Abstract

Systems, methodologies, media, and other embodiments associated with automatically adapting MRI controlling parameters are described. One exemplary method embodiment includes configuring an MRI apparatus to acquire MR signal data using a non-rectilinear trajectory. The example method may also include acquiring MR signals, transforming the MR signals into image data, and selectively adapting the MRI controlling parameters based, at least in part, on information associated with the MR signals.

Claims

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.

2. The system of claim 1, where the MR procedure is a perfusion MRI procedure, and where the parameter processor is configured to analyze and respond to the data associated with the MR signals from the perfusion MRI procedure with respect to one or more of, a contrast change data, a contrast rate of change data, and a contrast saturation data.

3. The system of claim 1, where the MR procedure is a diffusion MRI procedure, and where the parameter processor is configured to analyze and respond to the data associated with MR signals from the diffusion MRI procedure with respect to one or more of, a water diffusion change data, and a water diffusion rate of change data.

4. The system of claim 1, where the MR procedure is a BOLD MRI procedure, and where the parameter processor is configured to analyze and respond to the data associated with MR signals from the BOLD MRI procedure with respect to one or more of, a blood oxygen change data, and a blood oxygen rate of change data.

5. The system of claim 1, comprising:

a cell manipulation processor configured to control one or more of, delivering a therapeutic agent to a portion of the object, delivering radiation to a portion of the object, heating a portion of the object, freezing a portion of the object, and depriving oxygen to a portion of the object.
