Abstract: In a magnetic resonance coil selection method and selection computer, a range parameter of a target region (ROI) to be detected is acquired, and a detection range parameter of each available coil is acquired. A coil having a detection range that overlaps with a range of the ROI is determined and then selected. The selected coil is then used in the operation of a magnetic resonance scanner to acquire magnetic resonance data. The SNR of the magnetic resonance scanner is thereby increased, so as to improve the imaging quality.

Abstract: Disclosed in embodiments of the present invention are a local coil for an MRI system and a method of use, and an MRI system. The local coil comprises: a storage module, for storing a coil file, the coil file comprising configuration attribute information of the local coil; an interface module, for communication with the outside; a control module, for reading the coil file from the storage module and sending the coil file to the outside via the interface module, or receiving the coil file from the outside and storing the coil file in the storage module.

Abstract: Machine logic (for example, software) for cache management. comprising cache management method includes the following operations: determining, in response to a cache entry is created, a category for the cache entry; and determining a predicted time point of an invalidation event associated with the category, wherein occurrence of the invalidation event will cause invalidation of catching entries of the category; setting a valid period of the cache entry based on the predicted time point.

Abstract: According to an aspect, a method for correcting an invalid script in a web application includes determining an invalid reference in an invalid script. A storage location is determined in a database corresponding to the invalid reference based on a data relationship mapping, wherein the data relationship mapping indicates the correspondence between the reference and a storage location in the database. An up-to-date value at the storage location is queried and he queried up-to-date value is determined to be the correct value of the invalid reference.
