    摘要： An ultrasound probe includes: an ultrasound input/output unit to output a transmission ultrasound to a test object by a pulse signal; and a signal input/output unit to output a reception signal when the ultrasound input/output unit receives a reflected ultrasound from the test object, wherein the ultrasound probe is set so that a difference between maximum and minimum values of a group delay in a transmission/reception frequency band at -20 dB of the ultrasonic probe is equal to or less than 0.15 radian, the group delay being obtained from a phase difference for each frequency between the input pulse signal and the reception signal obtained from the reflected ultrasound of the transmission ultrasound output by the pulse signal, or so that a standard deviation of the group delay in the transmission/reception frequency band at -20 dB of the ultrasonic probe is equal to or less than 0.025.

    摘要： Even when electroacoustic conversion elements with high nonlinearity are employed, a nonlinear imaging is carried out with extracting more nonlinear components. An ultrasonic wave beam is transmitted twice from the transmitter to an identical position on the imaging target, and the signal processor performs computation on the reception signals obtained in every transmission performed twice, thereby extracting a nonlinear component included in the reception signals. In one transmission out of the transmission performed twice, the transmitter delivers the transmission signal to all of multiple electroacoustic conversion elements for driving the electroacoustic conversion elements, and in the other transmission, the transmission signal is delivered selectively only to a part of the multiple electroacoustic conversion elements for driving the electroacoustic conversion elements.

    摘要： The invention relates to a temperature distribution determining apparatus for determining a temperature distribution within an object caused by applying energy to the object. A temperature distribution measuring unit (6, 7) measures a spatially and temporally dependent first temperature distribution in the object (3), while the energy is applied to the object (3) such that the object (3) is heated to a temperature within a first temperature range, and a temperature distribution estimating unit (5) estimates a spatially and temporally dependent second temperature distribution in the object (3) within a second temperature range, which is different to the first temperature range, based on the spatial and temporal dependence of the measured first temperature distribution. Since temperature distributions can be obtained not only in the first temperature range, but also in the second temperature range, the overall temperature range, in which the temperature distribution can be determined, can be increased.
