| 发明名称 | Device for calibrating and testing echotomographic equipment | ||
| 摘要 | A device for calibrating and testing echotomographic equipment comprises an electric motor, a pair screw—female screw, wherein the screw is connected to an outlet shaft of the motor and the female screw is mobile with respect to a supporting plane, so as to transform a rotary motion of the motor shaft into a linear motion, a piston connected to the female screw and linearly mobile, coherently to the female screw, a membrane stressed by the piston, means apt to allow propagating ultrasound waves towards/from said membrane. | ||

| 主权项 | 1. A device for calibrating and testing echotomographic equipment comprising: an electric motor; a pair screw—female screw, said screw being connected to an outlet shaft of the motor and said female screw being mobile with respect to a supporting plane, so as to transform a rotary motion of the shaft of the motor into a linear motion; a piston connected to said female screw and linearly mobile, coherently to said female screw; a membrane stressed by said piston; means for allowing propagation of ultrasound waves towards/from said membrane, and means for detecting a linear position of said female screw and piston. | ||
