    摘要: A beam former for a ultrasonic diagnostic apparatus is arranged to have low-bit analog-to-digital converters and enables to obtain an excellent echo signal from blood flow. The beam former further includes a sample and hold circuit for sampling an echo signal of a pulse reflected from the inside of a human body. A delaying circuit serves to delay the output of the sample and hold circuit by a delay time corresponding to an integer multiple of a transmitted pulse period and is subtracted from the output of the sample and hold circuit. The subtracted output is analog-to-digital converted and is stored in a memory. The memory reads out the data asynchronously with the storage. The delaying circuit is composed of an analog-to-digital converter, a memory and a digital-to-analog converter and has a delay time corresponding to an integer multiple of the transmitted pulse period.

    摘要: An ultrasonic diagnostic apparatus includes a transmitting section that generates a drive signal to drive a probe in order to transmit an ultrasonic wave toward a subject to be deformed periodically under stress. A receiving section receives an echo, produced when the ultrasonic wave is reflected from the subject, at the probe to generate a received echo signal. A computing section determines a thickness change waveform, representing a variation in distance between two arbitrary measuring points on the subject, based on the received echo signal. A reference waveform generating section outputs a reference waveform. The apparatus obtains a subject's internal information by comparing the thickness change waveform and the reference waveform to each other.

    摘要: For heating or cooling a sample contained in a vessel portion through a heat transfer member held in contact with the vessel portion, there is used the vessel portion, which has a part formed of an elastic member, expands and contracts for injection and discharge of the sample, is closed other than a connecting port with a channel connected to the vessel, and expands and contracts for injection and discharge of the sample. The vessel portion expands correspondingly to the injection when the sample is injected through an inflow path serving as the channel into the vessel portion contracting in a non-contacting state with the heat transfer member. A predetermined amount of sample is injected into the vessel portion so as to expand the vessel portion, and the vessel portion comes into contact with the heat transfer member. The vessel portion is heated or cooled through the heat transfer member.

    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: 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.

    摘要: An object of the present invention is to provide a visual training apparatus in which a trainee can make accommodation of the trainee's eye easily when the trainee is training. 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.
