摘要： Systems and methods for landmark correction in Magnetic Resonance Imaging (MRI) are provided. One method includes acquiring at least one calibration image or at least one localizer image of an object, identifying in the calibration or localizer images a region of the object as a reference point, wherein the reference point defines a landmark position. The method further includes determining an offset between an initial landmark position and the identified landmark position. The method also includes using the determined offset for MRI.

摘要： A variable view imaging system for observation of micro object with variable view orientation and position includes a telecentric lens group, a scanning mirror, wedge prisms, a deformable mirror and related optical elements. The combination of a scanning mirror and a telecentric lens group decouples the motion of scanning mirror and the view angle. The view angle is determined only by the angle of the wedge prisms. This design increases the zenith angle of the view and simplifies the kinematics of the system. The wedge prisms and the scanning mirror can supply a flexible view in a compact way. The wavefront error induced by the wedge prisms is corrected by the deformable mirror. In order to achieve the desired view state during operation, the scanning mirror angle and the wedge prisms angle are calculated iteratively based on the kinematics and Jacobian matrix of system.

摘要： Techniques for removing image autoflourescence from fluorescently stained biological images are provided herein. The techniques utilize non-negative matrix factorization that may constrain mixing coefficients to be non-negative. The probability of convergence to local minima is reduced by using smoothness constraints. The non-negative matrix factorization algorithm provides the advantage of removing both dark current and autofluorescence.
