用于检测动脉位置以测量血流速度的相控阵列
摘要：
一种用于检测动脉位置以测量血流速度的系统，包括第一压电换能器阵列，其包括多个换能器元件，所述换能器元件中的每一者支撑在第一陶瓷基底上，所述第一陶瓷基底具有被构造成放置在用户的皮肤区域的表面上的平坦的下表面，所述第一陶瓷基底被构造成将由换能器元件发射的超声信号耦合到皮肤；相位控制系统被构造成向换能器元件中的每一者供应电致动信号，所述电致动信号针对换能器元件中的每一者被相移。相位控制系统被构造成使供应到换能器元件的电致动信号相移以使得形成超声波束，并且使超声波束朝向位于皮肤区域下方的血管转向。
摘要（英）：

A system for detecting artery location to measure blood velocity includes a first piezoelectric transducer array including a plurality of transducer elements, each of the transducer elements being supported on a first ceramic substrate, the first ceramic substrate having a planar lower surface configured to be placed on a surface of an area of skin of a user, the first ceramic substrate being configured to couple an ultrasonic signal emitted by the transducer elements to the skin. A phase control system is configured to supply each of the transducer elements with an electrical actuation signal, the electrical actuation signal being phase shifted for each of the transducer elements. The phase control system is configured to phase shift the electrical actuation signal supplied to the transducer elements such that an ultrasonic beam is formed and to steer the ultrasonic beam toward a blood vessel located beneath the area of skin.
