Ultrasonic probe for scanning a volume
First Claim
Patent Images
1. An ultrasonic swing probe for providing volume information with respect to a body organ, said probe comprising:
- a probe housing including an acoustic window enabling transmission of ultrasound energy therethrough;
an array transducer disposed within the probe housing and having a front face;
an undivided lens member includinga front focusing lens disposed on the front face of said array transducer, andan extension membrane portions which extends from front focusing lens, which is made up of a same material as that of said front focusing lens, and which has a periphery sealed to said probe housing to form a hermetic cavity filled with a coupling fluid; and
a drive means for providing a swinging movement of said array transducer.

Abstract
An ultrasonic imaging probe is provided which is capable of capturing “on-the-fly” scanning planes in successive positions of the probe so as to form a volumetric image representation at a real time frame rate. The probe includes a flexible sealing membrane for a coupling fluid. Laterally extending folding portions of the flexible membrane provide fluid isolation and cancellation of parasitic constraining forces normally generated during probe movement.
