摘要： A Doppler ultrasonic diagnostic apparatus for measuring or displaying the velocity information of moving members within an organism by transmitting and receiving ultrasonic waves is used for ultrasonic diagnosis in the medical filed and the like. The apparatus is composed of a transmission circuitry for producing two ultrasonic waves having different repetition periods and outputting an ultrasonic wave after change-over between them; a velocity calculating means for calculating the velocities of moving reflective members on the basis of the received Doppler signals from the two ultrasonic waves, for example, a velocity calculator or an autocorrelator for obtaining the autocorrelation of a received signal after converting it to a complex signal; a memory for storing the velocity information signals obtained by the velocity calculating means; and other calculating means. The velocity of the moving reflective members is obtained by calculating the difference between or the sum of the two kinds of velocity signals, or calculating the conjugate product or the complex product of the two kinds of velocity signals. The present invention makes it easy to obtain accurate velocity information by an apparatus having a simple structure.

摘要： An ultrasonic blood flow imaging method for two-dimensionally displaying the velocity distribution of a blood flow within a body to be examined is characterized in that the velocity distribution is displayed as a color picture in which the velocity direction is represented by one color when positive and by another different color when negative, and the magnitude of the velocity is represented by varying the brightness of the color concerned. An ultrasonic imaging apparatus for carrying out this method comprises an ultrasonic transmitter/receiver which outputs a tomographic image signal corresponding to a specific region of an object, and an average velocity signal and a velocity deviation signal corresponding to the velocity of blood flow within the specified region. These signals are stored in respective frame memories and then processed by a color processor to produce a color video signal which is input to a color display for displaying a tomographic image, and the velocity and velocity deviation of the blood flow.

摘要： CT imaging is performed twice (S1101), which is set as the normal number of rotaions, and a sinogram is corrected (S1102) based on the sinogram obtained by performing CT imaging twice. Since the cycles of data variation caused by respiration are controlled so as not to overlap one another, usually the data variations caused by respiration are eliminated by performing CT imaging twice. However, depending on irregularity in the respiration cycle of the subject, data variation components sometimes overlap at the same angle in spite of the fact that the cycles of data variation caused by respiration are controlled so as not to overlap one another. Therefore, when data variation components remain overlapped at the same angle, CT imaging is performed one additional time (S1104) and the sinogram is corrected (S1102) using the sinogram obtained by performing the additional CT imaging.

摘要： In an ultrasound diagnostic apparatus for forming a Doppler image, a plurality of partial regions are set within a scan region in which Doppler information is obtained. A partial scan operation is performed a plurality of times in a repetitive manner in each of the partial regions. In each partial region, a set of dummy transmitting and receiving beams is formed immediately before formation of the first set of transmitting and receiving beams. As the receiving beam in the first set of the transmitting and receiving beams is affected by the dummy transmitting beam, the receiving conditions can be unified over a plurality of sets of transmitting and receiving beams. A set of dummy transmitting and receiving beams may be provided immediately before the first partial scan operation or formation of a set of dummy transmitting and receiving beams in such a case may be omitted.

摘要： In an ultrasonic diagnosis apparatus, a first transmission signal including both of two fundamentals of frequencies f0 and 2f0 is transmitted, and then a second transmission signal having a polarity reverse that of the first transmission signal is transmitted. A receiving beam processor 22 generates a signal in which the echoes of the two transmission signals are added, and a signal in which the echoes are subtracted. The fundamental components are canceled out by addition and a secondary harmonic component A2 generated by the non-linear interaction remains in the sum signal. In the subtraction signal, the fundamental component remains while the secondary harmonic component is canceled out by subtraction. The fundamental component AII of the frequency 2f0 is extracted from the subtraction signal, and a ratio (A2/AII) is calculated by a divider 44. A differentiating process is then executed by an HPF 46 to obtain the evaluation value reflecting the non-linear parameter at each depth of the body.

摘要： A sample pretreatment system is equipped with a label sticking apparatus for sticking labels on containers. In this system, a manipulator 72 grasps and holds a container before label sticking from the pipetting apparatus to convey it to a receiving position on the line L-L along with the raising/lowering path of a container holding device 82. The container holding device 82 is raised by the raising/lowering mechanism 86 to be positioned at a receiving position in a complexly opened state. After receiving the container, the container holding device 82 is lowered, and then the container holding device 82 carries out the closing operation according to the lowering motion, thereby enabling to hold the container reliably irrespective of the diameter of the container. At the label sticking position which is set at a lower position, a label is stuck to the container. Then, the container holding device 82 is raised, and the transfer mechanism 83 rotates the labeled container which has been raised to the buffer position on the line B-B for a temporally evacuation. This sample pretreatment system makes it possible to handle containers of various diameters and carry out efficient container conveyance and label sticking with a simple structure.
