摘要： A technology for performing the filter processing of blood flow velocity data having aliasing by only common filter processing means and common addition and subtraction means and actualizing image display of smooth blood flow velocity is disclosed. According to this technology, when performing image display of the blood flow velocity of blood within a subject biological body using an ultrasonic wave Doppler method, the difference values of data D33 of an arbitrary focus point and data D32 and D34 of points spatially prior and subsequent to this focus point are calculated in the pre-processing unit (difference calculating unit) 41. Then, in the filtering unit 42, after filter processing is performed on these difference values, data D39 after filter processing and data D33 of the arbitrary focus point are added in the post-processing unit (addition processing unit) 43. In this way, a filter processing can be performed under the assumption that the velocity difference is smaller than the velocity difference generated by the aliasing phenomenon, and filter processing of the blood flow velocity value in the sound ray direction of the ultrasonic waves can be performed without being influenced by aliasing.

摘要： The present invention aims at providing an ultrasonic diagnostic apparatus capable of displaying a stable spatial distribution of elastic characteristics for each heart beat without depending on the measurement of blood pressure and the accuracy or stability of such measurement, where an ultrasonic wave transmitted from an ultrasonic probe 13 and reflected by biomedical tissue is input to a computing section 19 by way of a receiving section 15, a delay time control section 16, phase detection section 17 and filter section 18. In accordance with the phase detection signal acquired from the phase detection section 17, the computing section 19 computes a relative elastic characteristic which is an elastic characteristic normalized by an elastic characteristic of an arbitrary reference area in the biomedical tissue. A distribution of relative elastic characteristics computed by the computing section is displayed on a display section 21.

摘要： A channel control mechanism for a microchip has a laminated structure formed of members including elastic members, and includes: a sample reservoir for packing a sample therein; a reaction reservoir in which mixture and reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other. The channel control mechanism performs the reaction and analysis in such a manner that the sample is delivered into the reaction reservoir through the channel. A shutter channel (pressurizing channel) is provided in a layer different from a layer in which the channel is formed so that the pressurizing channel partially overlaps the channel. The channel is closed through applying a pressurized medium to the shutter channel (pressurizing channel), and the channel is opened through releasing a pressure of the pressurized medium.

The visual training apparatus includes a display member 1, an optical system 2, a base 3 and a housing 4. The display member 1 displays a training image, and is fixed to the base 3 so as to cross an optic axis 51 of a trainee 5 substantially perpendicularly thereto. The optical system 2 includes a lens 21, a feed screw 22 and a motor 23. When the motor 23 is driven, the lens 21 moves along the optic axis 51 with the aid of the feed screw 22. Thus, the optical characteristic of the optical system 2 is changed so that the optical distance between the eye position of the trainee 5 and the display member 1 can be changed. The display member 1 displays a training image having dimensions proportional to the optical distance between the eye position of the trainee and the display member 1.
