ULTRASOUND PROBE AND ULTRASOUND DIAGNOSTIC APPARATUS INCLUDING SAME
First Claim
1. An ultrasound probe connected to a diagnostic device body, and for generating reception signals by transmitting and receiving ultrasonic waves and transmitting the generated reception signals to the diagnostic device body, comprising:
- a plurality of ultrasound transducers arranged in an array;
a plurality of transmission paths of the reception signals for transmitting to the diagnostic device body the reception signals generated by transmitting and receiving ultrasonic waves through the plurality of ultrasound transducers;
a plurality of impedance matching elements connected to the plurality of ultrasound transducers, respectively, each being disposed in each of the plurality of transmission paths of the reception signals, and each having a respective preset matching frequency, andwherein the plurality of impedance matching elements have a distribution in which a matching frequency of an impedance matching element becomes higher as an arrangement position of an ultrasound transducer corresponding to the impedance matching element in the array of the plurality of ultrasound transducers becomes closer to a center of the array, in order to reduce an influence of transmission/reception angles of ultrasonic waves due to the arrangement position of the corresponding ultrasound transducer in the array.

Abstract
The ultrasound probe includes ultrasound transducers arranged in an array; transmission paths of the reception signals; impedance matching elements connected to the ultrasound transducers, respectively, each being disposed in each of the transmission paths of the reception signals, and each having a respective preset matching frequency. The impedance matching elements have a distribution in which a matching frequency of an impedance matching element becomes higher as an arrangement position of an ultrasound transducer corresponding to the impedance matching element in the array of the ultrasound transducers becomes closer to a center of the array, in order to reduce an influence of transmission/reception angles of ultrasonic waves due to the arrangement position of the corresponding ultrasound transducer in the array.
