摘要： Techniques for correcting measurement artifacts in MR thermometry predict or anticipate movements of objects in or near an MR imaging region that may potentially affect a phase background and then acquire a library of reference phase images corresponding to different phase backgrounds that result from the predicted movements. For each phase image subsequently acquired, one reference phase image is selected from the library of reference phase images to serve as the baseline image for temperature measurement purposes. To avoid measurement artifacts that arise from phase wrapping, the phase shift associated with each phase image is calculated incrementally, that is, by accumulating phase increments from each pair of consecutively scanned phase images.

摘要： Techniques for temperature measurement and correction in long-term MR thermometry utilize a known temperature distribution in an MR imaging area as a baseline for absolute temperature measurement. Phase shifts that arise from magnetic field drifts are detected in one or more portions of the MR imaging area, facilitating correction of temperature measurements in an area of interest.

摘要： A focused-ultrasound or other procedure for treating a target within a tissue region can be planned iteratively by creating a treatment plan specifying a treatment location pattern and stimuli applied thereto, simulating the treatment, computationally predicting an effect of the simulated treatment, comparing the predicted effect against one or more treatment constraints (such as efficacy and/or safety thresholds), and, if a constraint is violated, repeating the simulation for an adjusted treatment plan.
