摘要： A method and apparatus is provided for magnetic source magnetic resonance imaging. The method includes collecting energy signals from an object, providing additional information of characteristics of the object, and generating the image of the object from the energy signals and from the additional information such that the image includes a representation of a quantitative estimation of the characteristics, e.g a quantitative estimation of magnetic susceptibility. The additional information may comprise predetermined characteristics of the object, a magnitude image generated from the object, or magnetic signals collected from different relative orientations between the object and the imaging system. The image is generated by an inversion operation based on the collected signals and the additional information. The inversion operation minimizes a cost function obtained by combining the data extracted from the collected signals and the additional information of the object. Additionally, the image is used to detect a number of diagnostic features including microbleeds, contract agents and the like.

摘要： For optimal image quality in susceptibility-weighted imaging and accurate quantification of susceptibility, it is necessary to isolate the local field generated by local magnetic sources (such as iron) from the background field that arises from imperfect shimming and variations in magnetic susceptibility of surrounding tissues (including air). We present a nonparametric background field removal method based on projection onto dipole fields in which the background field inside an ROI is decomposed into a field originating from dipoles outside the ROI using the projection theorem in Hilbert space.

摘要： Exemplary quantitative susceptibility mapping methods, systems and computer-accessible medium can be provided to generate images of tissue magnetism property from complex magnetic resonance imaging data using the Bayesian statistical approach. The likelihood is constructed directly using the complex data. A prior is constructed from matching structures or information content in known morphology. The quantitative susceptibility map can be determined by, e.g., maximizing the posterior. Thus, according to the exemplary embodiment, system, method and computer-accessible medium can be provided for determining information associated with at least one structure. Using such exemplary embodiment, it is possible to receive signals associated with the structure(s), where the signals can include complex data that is in the complex domain.

摘要： A collapsible and reusable shipping or storage container that easily collapses to a flat stackable package with no small or loose parts. Said container can be locked with a single locking mechanism in collapsed folded position or in fully open position with items inside. Said container is collapsed for return transport to distribution center to await reloading of future contents and thereby minimizes required space and preventing waste while in transport returning to distribution facility. To fold and collapse said container, top lid slides out and is lifted diagonally and removed from container, bottom panel is released and flipped up toward front side panel, collapsible sides are folded in and removed lid is placed into designated slot within collapsed container.

The methods may include processing motion data of a target to be treated obtained from at least one marker for at least one period. Each period including a plurality of time intervals. The processing including processing the motion data to determine an isocenter for each time interval along at least one of a plurality of axes of motion. The method may include determining at least one component of the motion data in at least one axis, the at least component corresponding to a subset of the motion data having a discrete value and/or a range of values; and determining respiratory motion from at least one component of the motion data. Radiotherapy treatment can be improved by determining the respiratory motion and the impact of respiration of a target.
