Abstract:
1. An ultrasonic probe, comprising: an ultrasonic transducer section having a plurality of ultrasonic transducers, wherein ultrasonic waves are transmitted to a subject to be examined and reflection waves are received from said subject to be examined; a low attenuation medium; a convergence component that converges ultrasonic waves; a probe shell; and a puncture needle guide in said low attenuation medium, said puncture needle guide being configured to guide a puncture needle into said subject to be examined in a direction perpendicular to the contact surface side, wherein said probe shell is configured to house said low attenuation medium, said convergence component, and said ultrasonic transducer section in order therein, said ultrasonic transducer section transmits the ultrasonic waves to said subject to be examined and receives the reflection waves from said subject to be examined through said convergence component and said low attenuation medium, and a thickness of said low attenuation medium in a transmission/reception direction is set to exceed a required distance from a probe surface so that a stable and uniform sound field distribution of the ultrasound waves is formed near the probe surface.
