Abstract: The present disclosure relates to a system and a method. The system may include a magnetic resonance imaging (MRI) apparatus configured to acquire MRI data with respect to a region of interest (ROI) and a therapeutic apparatus configured to apply therapeutic radiation to at least one portion of the ROI. The MRI apparatus may include a plurality of main magnetic coils arranged coaxially along an axis, a plurality of shielding magnetic coils arranged coaxially along the axis, and a cryostat in which the plurality of main magnetic coils and the plurality of shielding magnetic coils are arranged.

Abstract: A leakage compensation dynamic register, a data operation unit, a chip, a hash board, and a computing apparatus. The leakage compensation dynamic register comprises: an input terminal, an output terminal, a clock signal terminal, and an analog switch unit; a data latch unit for latching the data under control of the clock signal; and an output drive unit for inverting and outputting the data received from the data latch unit, the analog switch unit, the data latch unit, and the output drive unit being sequentially connected in series between the input terminal and the output terminal, and the analog switch unit and the data latch unit having a node therebetween, wherein the leakage compensation dynamic register further comprises a leakage compensation unit electrically connected between the node and the output terminal.

Abstract: A data storage and query method supporting an agile development and horizontal scaling, in a field of computer applications, includes steps of: transforming data into a 2-tuple (Key, MiniTable) and identifying any MiniTable (having a data set removed) with a unique Key, wherein the MiniTable includes multiple data columns; a structure of each data column is limited by a pre-defined mode; and the data columns are sorted according to a primary key defined by the mode. The data storage and query method obtains a capability of the horizontal scaling via removing dependency among the data sets, and a capability of the agile development via supporting an analogous SQL grammar by saving dependency among the data within the data sets. The data storage and query method can be applied to a data management system which supports the horizontal scaling of big data and the agile development of short development lifecycles.
