Abstract: An ultrasound probe which is connected to an ultrasound diagnosis apparatus includes an acoustic element for converting an electric signal and an ultrasound to each other, an electric signal processing circuit electrically connected to the acoustic element, a case for storing the acoustic element and the electric signal processing circuit, an acoustic element board for electrically connecting the acoustic element to the electric signal processing circuit, and a partition part which is arranged to contact with the case and separates the acoustic element and the electric signal processing circuit. A space on the side of the acoustic element in the case separated by the partition part is filled with a first material having lower thermal conductivity than that of a material for forming an inner wall surface of the case. Accordingly, the heat generated by a circuit unit such as the electric signal processing circuit can be more efficiently dissipated.

Abstract: An ultrasonic diagnostic apparatus includes a controller, to which a probe and a monitor are connected, the probe having an array of transducers, in which a number of transducers are arranged in a first direction. The controller controls transmission of an ultrasonic beam using the array of transducers and reception of an echo signal reflected from a region of interest, generates image data based on the echo signal, and gets echo signals received from multiple points of the region of interest by either moving or swinging the array of transducers in a second direction that intersects with the first direction at right angles. If the sum of image data ranges of measured value retrievable portions of the region of interest at the multiple points synthesized based on the echo signals, is equal to or greater than a predetermined value, the controller calculates a detected value of the region of interest.

Abstract: A beam forming and adding unit receives an echo signal containing reflection by a side lobe of an ultrasonic pulse, and executes its focusing. A fundamental wave BPF unit and a fundamental wave detecting unit extract a fundamental wave component from the echo signal, and calculate its signal power. A harmonics BPF unit and a harmonics detecting unit extract a harmonics component from the echo signal, and calculate its signal power. A ratio calculating unit and a ratio comparing unit calculate a ratio of these two calculated signal powers, compare this power ratio with a power ratio threshold value stored in a reference memory, and notify its comparison result to a detection signal suppressing unit. The detection signal suppressing unit suppresses the echo signal according to the notification result, and outputs the echo signal. A display unit generates and displays an ultrasonic image based on the output echo signal.
