Ultrasound probe for medical imaging system.

摘要

An ultrasound probe for a medical imaging system, comprising an ultrasound absorber (3) and a piezoelectric vibrator (1) mounted on the ultrasound absorber (3), and cut from the surface of the piezoelectric vibrator (1) to the ultrasound absorber (3) in the form of an array by a plurality of cutting grooves (6). A cutting depth d of each cutting groove (6) in the ultrasound absorber (3) is determined by an integer times a quarter of a wave length lambda corresponding to a center frequency f0 of ultrasound waves radiated from the piezoelectric vibrator (1). Consequently, symmetrical electro-acoustic conversion characteristics of the ultrasound probe can be obtained in the frequency domain.
