Abstract: A system and method for non-invasive and quantitative assessment of the status of bone tissue in a bony member within a living organism are provided. In one embodiment, the system includes a transducer and a controller that causes the transducer to generate a pair of axial ultrasound signals traveling in opposite directions along a longitudinal axis of the bony member and a radial ultrasound signal traveling towards and into the bony member. The transducer receives multiple portions of each of the axial ultrasound signals and multiple portions of the radial ultrasound signal reflected by the bony member and generates axial and pulse-echo output signals in response. The controller processes the axial and pule-echo output signals to obtain an axial transmission time delay and a pulse-echo time delay, respectively, and generates an estimate of a characteristic of the bone tissue responsive to the axial-transmission and pulse-echo time delays.

Abstract: A magnetic key chain which provides for the ability to attach itself to a magnetic material, such as the inner surface of a front door of a home or a refrigerator door. The magnetic key chain also allows for therapeutic treatment of an anatomical site in a living body. In another embodiment, magnetic jewelry is adapted for both ornamental and therapeutic use.
