Attached to a proximal end portion of a flexible cord of an ultrasound probe of an ultrasound examination system, to be introduced into a body cavity through a narrow guide passage, is a flexible wiring film which can be coiled into a helical roll of a narrow cylindrical shape extending along an axial extension line of the flexible cord at the time of passing same through the narrow guide passage. Formed on a surface of the flexible wiring film are a plural number of wire connection points for c...

Display of the results of non-destructive testing with a beam of ultrasonic energy is enhanced by exercising precise control over the horizontal sweep voltage which is applied to the deflection plates of a cathode ray tube on which the test information is displayed. The sweep voltage generator produces a sawtooth waveform which has a precisely selectable slope. The sawtooth voltage waveform slope may be adjusted by selecting the capacitance, which is charged from an adjustable constant current s...

The disclosure is directed to an apparatus for scanning an object with a beam of ultrasound energy and for formulating image-representative signals from the ultrasound reflected from the object. An ultrasound reflector is disposed in the path of the ultrasound energy, the reflector typically being disposed in a suitable fluid, for example water. The reflector is mechanically driven and means are provided for sensing the relative angular position of the reflector and for generating a first clock ...

A ring of transmitter and receiver transducer arrays circumscribes an object to be scanned. Semicircular wave fronts of ultrasound energy are propagated from different points around the ring of transducers by triggering the transmitter arrays in sequence. The reflected and transmitted ultrasound energy picked up by the receiver arrays is then electronically analyzed and a synthetically focused image corresponding to the scanned object is reconstructed on a display screen. Surprisingly high quali...

Ultrasound breast scanning and diagnosis is achieved by suspending the breast in a water pool, in which is immersed a wide aperture transducer/lens assembly. The water path is defined by two separate segments, an upper one, into which the breast is suspended, contained by a flexible sonically transparent bag member, and the lower being contained in a longitudinally movable tank which is filled to contact with the bag member portion protruding into the tank.

A method and apparatus for the treatment of fabric materials with a liquid finishing agent such as a liquid repellant is disclosed. The method involves passing a strip of the fabric through a bath of the liquid finishing agent across a stationary fabric contacting surface. In the preferred embodiment, the fabric is subjected to ultra-sonic energy while immersed in the bath at a power level and frequency such that cavitation occurs in the bath adjacent the submerged material.

The invention provides a method of delivering ultrasound signals. The method includes providing an image of at least a portion of a subject intended to receive ultrasound signals between sources of the ultrasound signals and a desired region of the subject for receiving focused ultrasound signals, identifying, from the image, physical characteristics of different layers of material between the sources and the desired region, and determining at least one of phase corrections and amplitude correct...

In an ultrasonic sensor, including a housing having a plug connector, an ultrasonic converter, and a circuit board, the housing is divided into a support and a hood enclosing the support. The support carries the circuit board, the plug connector, and the ultrasonic converter.

The invention relates to an Ultrasound Sensor, especially for a vehicle and the passenger compartment thereof, comprising a can-shaped housing, a housing base, a housing closure and a sensor element arranged at the base inside the housing, and in the area of the housing closure there is arranged a contact device which is attachable, in locally fixed fashion, inside housing; the contact device presenting, in the direction of the longitudinal axis, a penetrating recess and being connected, in elec...
