    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.

    摘要: MRI interference with a concurrently operated system may be reduced or corrected by subtracting the MRI interference from signals measured using the concurrently operated system. Various approaches for performing MRI of an anatomic region in conjunction with a radio-frequency-sensitive (RF-sensitive) measurement of the region using the concurrently operated system include the steps of simultaneously performing an MR scan sequence including MR pulses and the RF-sensitive measurements; recording the RF-sensitive measurements as they are made; detecting intervals during the MR scan sequence when an RF level is sufficient to interfere with the RF-sensitive measurements; and retaining only the RF-sensitive measurements performed outside the detected intervals.

    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.
