Problems solved by technology

This severely limits the choice of available fluids and complicates the design of such systems
In addition, the aforementioned coupling methods are heavy, dirty, and leaky, factors that limit the utility of such systems in clinical settings
Most of them also rely on gravity to contain the fluid, thus restricting the compression plate from pointing horizontally, which precludes lateral or oblique compression of chest tissue options

Embodiment Construction

[0024] Thus, as mentioned above, ultrasound imaging has been used for many years to generate diagnostic images of the chest. Ultrasound systems have now been developed to produce three-dimensional (3D) images of the chest, unlike earlier systems. This is accomplished by scanning the chest with a moving array transducer. Array transducers emit and receive electronic guidance beams that scan a target plane without moving the transducer. As the array transducer moves in the vertical direction, it successively scans a planar sequence. These planes would be thought of as analogous to many playing cards aligned in a pile. Each playing card plane is a planar image, and many cards include a plurality of planar images aligned in parallel of three-dimensional objects. The data of this planar sequence will be used to render a three-dimensional (3D) image, as is known in the art.

[0025] In order to accurately scan the chest with a moving transducer, it must be stationary while the c...

Abstract

The present invention relates to a transducer unit for an ultrasonic breast imaging system, in which an acoustic coupler is employed which comprises a frame in which a transducer is mounted. The frame is open at one end, and a surface of the transducer is exposed at the open end. The frame and exposed transducer surface are put under compression against the surface of a compression plate with a gasket, or similar, providing a fluid-tight seal therebetween. A thin layer of acoustic couplant is provided between the transducer surface and the compression plate. The frame defines a chamber around the nonexposed surface of the transducer, the chamber housing an acoustic couplant.

Description

technical field [0001] The present invention relates to an acoustic coupler for use in a transducer assembly of an ultrasound imaging system, and more particularly to a transducer assembly particularly suitable for use in an ultrasound chest system arranged and constructed to obtain compressed chest Ultrasound scans for chest assessment and / or additional ultrasound chest imaging or other occasions where reliable and reproducible 3D chest ultrasound data are required. Background technique [0002] Ultrasound imaging has quickly become the preferred form of non-invasive study of human tissue. In particular, ultrasound imaging has been used for many years to produce diagnostic images of the chest. For example, US patent 4298009 describes a chest scanning apparatus consisting of a patient table on which the patient lies face down. The patient table has an aperture through which the patient suspends the chest into the sink below the table. At the bottom of the tank, an ultraso...
