Abstract: A system and method for multi-spectral MR imaging near metal include a computer programmed to calculate an MR pulse sequence comprising a plurality of RF pulses configured to excite spins in an imaging object and comprising a plurality of volume selection gradients and determine a plurality of distinct offset frequency values. For each respective determined offset frequency value, the computer is programmed to execute the MR pulse sequence having a central transmit frequency and a central receive frequency of the MR pulse sequence set to the respective determined offset frequency value. The computer is also programmed to acquire a three-dimensional (3D) MR data set for each MR pulse sequence execution and generate a composite image based on data from each of the acquired 3D MR data sets.

Abstract: Changes in the diameter of a fiber are determined by directing a laser beam transversely onto the fiber and directing a fringe produced by the scattering of the beam to a photodiode array by means of a transforming lens. Circuitry is provided to detect movement of the fringe on the diode array thereby indicating changes in the diameter of the crystal fiber.

Abstract: Disclosed is a high speed memory system having a parallel architecture which is particularly advantageous in controlling a multiline raster scanned display. Data for a plurality of scan lines is processed in parallel, and pixel data for each of a plurality of scan lines is stored in a plurality of memory segments which can be accessed in parallel. Latch means is provided with each memory segment for latching pixel data for scan line control in order to allow continued manipulation of data stored in the memory segment while scan line data is extracted. A plurality of scan line processors are connected to a common bus which provides transformed data of primitives in display coordinates. Each scan line processor controls data for a plurality of scan lines, and a plurality of memory segments are connected with each scan line processor for storing and manipulating pixel data for the plurality of scan lines.
