摘要： A system is provided for remotely servicing medical diagnostic systems. The diagnostic systems may include a range of modalities and system types. A remote service facility may be contacted by the diagnostic systems, or may contact the diagnostic systems via a network link. Service requests, messages, protocols, data and log files, and so forth, may be transmitted between the diagnostic systems and the service facility. The service requests are handled by the service facility interactively with the medical diagnostic systems. The diagnostic systems are thereby apprised of the status of service requests, service reports, and so forth. A uniform interface and platform are provided for facilitating interactive communications of service requests and data between the diagnostic systems and the service facility.

摘要： A method for performing reference normalization for an image created by an imaging system. The imaging system includes a radiation detector array with a right and left edge. The method includes receiving a projection dataset created by the imaging system in response to a varying x-ray tube current. The projection dataset includes a view and predicted fluxes are calculated for the set of reference channels within the view. A right set of reference channels are located proximate at the right edge of the detector array and a left set of reference channels are located proximate to the left edge of the detector array. The method also includes calculating average actual fluxes for the sets of reference channels. Based on the predicted reference fluxes and the average fluxes, a reference correction value for the view is determined. The correction value is applied for the reference correction of the view.
