摘要： A method of measuring bone mineral density (BMD) of a selected region of bone in a small body portion (such as a limb or extremity), using a mini C-arm x-ray fluoroscopic imaging system to acquire the data from which the BMD is calculated. Apparatus for performing the method includes a tray for positioning the small body portion in the x-ray beam path of the imaging system and a sample of bone of predetermined density supported by the tray in side-by-side relation to the selected region of bone.

摘要： A method of calibrating an ultrasound bone analysis apparatus having a pair of transducer assemblies. Each transducer assembly has a transducer and a coupling pad, and is movable relative to the other so that a face of each pad can be moved to a position in which they mutually contact and to a position where the faces contact body parts. The method according to the present application includes transmitting an ultrasound signal from one transducer and receiving a signal corresponding to the transmitted ultrasound signal through the other transducer when the transducer assemblies are in the first position and the second position. A time for the ultrasound signal to pass through the body part is determined, and a width of the body part based on positions of the transducers is determined. Then, using the time and width values a speed of sound of the ultrasound signal passing through the body part with squish compensation is calculated.

摘要： Single and dual-energy x-ray images are obtained in a single scanning procedure, which allows measurement of bone density from the scan information acquired at both energy levels and high resolution digital geometric images from one of the two energy level scan sets. Densitometric and geometric measurements taken from multiple projections may be combined to create three-dimensional densitometric and tomographic images. An interface device allow an operator to select one of a plurality of scanning sequences which correspond to scanning a set of regions of interest in the patient.

摘要： A method and apparatus for communication in a wireless sensor network. In one embodiment, one or more routers in a network may be available for communication with one or more star nodes at a randomized time and/or frequency. A connectivity assessment, which may be performed at several different frequencies and/or times, may be performed to evaluate the quality of communications between devices in the network. Primary and secondary communication relationships may be formed between devices to provide for system redundancy. One or more proxies may be maintained where each proxy includes a status of one or more devices in the network, e.g., one or more star nodes or routers. Proxies may be used to handle information requests and/or status change requests, e.g., a proxy may be requested to change a communication relationship between devices in the network and may generate command signals to cause the corresponding devices to make the change.
