A phantom for a quantitative ultrasound device is provided. The phantom includes a hollow casing, a first acoustic element disposed within the hollow casing, the first acoustic element simulating a broadband ultrasonic attenuation (BUA) of an exemplary bone; and a second acoustic element disposed within the hollow casing, the second acoustic element altering a speed of an ultrasonic signal transmitted through the phantom, the second acoustic element being disposed in-line with the first acoustic element. The phantom also includes a third acoustic element disposed within the hollow casing, the third acoustic element forming an acoustic coupling agent between the first acoustic element and the second acoustic element. A method of fabricating a phantom is also described herein.

Phantom for a quantitative ultrasound device

An electronic phantom and method for electronically controlling a phantom for a quantitative ultrasound device are provided. The electronic phantom includes a housing, a first transducer element within the housing configured to receive an ultrasonic signal from a quantitative ultrasound device and a second transducer element within the housing connected to the first transducer element. The second transducer element is configured to transmit a modified ultrasonic sound wave to the quantitative ultrasound device based on the received ultrasonic signal. The first and second transducer elements are positioned in a back to back configuration within the housing.

A thin film piezoelectric material employs an array of metallic backer plates to provide high output, non-resonant ultrasonic transmission and reception suitable for ultrasonic measurement and/or imaging.

Thin film ultrasonic transmitter/receiver

An ultrasonic transmission unit for an imaging/quantitative ultrasound device provides for coaxial transducer crystals which may be operated independently with a first crystal operated alone for quantitative measurement and the first and second crystal operated together to provide a broad illumination for imaging of structure.

A contained water ultrasonic densitometer employs pre-inflated bladders holding coupling fluid about ultrasonic transducers. The bladders in a relaxed state define a cavity smaller than the human heel so that when the heel is inserted, the bladders conform to the heel in a wiping action removing entrapped air.

A connector assembly for a thin film acoustic receiver array provides a spring support block having a plurality of holes each aligning one helical compression spring which serves as a conduit between a rear surface of the piezoelectrict film and a circuit card. The front surface of the film is supported against the force of the springs using an acoustically transparent material that may also provide matching between water and the piezoelectric film
