摘要： In magnetic resonance imaging ("MRI"), RF power is applied to a region of interest within the patient by a local antenna disposed adjacent the region of interest. The local antenna is excited by RF signals sent through free space from a principal antenna mounted to the primary field magnet of the MRI system. The principal antenna includes one or more loops mounted so that the plane of the loop is transverse to the pole pieces of the magnet frame and so that the plane of the loop is transverse to adjacent metallic portions of the frame. The loops are aligned with openings in the frame so that a patient is advanced into a frame through the loop. The loops do not substantially obstruct axis to the subject receiving space.

摘要： Patient treatment is carried out under magnetic resonance imaging (MRI) guidance. The treated region of anatomy may be a joint, an organ or other tissue, or a tumor. Instruments which can be guided by MRI allow the treated region of anatomy to be reached along a selected path, curved or straight, to reduce issue injury. The delivery of treatments under MRI guidance and monitoring provides a method of identifying a preferred treatment regimen.

摘要： Magnetic resonance imaging systems typically have a single patient handling system which allows the sequential scanning of individual patients. Such apparatus limit patient throughput and consequently the utility of magnetic resonance imaging systems. The present invention includes apparatus and methods to enhance patient throughput of a magnetic resonance imaging system, particularly as related to imaging the breast region of patients. Two distinct components of a magnetic resonance imaging procedure are defined: the patient handling time and the scan protocol time, and these time components are multiplexed to enhance patient throughput. This is achieved by addition of patient handling systems at additional apertures as exist on the primary field magnet and which provide access to the imaging volume. It is thus possible, for example, to have the patient handling time component of one patient overlap with the scan protocol time component of a second patient. Additionally, the present invention includes radio frequency antennas and positioning devices designed for use in scanning the breast region of patients.

摘要： A method and system for correlating slice profiles associated with a series of magnetic resonance images taken at a plurality of positions. The method comprises first positioning a patient in a first position in the imaging volume of the magnet. A scout scan is then acquired. Selection is then made of an anatomical landmark in the scout scan, which will be referred to as an anatomical fiducial. A particular slice, typically one of a stack of slices to be acquired in a subsequent scan, is selected and precisely positioned at the location of the anatomical fiducial in the scout scan. Following completion of the scan, the patient may be repositioned, necessitating a new scout scan to set up parameters for a second scan.

摘要： The present invention relates to a method for monitoring the presence of, or the susceptibility to multiple sclerosis. The method may include obtaining measurements of the cerebrospinal fluid (CSF) flow in a patient using magnetic resonance imaging, and deriving one or more values representing the CSF flow in the patient. These values may be used to determine if the patient has abnormal CSF flow, as such abnormal CSF flow may be indicative of presence of, or susceptibility to multiple sclerosis. The present invention also discloses that magnetic resonance images may be obtained on patients in various positions, including the upright position.

摘要： A magnetic resonance imaging magnet includes a ferromagnetic frame. A pair of generally toroidal superconducting coil units overlie interfaces of side walls incorporated in the frame. Each coil unit may include a vessel having hollow support extensions extending into recesses in the side walls. The coil units may further include elongated, low-thermal conductance supports disposed within the support extensions. The frame may include pole stems projecting inwardly from the side walls, and the coils may be disposed in close proximity to the pole stems. Cryocoolers may be mounted to the frame so that the cryocoolers are substantially mechanically isolated from the coils of the coil units, but are in thermal communication therewith. The cryocooler mountings may be arranged for convenient servicing and installation of the cryocoolers.

摘要： A patient is examined by magnetic resonance imaging in different positions relative to gravity by moving the patient relative to the magnet, and the acquired data is compared to show differences in anatomy due to differences in patient position. Individual data elements or groups of plural data elements representing particular locations in one set of image data can be compared with data elements associated with the same locations in another set of image data, to yield a set of comparison image data elements. The comparison data set can be used to detect difference caused by differences in position of the patient.
