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： The application discloses an apparatus and method of processing images, hand-drawn or written on a suitable Writing Surface, viewed by an Image Sensor such as a video camera, and captured by an image sensing circuit (i.e., frame grabber or similar) used for acquisition of image frames by a computer. More particularly, this invention discriminates among changes detected in these Viewed Images in order to identify and disregard non-informational, transient and/or redundant content. Removal of such content, a writer's arm for example, from the captured image facilitates isolating meaningful changes, specifically intentional new Writings and Erasures appearing on the Writing Surface. Preserving only meaningful changes on the surface promotes optimized: “video image” storage and compressed transmission of a subset of the visual data, when used in conjunction with digital computers at remote locations optionally equipped with projected image and/or conventional computer display systems. The invention provides for displaying a composite of the remote sites' changes, transmitted over conventional communications channels, omitting Local Markings where the display device is a projector. The preferred embodiment of the present invention is applied to remote presentation aids, in particular “whiteboards” such as those typically used in educational lectures and commercial sales and training settings, and in particular to remote whiteboards. As will become clear, however, the application of the present invention is not restricted to whiteboards exclusively, but can work with any Writing Surface suitable for image acquisition (e.g., flipcharts or paper on a desk). Receive-only sites may participate in the remote presentation without contributing Local Markings to the composite. The present invention is compatible with conventional software products which will carry audio and other data streams on the same channel as the compressed image signals.

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.
