    摘要: An optical pick-up device includes a light source for irradiating a recording medium to record and/or reproduce information, an objective lens for condensing beams of the light which are reflected or transmitted by the recording medium, an optical member such as a parallel plane plate or a diffraction grating for imposing a diffraction pattern upon the condensed light, and a photo detector for detecting the presence and amount of the patterned light in each of a plurality of regions. The regions on the photo detector correspond to those created by lines curved in accordance with a comatic aberration of the optical member. In particular, the curved lines correspond to the projection of first and second rectilinear lines through the objective lens and the optical member onto the photo detector. The first rectilinear line is parallel to a track on the recording medium, and the second rectilinear is perpendicular to the track.

    摘要: In a compatible recording and reproducing apparatus which is capable of recording and reproducing information on both a video disk and a digital audio disk, a relative angle between an optical axis of a laser beam emitted from a pickup and the disk is adjusted so as to be suitable for the disk loaded on the apparatus. Further, the movement of the pickup in the radial direction of the disk is regulated in accordance with the difference in the outer diameter of the two kinds of disks. A problem due to the difference of the track pitch in the two kinds of disks is solved by moving the pickup in a direction perpendicular to a radial direction of the disk. In addition, an objective lens for focusing the laser beam on the disk is selected within a predetermined range of an effective numerical aperture in order to simplify an optical system of the apparatus.

    摘要: In an NMR diagnostic apparatus, it is generally necessary to tune a receiver tuning unit with respect to a patient. The NMR diagnostic apparatus is comprised of a standard signal generator for generating a CW signal, a receiver tuning unit which is mainly constructed by a receiver probe head and a series circuit of a capacitor and a variable capacitance diode and receives the NMR signals induced from the CW signal, quadrature detectors which detect the NMR signals, and a signal processor which processes the detected NMR signals so as to produce the control voltages "Vc". The automatic tuning operation is carried out in such a manner that varying the control voltage "Vc" which is applied to the variable capacitance diode enables the receiver tuning unit to be tuned with respect to the object that is positioned in the receiver probe head.

    摘要: An ECG-prep scan is used to set an optimum time phase in both systole and diastole of the heart. At each of the different time phases, an imaging scan is started to acquire a plurality of sets of echo data. An artery/vein visually separated blood flow image is produced from the echo data. The imaging scan uses a half-Fourier technique, for example. This provides high-quality blood flow images with shorter scan time, without injecting a contrast medium. Additionally, with a readout gradient pulse applied substantially parallel with a direction of slowly flowing blood, a scan is performed in synchronism with an optimally determined cardiac time phase. The readout gradient pulse has a dephasing pulse for enhancing differences in a flow void effect depending on blood flow velocities. This enables slow-speed flows, such as blood flows in the inferior limb, to be depicted without fail.

    摘要: A magnetic resonance imaging apparatus includes a first blood flow image acquisition unit and a second blood flow image acquisition unit. The first blood flow image acquisition unit acquires a first blood flow image of a breast of an object without contrast medium. The second blood flow image acquisition unit acquires a second blood flow image without contrast medium with applying a spin labeling pulse by which a region to be tagged is set based on the first blood flow image as a reference image so as to distinguish blood flowing into a desired region.
