摘要： A processing unit calculates first displacement related information concerning a first direction of an object to be measured by using data in either one of an increase period and a decrease period of a force applied to the objected to be measured, among first received data received by a first ultrasonic probe. In addition, the processing unit calculates second displacement related information concerning a second direction of the object to be measured by using data in the same period as that used to calculate the first displacement related information, among second received data received by a second ultrasonic probe.

摘要： A sample moves, either naturally (as in the case of the heart) or by application of force, and its movement is measured. A processing unit calculates first displacement related information concerning a first direction of the object to be measured (the sample) by using data in either one of an increase period and a decrease period of the force applied to the objected to be measured, from data received by a first ultrasonic probe. In addition, the processing unit calculates second displacement related information concerning a second direction of the object to be measured by using data in the same period as that used to calculate the first displacement related information, from data received by a second ultrasonic probe.

摘要： 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.

摘要： A technology capable of reducing the influence of the noise overlapped in a long transmission line when accurately measuring weak beam current in an electron beam writing system and capable of accurately and efficiently measuring weak beam current in a beam writing system using multiple beams is provided. With using a switch for connecting and disconnecting an electron beam detecting device and a detected signal line, the electron beam detecting device is disconnected from the detected signal line to accumulate the detected signals in the electron beam detecting device during the beam current measurement. Simultaneously with the finish of the measurement, the electron beam detecting device and the detected signal line are connected to measure the accumulated signals. Also, in order to simultaneously perform the measurement method, a plurality of electron beam detecting devices and switches are used to simultaneously measure a plurality of electron beams with high accuracy.
