The apparatus includes a controller, which performs transmission processing, in which an ultrasonic wave is transmitted toward the subject including the region of interest by driving the probe, and received signal processing, in which frames are generated based on the probe's received signals representing the ultrasonic wave reflected from the subject including the region of interest, a number of times at mutually different times, thereby generating multiple frames, which selects at least two frames under measurement to be subjected to measurement from the multiple frames, which extracts measurable ranges, where the measuring processing can be carried out, based on respective received signals obtained from the region of interest represented in the at least two frames under measurement, and which combines those measurable ranges together to perform predetermined measuring processing on the region of interest.

Ultrasound diagnostic apparatus and ultrasound measurement method using same

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.

Ultrasound probe

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.
