Title:
超音波撮像のための高調波発生可能な二次元(2D)アレイ
Document Type and Number:
Japanese Patent JP2006524531
Kind Code:
A
Abstract:
A two-dimensional (2D) array transducer capable of transmitting ultrasonic energy in tissue at a fundamental frequency and of sufficient power to generate a harmonic of the fundamental frequency. In particular, the invention requires that at least 25% of the array elements are excited to transmit the ultrasonic energy, that the transducer array has a checkerboard pattern, that high voltage electronics are housed in a transducer handle, that transmit and receive beamforming electronics are housed in a transducer handle, that high voltage electronics connected to transmit elements in the transducer and low voltage electronics connected to receive elements in the transducer are housed in the transducer handle, and that elements forming the array are of a single crystal.
