Abstract: Disclosed are a magnetic resonance temperature correction method based on k-space energy spectrum analysis and a system. The method includes: filling a k-space data matrix of magnetic resonance with zeros row by row, and performing an inverse Fourier transform on the k-space data matrix after filling each row of zeros, to obtain a reconstructed image; drawing a pixel intensity variation curve according to a pixel intensity of each pixel in all reconstructed images and a number of rows filled with zeros, and obtaining echo error according to the pixel intensity variation curve, calculation an actual echo time, and calculating a corresponding temperature variation value based on the TE of each pixel.

Abstract: A device (e.g., a secondary cache device) manages descriptors which correspond to storage locations (e.g., cache blocks). The device includes memory and a control circuit coupled to the memory. The control circuit is configured to arrange the descriptors, which correspond to the storage locations, into multiple queues within the memory based on storage location access frequencies. The control circuit is further configured to determine whether an expiration timer for the particular descriptor has expired in response to a particular descriptor reaching a head of a particular queue. The control circuit is further configured to move the particular descriptor from the head of the particular queue to a different part of the multiple queues, wherein the different part is identified based on access frequency when the expiration timer for the particular descriptor has not expired, and not based on access frequency when the expiration timer for the particular descriptor has expired.
