摘要： There are provided an ultrasonic imaging system and method which can correct a phase shift effect to image a real change in acoustic impedance in a living body.An ultrasonic probe transmits an ultrasonic beam to an object to receive an echo. A transmit beamformer transmits a transmit signal via transmit/receive SWs to the probe in delay time matched with a transmit focal point according to the signal under the control of a control system. An ultrasonic signal returned from the object to the probe is converted to an electric signal by the probe to be transmitted via the transmit/receive SWs to a complex receive beamformer. The complex receive beamformer performs dynamic focus adjusting delay time according to reception timing. A phase shift correction part uses the output of the complex beamformer outputting beams of a real part and an imaginary part to correct phase shift. due to frequency-dependent attenuation, correct phase shift in the lateral direction of the beam, or correct both. After phase shift correction, an acoustic impedance change amount operation part obtains a derivative about the space position of acoustic impedance. The signal subject to filtering processing is image displayed via a scan converter on a display part.

摘要： A correction table unit (5) contains correction tables for correcting output values of image data of the first image, the second image, . . . , the n-th image successively output from an X-ray plane detector (4) of a radiographic image diagnosis device and having different output rise characteristics. After correction of the image data, the second image data is subtracted from the first image data, . . . , and the n-th image data is subtracted from the first image data by a subtraction unit (8). As a result, a subtraction image, i.e., an angiographic image is displayed on display means (9). Since the affect of the different rise characteristics of each image data is eliminated, it is possible to obtain an angiographic image having a uniform background brightness and a preferable contrast.

摘要： Provided is a magnetic resonance imaging system capable of reducing degradation in a magnetic resonance spectrum derived from a change in a static magnetic field. A sequence controller performs non-water-suppressed spectrum measurement (pre-scan) cyclically during water-suppressed spectrum measurement (main scan) accompanied by repetitive measurement intended for averaging of signals, and cyclically detects a water resonant frequency (water-signal peak position) and a phase value at a water-signal peak from an obtained non-water-suppressed spectrum (the cyclic pre-scan makes it possible to sense a time-varying rate of static magnetic field strength (resonant frequency)). For the water-suppressed spectrum measurement (main scan) succeeding the pre-scan, a reception-initiating phase value that is used to detect a magnetic resonance signal is set to a value calculated using the phase value at the water-signal peak position detected during the pre-scan. For averaging of measured magnetic resonance signals, data items are shifted by the value calculated from the phase value at the water-signal peak position detected during the pre-scan. Thereafter, the averaging is carried out.
