A PC board of a PC has a controller for controlling a motor drive circuit based on a timing signal, a memory for GAIN/STC for storing amplification data in an data in an amplifier for GAIN/STC as digital data and outputting the stored data synchronously with the timing signal of the controller, and a PC internal bus controller for connecting a PC internal bus to a local bus. Set values of GAIN and STC are converted into parameters and are set to the memory for GAIN/STC and a set value of contrast is converted into a parameter and is set to the controller both in a live state and in a freeze state.

Ultrasonic diagnostic apparatus and ultrasonic diagnostic method capable of adjusting gain and contrast

The ultrasonic wave diagnosing apparatus of this invention comprises a controlling circuit controlling the rotation, advance and retreat of an ultrasonic wave oscillator, a DC power source feeding an electric power to a DC motor rotating the ultrasonic wave oscillator, a DC motor controlling circuit inputting a controlling signal from the above mentioned controlling circuit and controlling the voltage of the above mentioned DC power source, a photointerrupter detecting the position of the ultrasonic wave oscillator by the advance and retreat, a stepping motor advancing and retreating the above mentioned ultrasonic wave oscillator and a record controlling apparatus controlling an auxiliary memorizing apparatus which can record an ultrasonic wave image obtained by the above mentioned ultrasonic wave oscillator so that, in order to reverse the rotation by inverting the phases of controlling signals A and B of the stepping motor advancing and retreating the above mentioned ultrasonic wave oscillator, a position detecting signal of the above mentioned photointerrupter is input into the above mentioned controlling circuit.

Ultrasonic wave diagnosing apparatus having an ultrasonic wave

In an ultrasonic probe for use in ultrasonic endoscope, ultrasonic diagnosing apparatus and other ultrasonic apparatuses, an ultrasonic vibrator is arranged in a recess formed in a cylindrical housing and is secured thereto such that portions of first and second electrodes are exposed out of the recess. First and second lead wires are embedded in the housing such that tips of the lead wires are exposed within connecting areas formed in the housing in communication with the recess. The tips of the first and second lead wires are connected to first and second electrodes of the ultrasonic vibrator with the aid of conductive members made of solder, conductive paste or conductive adhesive agent. The other end of the first and second lead wires are extended from the same end face of the cylindrical housing.

Ultrasonic probe

An ultrasonic observing apparatus includes an ultrasonic wave transmitting and receiving apparatus for transmitting and receiving ultrasonic waves, a first scanning apparatus for moving the direction in which the ultrasonic wave transmitting and receiving apparatus transmits and receives waves so that a first ultrasonic tomographic image may be obtained, a second scanning apparatus for moving the direction in which the ultrasonic wave transmitting and receiving apparatus transmits and receives waves so that a second ultrasonic tomographic image intersecting with the first ultrasonic tomographic image may be obtained and a control apparatus for controlling the first scanning apparatus and second scanning apparatus as related with each other.
