摘要： A system for automatically adapting image acquisition parameters based on imaging and/or device tracking feedback is provided. An example system includes a subsystem for acquiring images (e.g., MR) of an object and tracking data for a device (e.g. catheter) inserted into the object and controllably moveable within the object. The system also includes an image processor for processing the images and a device tracking logic for computing device parameters (e.g., speed, direction of travel, rate of speed change, position, position relative to a landmark, device orientation). Based on the images and device parameter computations, a parameter control and adjustment logic can automatically update one or more image acquisition parameters that control the image acquisition subsystem.

摘要： A method of automatically adjusting at least one MR image parameter for an interventional procedure includes adaptively tracking an MR micro-coil catheter and automatically updating an imaging scan plane's position and orientation, as well as other features including, but not limited to, field-of-view, resolution, temporal resolution, slice thickness, tip angle, and TE. The disclosed system provides a more natural interface for a physician operating the MR scanner during an interventional procedure. The scanner can react to changes in the clinical environment and automatically adjust a number of image parameters. For example, during catheter insertion, images are acquired at lower resolutions, and possibly larger fields of view, to help facilitate faster updates and tracking. Once the catheter reaches a target area in the tissue and its motion slows, an MR image of higher resolution, and possibly lower field of view, is acquired.

摘要： An improved imaging technique and apparatus for direct temporal encoding of spatial information of an object is presented. The signal collected from the object after application of excitation energy in a magnetic field is directly representative of the spatial position of the object without the need for the signal to undergo mathematical transformation. This is a result of the excitation scheme that generates transverse magnetization across the field of view that is a function of X (read-out) and Z (slice select) positions, resulting in a two-dimensional phase profile that, upon application of a constant gradient along the Z axis, elicits a signal that is directly attributable to the spatial position along the read-out dimension without application of mathematical transformation.

摘要： A new and improved method for tracking and/or spatial localization of an invasive device in Magnetic Resonance Imaging (MRI) is provided. The invention includes providing an invasive device including a marker having a chemically shifted signal source with a resonant frequency different from the chemical species of the subject to be imaged, applying a pulse sequence, detecting the resulting RF magnetic resonance signals, and determining the 3D coordinates of the marker. The invention also includes generating scan planes and reconstructing an image from the detected signals to generate an image having the marker contrasted from the subject. The invasive device includes a marker having a chemically shifted signal source which has a resonant frequency different from the chemical species of the subject to be imaged for use in tracking the device during imaging.

摘要： In a pH measurement system, a magnet defines a BO magnetic field with which selected dipoles preferentially align in an examination region. A orbital angular momentum system endows electromagnetic (EM) radiation with orbital angular momentum (OAM) and transmits the OAM endowed EM radiation to the examination region to at least one of (1) enhance the preferential alignment of the selected dipoles with the BO magnetic field and (2) excite the aligned dipoles to resonate. A receive coil receives resonance signals from the resonating dipoles. An analysis or measurement unit determines a pH in the examination region by analyzing the resonance signals.
