Abstract: Disclosed is tuning and matching devices and methods, magnetic resonance imaging (MRI) equipment, and display interaction devices. The MRI equipment may include a transmitting coil. The tuning and matching control device may be connected with the transmitting coil and configured to perform tuning and matching on the transmitting coil. The display interaction device may be in a scanning room. The tuning and matching method may include: first obtaining curve information of a tuning curve, if determining that the curve information of the tuning curve to be displayed is not within a set information range, adjusting layout information of the tuning curve to be displayed in a display interface, and displaying the adjusted tuning curve in the display interface.

Abstract: Systems and methods for image data management are provided. The methods may include by running a first process, storing raw data collected in a scan of a subject into first storage space of the at least one storage device, and generating first information relating to the raw data. The methods may include by running a second process, obtaining the first information from the first process and storing the first information into second storage space of the at least one storage device. The methods may further include reconstructing the raw data into a reconstruction image of the subject based on the first information.

Abstract: The present disclosure provides systems and methods for material decomposition. The systems may obtain scan projection data of a target object. The systems may determine corrected projection data by correcting, based on one or more pixel parameters, the scan projection data. The systems may also determine a reconstructed image by performing, based on the corrected projection data, image reconstruction. The systems may further determine density distribution images of at least two target materials of the target object by decomposing the reconstructed image.
