Abstract: A system and method to remotely enable software based options for a trial period in remote equipment is disclosed. The invention includes receiving and authenticating a user, and receiving an option-enabling request from the user specifying the particular option requested to be enabled in a particular piece of equipment at a remote location. A system I.D. is validated, and the system ensures that the option has not already been enabled at least once before, and if it has not, a software enabling key is generated and sent to activate the option in the remote equipment.

Abstract: The present invention relates to a method and apparatus for reducing metal artifact in image reconstruction. In at least one embodiment, the method for reducing metal artifacts in image reconstruction comprises collecting at least one uncalibrated image (an X-ray or fluoroscopic image for example) and calibrating the at least one uncalibrated image, forming at least one calibrated fluoroscopic image. A patient to transmitter transform is computed using at least the at least one calibrated image. A reconstructed volume is formed using at least a patient to transmitter transform. At least two of the at least one calibrated fluoroscopic image, the patient to transmitter transform and the reconstructed volume may be combined, forming at least one display image. This image may then be displayed, using a display device for example.

Abstract: A system and method are disclosed for providing access over a computer network to system documentation at an online central service facility. A user is required to enter identifying indicia prior to accessing the online central service facility, the facility having at least one documentation database containing product and/or service data therein. The identifying indicia can include a user identification and a password, for example, and are matched with user data stored in a user database in the online central service facility to authenticate the user before providing user access into a document management system. Also, the user is checked to further determine what particular product and/or service data the user is entitled to. Such particular product or service data is then delivered to the user.

Abstract: A method and a system for delivery of protected software applications to remote systems from a central service facility wherein delivery is managed on the basis of the community membership of the remote system user. Business rules are utilized to determine whether a particular authenticated user seeking access to a protected software application from a particular remote site should be authorized. A multiplicity of web servers are programmed to allow selective access to one or more resident software applications by remote system users via a network. Access is managed by a central policy server based on user and system information and community definitions stored in a database. The policy server communicates with each web server via an agency module incorporated in the web server. The agency module intercepts requests for access from remote system users and then interfaces with the policy server.

Abstract: A graphical image display provides improved image presentation due to potential removal of background data which would otherwise degrade presentation of the region of interest and due to automatic adjustment of image brightness and contrast based on operator preference. Statistical analysis of the image data is employed. The invention is particularly useful in medical diagnostic imaging.
