摘要： ¢ ! In pipetting apparatus of a blood sample the method of the present invention intends to increase rapidity of dilution when diluting a red blood cell component having a high viscosity. At step 212, a diluent is dispensed into a diluting container 66, and at step 213 the diluent is aspirated through a nozzle tip 36 containing therein a red blood cell component. Thus first stage of dilution is performed in the nozzle tip 36. At step 214, a mixed liquid in the nozzle tip 38 is dispensed, and at steps 215 and 216 aspiration and dispensation are repeated to complete the dilution (mixing).

摘要： An ultrasonic Doppler diagnostic apparatus usable for ultrasonic image diagnostics accurately de- :ermines and displays the velocity of moving reflec- :ive members within a subject under observation by ransmitting an ultrasonic beam into the subject and eceiving the echoes reflected by the moving reflec- :ive members. The apparatus comprises a memory or storing a first velocity distribution obtained from a first signal received from a given direction, and a rangential velocity calculator for calculating a tangen- :ial velocity distribution in a direction tangential to an arc of a scanned sector by comparing said first velocity distribution with a second velocity distribu- :ion obtained from a second signal received from a direction deflected by a small angle with respect to :he direction of the first signal. When the apparatus s to be adapted for determining velocity by the autocorrelation method, it is provided with a memory for storing a first autocorrelation signal output by an autocorrelator and a tangential velocity calculator for calculating the tangential velocity distribution from the first autocorrelation and a second autocorrelation having a slightly different angle of deflection.The vectorial velocity of the moving reflective body is determined from the tangential velocity obtained by the tangential velocity calculator so that it is easily possible to obtain accurate velocity information including movement direction information with respect to the moving reflective member without need of transmitting ultrasonic beams from two separated locations. The apparatus thus provides accurate and useful information for use in image diagnostics.

摘要： ULTRASONIC DOPPLER DIAGNOSTIC DEVICE An ultrasonic diagnostic device for measuring the velocity of blood flow within a living body comprises a receiver for amplifying a received wave in accordance with a logarithmic amplification characteristic and at least one inverse logarithmic converter which produces an output having an inverse logarithmic characteristic with respect to the input thereto. As a result, the device can carry out high-precision measurement of blood flow even when the component of the received wave corresponding to the blood flow is much smaller than a component of the received wave corresponding to the wall of the blood vessel or heart through which the blood is flowing.

摘要： ULTRASONIC DIAGNOSTIC APPARATUS An ultrasonic diagnostic device capable of the accurate real-time measurement and display of the amount of deviation in the velocity distribution of moving objects within a living organism. This apparatus represents an improvement on the ultrasonic diagnostic apparatus of the type wherein an ultrasonic pulse beam is repeatedly transmitted into a living organism at a fixed pulse rate and the reflected echoes are picked up, amplified and displayed, the improvement comprising a complex signal converter for converting a received high frequency signal into complex signals by mixing the received high frequency signal with a pair of complex reference signals which have frequencies that are integer multiples of the pulse rate and which are complexly related to one another, an autocorrelator for determining the autocorrelation of the complex signals, the autocorrelator having a delay time equal to an integer multiple of the pulse period, and a deviation determinator for determining the amount of deviation from the autocorrelation.

摘要： The medical instrument for radiating and receiving microwave energy is applicable to biological tissue. In the treatment of internal tumours such as cancer etc. it enables exact positioning and the maintenance of temp. within definite limits at the defined place within the body. The microwave reflector (24) provided forms a spheroid with two focal points (f1,f2). One focal point (f1) can be placed in the tissue to be examined or treated. A microwave aerial (26) is assigned to the other focal point (f2) for the radiation or reception of microwave energy. The aerial is connected to the microwave source. The tissue to be treated is arranged so that the focussed microwave energy impinges on it for appropriate hyperthermal therapy.

摘要： A computerized tomography device using an X-ray reconstructs a CT image of a sample and processes the CT image. Brown adipose candidate pixels are extracted based on a CT number of each pixel reconstructing the CT image. An erroneous pixel removal process is applied to the candidate pixels. In the erroneous pixel removal process, a boundary pixel removal process, a contraction and expansion process, or the like are applied. With this process, only the brown adipose pixels are extracted. An amount of brown adipose is determined from the brown adipose pixels and an evaluation value such as a brown adipose percentage is calculated based on the amount of brown adipose and amounts of other tissues.
