摘要： The present invention enables ultrasonic propagation time values after correction of refraction to be calculated in parallel for each receive channel, by using a recurrence relation in the depth direction. Moreover, accumulation of errors can be avoided by using an accurate propagation time value obtained in advance at a reference depth to correct the propagation time value each time the reference depth is reached. For this error correction, the recurrence relation to calculate the propagation time value can be an approximate expression. For example, the propagation time value can be calculated using the inclination of reference propagation time values between reference depths. In an actual circuit, received signals are sequentially stored in a memory, and a receive beam is formed by calculating an address position corresponding to the propagation time value of the ultrasonic wave, and adding the received signals stored in the calculated addresses.
摘要翻译：本发明通过使用深度方向上的递推关系，能够对每个接收通道平行计算校正折射后的超声波传播时间值。此外，通过使用在参考深度预先获得的准确的传播时间值，可以在每次达到参考深度时校正传播时间值，可以避免错误的累积。对于该纠错，计算传播时间值的递归关系可以是近似表达式。例如，可以使用参考深度之间的参考传播时间值的倾斜度来计算传播时间值。在实际电路中，接收信号被顺序地存储在存储器中，并且通过计算与超声波的传播时间值相对应的地址位置，并将存储在所计算的地址中的接收信号相加来形成接收波束。

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.
