Abstract:
1. A system, comprising: a magnetic resonance imaging (MRI) apparatus configured to acquire a magnetic resonance (MR) signal from an object during an MR procedure using a non-Cartesian trajectory without acquiring information associated with a catheter inserted into the object, the apparatus being controlled, at least in part, by a value of an imaging parameter, where the MR signal is suitable for making an MR image of the object, where the value of the imaging parameter controls, at least in part, the MR image of the object, and where the non-Cartesian trajectory is one of a two-dimensional hybrid imaging sequence, a two-dimensional non-rectilinear k-space trajectory, a three-dimensional radial imaging sequence, a three-dimensional hybrid imaging sequence, a rosette trajectory, a three-dimensional non-rectilinear k-space trajectory, a single value decomposition (SVD) encoding, a wavelet encoding, and a direct temporal encoding; a memory configured to store the imaging parameter; a parameter processor configured to selectively automatically adapt, substantially in real time, the imaging parameter during the MR procedure based, at least in part, on analyzing one or more attributes of the object as provided in data associated with the MR signal without analyzing an attribute of a catheter, where the imaging parameter includes three or more of, a temporal resolution parameter, a spatial resolution parameter, a field of view (FOV) parameter, a slice position parameter, a slice orientation parameter, a slice thickness parameter, a slice rotation parameter, a bandwidth parameter, a time to repetition (TR) parameter, a time to echo (TE) parameter, time from inversion (TI) parameter, a pulse sequence type parameter, a number of projections per MR signal acquisition period of time parameter, and number of interleaves per MR signal data acquisition period of time parameter, where the imaging parameters are values stored in the data store configured to store the imaging parameter, and; an image processor configured to display an image of the object.
