Systems and methods for determining body composition by combining dual-energy x-ray (DXA) technology with three-dimensional (3D) optical technology and/or bioimpedance technology. A multi-modality scanning system may include a dual-energy x-ray source and an x-ray detector mounted to opposing sides a c-arm and configured to scan a patient on a optically translucent table. The system may also include one or more 3D optical imaging devices to capture 3D optical images of the patient substantially concurrently with the emission of the dual energy x-rays. A bioimpedance machine may also be included in the multi-modality scanning system. Data based on the dual-energy x-rays may be combined with the data from the 3D optical images and/or the bioimpedance data to generate values of at least three compartments selected from: bone, fat tissue, lean tissue, dehydrated lean tissue, and water.

Multiple modality body composition analysis

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.

Embodiments relate to display of visual content on a client device using server-side rasterization of visual content. According to some embodiments, visual content is rendered on a server system, transformed into bitmaps compatible with the display attributes of a client device, and transmitted for display on the client device. The server system can perform, in effect, as a remote browser for displaying Web pages, e-mail, e-mail attachments, electronic document and forms, database queries and results, drawings, presentations, images at the client device, and so on. The approach can be 'remote' because the server does the rendering and the client provides the interface; 'multi-level' because rendered visual content is represented as a multi-level set of raster representations; and constitutes a &#x201c;browsing system&#x201d; because the client and server share data about the source visual content element being browsed, and the client performs a specific browsing function assisted by the server.

In DEXA (dual energy x-ray absorptiometry), a system for automatically or nearly so identifying a region of interest in an AP (anterior/posterior) spinal image by processing the pixel values within a global region to find the lateral extent of the vertebra and the spaces between vertebra, and further processing the pixel values within the region of interest to derive estimates of bone parameters. In addition, also in DEXA, a system for automatically locating regions of interest in the hip.

A method of generating medical information including quantitative and image data, comprising steps of performing an image acquisition of at least a portion of a patient to be examined, generating image data based on the performed acquisition, generating quantitative data based on the performed acquisition and constructing a DICOM compatible file, the image data being provided in an image data field and the quantitative data being provided in another field of the DICOM compatible file.

Visual content browsing using rasterized representations

The present invention relates to display of visual content on a client device using server-side rasterization of visual content. Visual content is rendered on a server system, transformed into bitmaps compatible with the display attributes of a client device, and transmitted for display on the client device. The invention allows the server to perform, in effect, as a remote browser for displaying Web pages, e-mail, e-mail attachments, electronic document and forms, database queries and results, drawings, presentations, and images at the client device. The approach is &ldquo;remote&rdquo; because the server does the rendering and the client provides the interface; &ldquo;multi-level&rdquo; because rendered visual content is represented as a multi-level set of raster representations; and constitutes a &ldquo;browsing system&rdquo; because the client and server share data about the source visual content element being browsed, and the client performs a specific browsing function assisted by the server.

A DEXA bone densitometer produces estimates of future fracture risk from a current fracture data derived from a lateral image of a patient's thoracic and lumbar spine taken in a single scan, typically with the patient on her or his side, and from numerical bone mineral density measurements.

Device and method for determining future fracture risk

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.

Method of assessing bone characteristics using digital 2-dimensional x-ray detector

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.
