摘要： Techniques are disclosed for preparing a repeat intervention on the skin of a patient. This may include acquiring first image data of an intervention region during a first intervention on the skin of the patient. At least two landmarks may be identified on the skin of the patient on the basis of the acquired first image data. A position of the first intervention is then determined with the aid of the landmarks as reference points. In addition, the position of the first intervention and of the landmarks may be stored in a data memory unit. A position of the second intervention is subsequently localized on the basis of the stored position and of the at least two landmarks.

摘要： A magnetic resonance method and system are provided for magnetic resonance (MR) image-guided insertion of an object into a biological tissue along a predetermined trajectory. The trajectory provides a path between a starting point and a target site within the tissue. Sufficiently high resolution images can be generated in real time to precisely guide the needle placement. A compressed sensing approach is used to generate the images based on minimization of a cost function, where the cost function is based on the predetermined needle path, artifact effects associated with the needle, the negligible changes in the images away from the trajectory, and the limited differences between successive images. The improved combination of spatial and temporal resolution facilitates an insertion procedure that can be continuously adjusted to accurately follow a predetermined trajectory in the tissue, without interruptions to obtain verification images.

摘要： A method for determining a change over time in a biomarker in a region to be examined of a patient is provided. The change is determined from magnetic resonance data using a magnetic resonance measuring system with sequences and protocols for measuring the biomarkers by functional resting state connectivity by rsfMRI, perfusion values, magnetic resonance spectra of voxels, or morphometry of organs. A control unit has programs which evaluates the biomarker and a data memory which stores the results of the evaluation and additional data. During a first examination, a quantity result of the biomarkers is determined and stored in the data memory. During a follow-up examination, at least one previous item of the result and additional data from the first examination stored in the data memory are used for determining a quantitative change in the biomarker.

摘要： In a method and system for planning irradiation of a patient for therapy, a first time series acquired from computed tomography scan data of the patient is provided to a processor, as is a second time series acquired from magnetic resonance scan data of the patient. A first parameter that characterizes the first time series is acquired, as is a second parameter that characterizes the second time series. The first time series and the second time series are combined in the processor using the first parameter and the second parameter. An irradiation plan is calculated in the processor using the combined first time series and second time series.

摘要： A configurable coil arrangement for use with MRI-guided procedures is provided that facilitates optimal imaging for both pre-procedure planning and imaging of the target sites during the procedure. The coil arrangement includes a plurality of connected coil elements. Spacers connecting the coil elements can be adjustable and/or deformable to provide one or more openings in the coil arrangement of optimal size for accessing the subject within the imaged region. Individual coil elements can also be removed to provide access openings during such procedures, or left in the array for improved pre- and post-procedure image quality. The MRI system can be configured to detect configurations of the coil arrangement and modify imaging parameters to optimize image quality.

摘要： A magnetic resonance imaging system and method are provided that include user control of certain functions using physical gestures, such as hand motions or the like. The gesture control aspects can include one or more cameras, and a processor configured to detect and recognize gestures corresponding to predetermined commands and to provide signals to execute the commands. A verification switch, such as a foot switch, can be included to improve safety and reliability of the gesture control aspects. This switch can be used to activate the gesture detection aspects and/or to confirm a recognized gesture command prior to its execution.

摘要： In a method and apparatus for identifying an organ structure of an examined object in magnetic resonance image data, magnetic resonance measurement data for the organ structure of the examined object are acquired by operation of a magnetic resonance scanner using a magnetic resonance sequence that specifies a sampling scheme of k-space. Magnetic resonance image data are reconstructed from the magnetic resonance measurement data. The organ structure is identified in the magnetic resonance image data. The sampling scheme of k-space is selected so as to support the subsequent identification of the organ structure in the magnetic resonance image data reconstructed from the magnetic resonance measurement data.
