摘要： A parenchymatous tissue image and a blood vessel image are synthesized as follows. First, a tomographic image of a specific cross section of the parenchymatous tissue image is synthesized with the blood vessel image closer to the viewpoint along the Z-axis than the tomographic image. Then, the resulting image is displayed. Thereafter, the operator inputs specific data from operation unit including a mouse and a keyboard, thereby changing the position of a displayed tomographic image along the Z-axis. This enables the operator to sequentially display two-dimensional tomographic images (B-mode images) constituting a three-dimensional parenchymatous tissue image as if to turn over the pages of a book.

摘要： The gantry of a magnetic resonance imaging apparatus includes a static magnetic field magnet, a gradient coil, a high-frequency coil, and a sealed vessel housing the gradient coil. The sealed vessel is made of a nonconductive material. Even if a gradient magnetic field is switched at high speed, no eddy current flows in the sealed vessel. Therefore, the sealed vessel does not vibrate.

摘要： An ultrasound beam is repeatedly transmitted and received to and from an object, so that an echo signal is repeatedly obtained. A velocity of each of a plurality of portions on the ultrasound beam is calculated based on the echo signal. A position of at least one specific portion of the plurality of portions is tracked in as it changes with the passage of time based on the velocity to obtain a path where the specific portion moves. Conventionally the change of brightness of the M-mode image was tracked to obtain the path. According to the present invention, since the path is obtained based on the velocity having high resolution, the accuracy of track can be improved.

摘要： An apparatus for observing blood flow patterns by utilizing ultrasonic beams which includes at least a pulse generator, a transducer, first and second phase detectors, and a monitor. The ultrasonic beams are transmitted and received by the transducer to obtain echo signals reflected from the body. The echo signals are phase-detected by the first phase detector to derive pulsed Doppler signals. The pulsed Doppler signals are phase-detected by the second phase detector to derive phase difference signals between the sampled pulsed Doppler signals. The sampling periods are determined in accordance with a depth of the body along a travel path of the ultrasonic beams. The blood flow patterns of the blood cells of the body are displayed on the monitor by processing the phase difference signals.

摘要： In an ultrasound transmitting or receiving apparatus, a plurality of ultrasound transducer elements comprising an ultrasound probe are arranged along a line to transmit and receive ultrasonic waves. For the purpose of sequentially transmitting and receiving an ultrasound beam through the transducer elements, variable-delay circuits are provided for applying delay times to the transmitting signals and/or the received signals. The variable-delay circuits include memory control devices, the addresses of which correspond to the respective azimuthal directions of transmitting and receiving the ultrasound beam. The outputs of the memory devices are connected to control terminals of transfer switches, which in turn are connected to tapped delay lines. The memory devices produce control codes such that the tapped delay lines produce predetermined delay times which control the azimuthal directions of transmitting or receiving the ultrasound beam.
