may be selectable from a list of valid criteria, stored in a file 7a. Preferably, the coder 7, the computing unit 5 and the processor 4 are operable by a computer program 3, preferably stored in memory 8. An output 9 is used for outputting the results of the processing, like fused image data representing the textured, preferably animated geometric model of the movable body. The invention further relates to a method for integration of medical diagnostic information and a geometric model of a movable body and to a computer program.
