摘要： An image display apparatus having a computer system (100) and an image processor (500). The computer system (100) includes: a personal computer having a CPU (210) and a main memory (220); and input/output apparatuses such as magneto-optical disk drive (300), image scanner (330), color printer (340), etc. The image processor (500) which commonly uses a system bus (150) of the computer system (100) includes an independent dedicated image bus (550), a compression/expansion unit (510), an image memory read/write controller (520), image memories (610, 620, 630), and a video processor (650). Image data which is sent from the magneto-optical disk drive (300) is decoded by the compression/expansion unit (510) and is held in the image memories. The image data of the image memories is transferred to the video processor (650) through a dedicated signal line and is displayed on a large screen projection display (700).

摘要： Ein Magnetresonanz-Messgerät, das in der Lage ist, im Vergleich zu einem verwandten Magnetresonanz-Messgerät ein kernmagnetisches Resonanzsignal mit einer höheren Empfindlichkeit und einer höheren Auflösung zu erkennen. Das Magnetresonanz-Messgerät moduliert ein kernmagnetisches Resonanzsignal durch Anwenden einer Schwingung (Schallwelle) einer bekannten Frequenz, die höher als die Frequenz des kernmagnetischen Resonanzsignals ist, auf ein Untersuchungsobjekt, und erkennt das modulierte Signal durch Ausführen einer Lock-in-Detektion, die es dem Magnetresonanz-Messgerät ermöglicht, das kernmagnetische Resonanzsignal mit einer hohen Empfindlichkeit zu erkennen. Nach dem Bestrahlen einer lokalen Fläche des Objekts mit einer Ultraschallwelle und dem Modulieren des kernmagnetischen Resonanzsignals, das von der bestrahlten lokalen Fläche abgeleitet wird, kann das Magnetresonanz-Messgerät des Weiteren das kernmagnetische Resonanzsignal mit einer hohen Auflösung erkennen.

摘要： An ultrasonic medical treating device suited for ultrasonic medical treatment of a prostate, capable of sighting a converging ultrasonic wave for the treatment precisely to a target portion, and preventing displacement from the target portion being irradiated effectively. An ultrasonic transducer (5) for generating a converging ultrasonic wave for treatment is arranged together with an imaging ultrasonic probe (6) in an applicator (4), and an ultrasonic transducer (2) for monitoring the sight of and the position displacement is provided in a catheter inserted in a ureter. Imaging means (7) drives the ultrasonic probe (6) to display an ultrasonic tomogram of the target portion and its vicinity on display means (10). The ultrasonic transducer (2) is driven pulsationally with the same frequency as that of the imaging ultrasonic wave at the timing at which the imaging ultrasonic wave, so that a point sound source image indicating the position of the transducer (2), as viewed from the applicator, is superimposed on the ultrasonic tomogram displayed on the display means (10). The position displacement of the applicator being irradiated with the converging ultrasonic wave can be monitored by monitoring the displacement from the position of the point sound source image at the end of the position adjustment of the applicator.
