| 20090193893 | ANGULAR VELOCITY SENSOR - Provided is an angular velocity sensor including: a reference vibrator supported so as to generate reciprocating rotational vibration about a first rotation axis as a center; a detection vibrator supported by the reference vibrator so as to generate reciprocating rotational vibration about a second rotation axis, which is different from the first rotation axis, as a center; a reference vibration generating unit for allowing the reference vibrator to generate reciprocating rotational vibration; and a detection unit for detecting a displacement amount of the detection vibrator with respect to the reference vibrator, which is in association with the reciprocating rotational vibration of the detection vibrator. | 08-06-2009 |
| 20090299185 | DIAGNOSTIC ULTRASOUND APPARATUS - A novel diagnostic ultrasound apparatus has a plurality of ultrasound probes | 12-03-2009 |
| 20100043546 | SENSOR AND METHOD OF MANUFACTURING THE SAME - Provided is a sensor including a movably supported movable element and an opposing member. The sensor detects a relative positional relationship between the movable element and the opposing member which are provided with a spacing therebetween The opposing member has an impurity-doped portion which is provided to one of an opposing portion which is opposed to the movable element and an adjoining portion which adjoins the opposing portion. At least a part of the impurity-doped portion is formed on an opposite surface opposite to a surface which is opposed to the movable element, from which opposite surface an electrical wiring is led out. | 02-25-2010 |
| 20110083511 | SIGNAL PROCESSING APPARATUS, ULTRASONIC APPARATUS, CONTROL METHOD FOR SIGNAL PROCESSING APPARATUS, AND CONTROL METHOD FOR ULTRASONIC APPARATUS - A signal processing apparatus scans a beam of elastic waves into an object to be examined, acquires received waveform data of a plurality of scan lines, and performs signal processing to form a tomographic image of said object to be examined from the received waveform data of the plurality of scan lines. The signal processing apparatus includes a scan line correlation calculation part ( | 04-14-2011 |
| 20110098568 | IMAGE FORMING METHOD USING ULTRASOUND AND ABERRATION CORRECTION METHOD - An ultrasound image forming method comprises a first step of receiving a first signal reflected from the object, a second step of obtaining an aberration correction value based on the first signal thus received, a third step of receiving a second signal reflected from the object when a second ultrasound corrected based on the aberration correction value is transmitted to the object, and a fourth step of forming an image from the aberration correction value and the second signal. The center frequency of the second ultrasound is between 0.5 MHz and 20 MHz, the center frequency of the first ultrasound is between 3/16 and 9/20 of the center frequency of the second ultrasound. By this method, an accurate aberration correction value can be obtained and an ultrasound imaging with high resolution can be achieved even if aberrations are large and difficult to correct. | 04-28-2011 |
| 20110187868 | ACOUSTIC-WAVE SENSOR, ACOUSTIC-WAVE SENSOR ARRAY, AND ULTRASONIC IMAGING APPARATUS - An acoustic-wave sensor ( | 08-04-2011 |
| 20110208035 | SUBJECT INFORMATION PROCESSING APPARATUS - Generally, a photoacoustic signal has a wavelength longer than a general ultrasonic signal. That is, it does not matter even if at the time of acquisition of the photoacoustic signal, an element pitch of a probe is several times as large as at the time of acquisition of the ultrasonic signal. Thus, at the time of acquisition of the photoacoustic signal, a plurality of neighboring elements in a receiving element array are collectively considered as one element, and a phasing process is performed. As a result, the same effect as a plurality of phasing addition circuits are disposed in parallel is obtained, and not only a phasing addition process of the photoacoustic signal but also image reconstruction can be performed in real time at a high speed. | 08-25-2011 |
