摘要： In apparatus for magnetic resonance imaging equipped for parallel imaging, in the sense that an array of receive coils can be used to regenerate data at phase-encode gradients interposed between those at which measurements were taken, the full set of data is collected, which is then split into two sets with a greater separation of phase-encode gradients (Figures 13 and 14). These sets are then each regenerated (Figures 15 and 16), enabling spurious data to be excised from the original data set by comparison of the two representations.

摘要： A method of imaging a patient with an MRU scanner (10) includes imaging a region of interest of the patient with the MRI scanner (10) and acquiring image data resulting from the imaging. An image of the region of interest is reconstructed form the image data. Them method also includes generating navigator echos during the imaging, collecting the navigator echos and deriving, from each navigator echo, a measurement of patient motion experience during the imaging. A historical record of the measurements is maintained. Parameters for the acquisition of image data are selected to compensate for motion, or specific image data is selected for reconstruction, based on the historical record.

摘要： An x-ray tube (1) includes a heat shield (130) which intercepts heat radiating from an anode (10), thereby reducing the temperature of a bearing assembly (62). The heat shield includes outer and inner concentric cylinders (132, 134) spaced from each other by a vacuum gap (138). The heat shield and a stationary portion (114) of the bearing assembly are both connected to a cold plate (150) so that heat is not conducted from the cylinders to the bearing assembly but is instead carried away by the cold plate to the surrounding cooling oil.

摘要： An apparatus for computed tomography (CT) imaging of a cyclically moving organ includes a positional state monitor (24, 40) that monitors a positional state of the cyclically moving organ such as the heart. A cone-beam CT scanner (10) acquires image data at least within a plurality of time windows. Each time window is centered about an occurrence of a selected positional state of the organ. A window analyzer (38) selects a data segment within each time window such that the data segments combine to form a complete data set covering a selected angular range. A reconstruction processor (44) reconstructs the selected data segments into an image representation.

摘要： A CT scanner (10) for obtaining an image of a subject includes a stationary gantry (12), and a rotating gantry (14) rotatably supported on the stationary gantry (12) for rotation about the subject. A fluid bearing is interposed between the stationary gantry (12) and the rotating gantry (14) by means of radial and axial fluid bearing pads, (100) and (102) respectively. The fluid bearing provides a fluid barrier which separates the rotating gantry (14) from the stationary gantry (12). In a preferred embodiment, the fluid bearing provides for quieter CT scanner operation at high rotational speeds. Moreover, eliminating the physical contact between the gantries minimizes wear and optimizes longevity.

摘要： A magnetic resonance imaging apparatus (10) and method performs spatial encoding of magnetic resonance signals and collects data along a preselected k-space trajectory (78, 78', 79, 88, 98, 98', 108, 118, 128, 129, 148, 158). The k-space trajectory covers a plurality of intersecting planes (94, 96; 114, 116) or partial planes of k-space data (74, 76; 84, 86; 104, 106; 124, 126; 144, 146; 154, 156; 180, 188; 190, 198) without sampling data for the entire volume (70, 80, 90, 100, 110, 120) of k-space. In this manner, volumetric image data can be collected in a single, or a relatively small number of, excitation periods.

摘要： The signal of an echo planar imaging pulse sequence includes first and second distinct sets of echos. Each echo (114a) in the first second set of echos coincides with a positive negative polarity read gradient (112a). A first image of a region of interest is reconstructed from the first set of echos, and a second image of the region of interest is reconstructed from the second set of echos. Preferably, the two images are temporally offset from one another, and cine or fluoroscopic imaging is achieved by alternating the frames thereof between iteratively produced first and second images.

摘要： A dual filament x-ray tube assembly (16) includes an evacuated envelope (52) having an anode (54) disposed at a first end of the evacuated envelope (52) and a cathode assembly (62) disposed at a second end of the evacuated (52). The cathode assembly includes a variable-length filament assembly (72,74; 100) which emits electron beams for impingement on the anode (45) at focal spots having varying lengths. The cathode assembly (62) further includes a cathode cup which is subdivided into a plurality of electrically insulated deflection electrodes (64,66,68; 110, 112). A filament select circuit (80) selectively and individually heats a portion of the variable-length filament assembly (72,74). Electron beams emitted from the filament assembly (72,74) are electrostatically focused and controlled by applying potentials to different ones of the deflection electrodes (64,66,68; 110,112).
