摘要： To efficiently, 3-dimensionally, perspectively project and display the extracting processing procedure of a predetermined region on a 3-dimensional image, the extracting process is executed while observing the displayed image. Further, the process is interrupted as necessary so that the process can progress or be returned. The result of the extraction at the interruption time point is edited on a 2-dimensional image and the result of the edition is immediately reflected onto the 3-dimensional image, so that whether the edition is proper or improper can be decided.

摘要： In order to realize multi-level gradation representation with reduced crosstalk in a display apparatus of STN method, one horizontal interval is divided uniformly by the bit length n of a gradation level display in a display apparatus of STN method having a display panel of simple matrix type and having display luminance depending upon the root-mean-square value of applied voltage. Each of sections resulting from division is associated with a display bit. The applied voltage value of the display panel in each divisional section is adjusted so that the root-mean-square voltage value difference on a divisional section may become the density difference meant by the display bit. Since time is divided into nearly equal n parts to represent a gradation level, the minimum time interval resulting from division becomes longer that of the conventional technique. Since the frequency band in use is narrowed, the crosstalk is reduced. As a result, false images and flicker on the display screen can be suppressed.

摘要： To accomplish double-slice imaging by a nuclear magnetic resonance (NMR) imaging apparatus having an ordinary radio frequency magnetic field generator, two radio frequency magnetic field waveforms are used and slices are separated by subsequent calculation. More definitely, two slice portions are excited in a REAL direction by a COS waveform and are excited in an IMAG direction by a SIN waveform. When one of the slices is S1 with the other being S2, the signal SC when the COS waveform is used is S1+S2 while the signal SS when the SIN waveform is used is i.S1-i.S2. Therefore, the calculation for separating the slices proves SC+i.SS and SC-i.SS. The present invention can avoid the increase in the production cost of the apparatus due to the addition of hardwares.

摘要： A method and apparatus for MRI imaging capable of reducing the time between end of measurement and completion of image reconstruction by performing part of image reconstruction calculation in parallel with measurement of magnetic resonance signals, which particularly performs image reconstruction calculation up to (N-1) dimensions of N-dimensional image reconstruction calculation in parallel with measurement of signals and performs the image reconstruction calculation for the remaining one-dimensional direction after the measurement has been finished. When calculation for the last one dimension is performed, the (N-1)-dimensional images for which image reconstruction has been completed are successively displayed, and the image reconstruction calculation for the remaining one-dimensional direction is carried out not by FFT but by discrete Fourier transform, or such that the order of signal measurement is made in the bit reversed order for the order of phase encoding quantity, and thereby, a further portion of the image reconstruction calculation is carried out in parallel with the signal measurement.
