摘要： A method for validating non-rigid image registration includes acquiring a source image and a target image. Registration is performed from source image to target image using a non-rigid registration technique to produce forward transformation map. Registration is performed from the target image back to the source image using the non-rigid registration technique to produce a backward transformation map. Consistency registration error is measured as an indication of a change in local volume of the source with respect to the target image using the produced forward transformation map and the produced backward transformation map. The non-rigid registration technique is validated based on the measured consistency registration error.

摘要： Methods and a system to unify reconstruction and motion estimation steps in first pass cardiac perfusion MRI include a global objective function that meets data consistency, spatial smoothness, motion and contrast dynamics constraints. The global objective decomposed into simpler sub-problems which include low pass filtering of a deformed object, TV shrinkage, analytical Fourier replacement and an l2 minimizing problem. A registration tool based on the local cross-correlation similarity measure and enabled to perform both rigid and flexile deformations, is applied. Registration parameters are tuned by rigid, semi rigid and flexible models at different stages of iterations. A system to perform the methods is also disclosed.

摘要： A method for correcting registration misalignment in magnetic resonance perfusion images includes receiving a time series of magnetic resonance images of an anatomical organ, each image comprising a plurality of intensities defined on an N-dimensional domain of points, performing a first group-wise registration of all images in the time series of images using a pair-wise registration as an initialization, detecting a misaligned image from the group-wise registration by analyzing a total variation of intensity differences between consecutive images, and correcting the misaligned image by optimizing a second group-wise energy function over registration parameters of the misaligned image.

摘要： Embodiments of the present disclosure provide methods, devices and a computer readable medium for a restriction on a measurement for a neighbor cell. According to a method implemented by a network device in a communication system, the network device determines a neighbor cell on a frequency layer capable of cell reference signal (CRS) muting. A cell reference signal in the neighbor cell is transmitted on a predetermined physical resource if the neighbor cell enables CRS muting. In response to the determination, the network device transmits measurement restriction information to a terminal device in a cell of the network device. The measurement restriction information indicates that a radio resource management (RRM) measurement for any neighbor cell on the frequency layer is restricted to be performed on the predetermined physical resource. The embodiments of the present disclosure improve a measurement for a neighbor cell.
