摘要： A small ultrasound diagnostic device is provided at a low cost that enables the appropriate control by a single power supply unit so as to give a predetermined transmission power to a driving waveform different for each mode without excess or deficiency and without affecting properties of the driving waveform. The ultrasound diagnostic device includes: an ultrasound generation unit (1) that transmits ultrasound; a waveform generation unit (2) that generates a single pulse or a burst pulse whose duty factor is variable in units of a time that is a period corresponding to a frequency outside a frequency band of the ultrasound generation unit (1) so as to drive the ultrasound generation unit (1); and a single power supply unit (3) that determines an amplitude of a driving waveform generated by the waveform generation unit (2). Thereby, an acoustic power of the transmitted ultrasound can be controlled without making the transmission amplitude variable.

摘要： An excellent ultrasonic diagnostic apparatus is provided that can form a three-dimensional image in a more spatially-correct position regardless of an ultrasonic probe to be used, without leading to deterioration of the productivity of the treatment. An ultrasonic probe includes an ultrasonic transducer, a rotation transmission mechanism, a rotary encoder, a transducer-swinging motor and an encoder correction ROM. In the encoder correction ROM, an actual swing scanning angle of the ultrasonic transducer with respect to each count value that is obtained by counting pulses from the rotary encoder is stored in advance. A three-dimensional image processing means forms a three-dimensional image of a principal cross-section scanning plane in a direction at the actual swing scanning angle, while correcting an encoder count value from an encoder counter according to contents of the encoder correction ROM that are read out by a main controlling means.

A radiation conductor is formed on one main surface of a substrate, and a ground conductor is formed on the other main surface of the substrate opposite to the radiation conductor. A feeding conductor is formed on the side surface of the substrate so as to extend from the other main surface toward the one main surface. The radiation conductor is formed into a square shape or an electrically square shape in a plan view. On the substrate, capacitive loading conductors are provided in the extended directions of the two diagonal lines of the radiation conductor, the capacitive loading conductors being formed between the ground conductor and the radiation conductor, and having mutually different shapes between the one diagonal direction and the other diagonal direction.
