摘要： If relocation of a table with a high reference frequency is made possible, the database management method and system are arranged to improve performance according to the number of increased nodes and accumulate a reference frequency of each external storage unit allocated to each database management node. A data storage area for storing the table with a high reference frequency, located in the external storage unit, is specified as a shared data area to be referenced by plural nodes. The system is controlled to cause the nodes to refer to the shared table stored in the shared data area on any timing in parallel. This prevents load from being concentrated onto the node allocated to the data area.

摘要： In the non-Cartesian measurement, image quality is improved while the advantages of non-Cartesian measurement are maintained. To realize the aforementioned, in the non-Cartesian measurement, artifacts caused by non-uniform data density in k-space are reduced. Therefore, each unit k-space is imaged by an inverse Fourier transform, the field of view of the image is enlarged in a direction in which data density is to be increased, and the image after the enlargement of the field of view is Fourier transformed and gridded as unit k-space that has a small k-space pitch in the direction in which the field of view has been enlarged and has an increased amount of data. This processing is repeated for all blades.

摘要： In a non-Cartesian sampling method, a trajectory along which a measurement space is sampled is optimized. That is, data placed on one spiral trajectory heading outward from the center of the measurement space is sampled from a plurality of echo signals. The sampling is performed such that the data is placed continuously, without overlapping, in order from the center to the outside. Alternatively, the data may be overlapped and a mismatch between echo signals may be corrected using the data of the overlapped portion.

摘要： In order to make it possible to set the optimal breath-holding imaging conditions according to the subject without extension of an imaging time or the sacrifice of image quality, one scan is divided into one or more breath-holding measurements and free-breathing measurements on the basis of the imaging conditions of a breath-holding measurement, which are input and set according to the subject, and a region of the k space measured in the breath-holding measurement is controlled. Preferably, in the breath-holding measurement, low-frequency data of the k space is measured. Moreover, preferably, imaging conditions of the breath-holding measurement include the number of times of breath holding or a breath-holding time, and the operator can set any of these values.
