A method is provided for using assertions to reconcile records in a healthcare environment. Records are input, compared to a collection of previously input records and likelihood ratios indicating a probability of each input record match each of the collected records are calculated. The ratio is compared against two separate accept and reject criteria.

The global exception list is split among the sites that are part of the federation, so that each site receives a local exception list referring to patients records at that site. Each site evaluates each pair of records in its local exception list and makes an assertion stating for each pair of records whether they are a match or a mis-match. This assertions derived during the manual review is placed in a global exception list and are accessible by other members in a federation of users. An assertion becomes the truth for the site making that assertion.

LIQUID DROPLET INTERPROXIMAL CLEANING APPARATUS WITH GAS STREAM LIMITATION
The interproximal cleaning apparatus includes a gas reservoir (12) containing a compressed gas, such as CO2, in both liquid and gaseous states. A siphon tube (20) extends down into the liquid region of the gas reservoir when the apparatus is in an upright position. The siphon tube connects the reservoir to a metering valve (18) which has a metered volume to accommodate an amount of liquid compressed gas which is sufficient for good liquid droplet cleaning when it decompresses and forms a gaseous stream, without damage to the dental regions of the user. If the apparatus is severely tilted or turned upside down, gaseous CO2 or a combination of gaseous and liquid CO2 will enter the siphon tube and then the metering valve. The size of the metering valve will limit the volume of the gaseous CO2 to a safe amount, both when liquid CO2 or gaseous CO2 are applied to the metering valve.
The cleaning apparatus includes a source of gas under pressure (12) and a source of fluid (14), along with associated gas (26) and fluid (34) chambers, adapted for successive single uses. A user-operated metered valve (22) connects the gas reservoir to the gas chamber, while a liquid pump (30) and a one-way valve (32) connects the liquid reservoir to the liquid chamber. When gas is released from the gas reservoir, it expands rapidly from the valve into the gas chamber, resulting in pressure therein sufficient to open a one-way valve (34) connecting the gas chamber to the liquid chamber. The gas in the liquid chamber forces liquid therein through a liquid line (15) to a connecting point with a gas stream line (13) from the gas chamber. The interaction of the fluid with the gas stream results in a spray of liquid droplets (17) which are directed out of the gas stream line exit orifice (16) to the teeth for cleaning.

These measures are later combined into a statistical quantification of the target measure (FIG. 3). This information is presented (52) to the user to give the user possible outcomes of the radiotherapy plan, and, e.g., confidence levels in those outcomes.

A scanner (10) is used to provide images for automated diagnoses of neurodegenerative diseases, such as Alzheimer's disease. The images are registered (90) to a template (78). The aligned image is analyzed (60) in relation to reference image data (76, 80) which has been registered to the template which is contained in a knowledge maintenance engine (70) for similar patterns of hypo-intensity that would indicate (in the case of an FDG tracer) reduced glucose uptake in the brain. The most appropriate reference images for the analysis of the present study are chosen by a filter (74). The present study is then given a dementia score (84) as a diagnostic feature vector that indicates to a clinician the type and severity of the ailment based on the analysis. The scanner (10) can produce PET or other metabolic and MR images for diagnosis. The MR can be used to measure blood flow rate into the brain. From the blood flow rate and the metabolic image, tracer, e.g. FDG, uptake maps can be generated for use in the automated diagnoses.

Abrégé
In nuclear imaging, solid state photo multipliers (48) are replacing traditional photomultiplier tubes. One current problem with solid state photomultipliers, is that they are difficult to manufacture in the size in which a typical scintillator is manufactured. Resultantly, the photomultipliers have a smaller light receiving face (50) than a light emitting face (46) of the scintillators (44). The present application contemplates inserting a reflective material (52) between the solid state photomultipliers (48). Instead of being wasted, light that initially misses the photomultiplier (48) is reflected back by the reflective material (52) and eventually back to the radiation receiving face (50) of the photomultiplier (48).
A method for visualizing a region of interest within a viewport includes presenting tomographic image data as an image in a viewport using a set of global image processing operations, presenting a viewing window in the main viewport; and using a second, different set of image processing operations that is local to the viewing window, wherein the second, different set of image processing operations reduces image artifact with respect to a desired structure of interest in the viewing window.
A high percentage of preventable medical errors occur due to poor communication during the period when patient care is handed from one caregiver to another. Electronic annotations from patient specific body sensor networks are created and classified according to the caregiver and the urgency of the annotation to ensure that no information goes unnoticed during the transfer of care. Sensors (10) of each body sensor network store the annotations, and share the annotations with all the other sensors (10) in the network. The sensors (10) communicate wirelessly with a monitor (12), nurses station (14) a portable device (16) or other device (19) associated with a medical facility network to display the annotations for the caregiver on an associated display (12a, 14a, 16a, 19a). The caregiver can view, create, edit, and delete annotations with input devices (12b, 14b, 16b, 19b) as appropriate. The system can be applied in a hospital or care facility in which patients are monitored with a body sensor network based monitoring system. This includes ICUs, ERs ORs, preparation rooms, cathlabs, and diagnostic imaging rooms, as well as others.

When configuring a network system (10) in a user's residence, a patient to receive home healthcare assistance or other user receives an encoded configuration message. One type of configuration message includes a sequence of code words, each of which corresponds to one or more numerical digits, which the user receives via voice or text message on a mobile phone (28), as an email message, etc., and the user enters the codewords into a set top box (STB) (12). The user enters the codewords by selecting the codewords and/or images representing the codewords displayed on a GUI (18). The STB (12) uses a translation table (40, 42) to decode the codewords to determine the numerical sequences. The complete sequence represents a configuration information sequence, such as a user ID, an IP address, or the like, and is employed by the STB (12) to configure itself and/or other components in the network system (10). If the configuration message is received on a Bluetooth-capable cellular device, the configuration sequence is sent wirelessly to the STB (12).
