摘要： A method and apparatus is disclosed for creating a single plane of reference, also referred to herein as a virtual image plane, as a function of image planes of individual segments of a reconstructed MRI image. In particular, in accordance with an embodiment of the present invention, such a virtual image plane is calculated by constraining the distance of all points in a reconstructed volume from a virtual image plane to be within a specific tolerance. More specifically, in accordance with another embodiment, a virtual image plane is calculated by minimizing the maximum distance of the plane from points in the composed volume, such as those points that are on the image planes of the individual segments. Calculating such a virtual image plane in this manner is advantageous in that it provides a single reference plane that is useful, for example, in making measurements associated with surgical procedures.

摘要： Disclosed is an image reconstruction method in a high-energy dual-energy CT system. The method comprises steps of scanning an objection with high-energy dual-energy rays to obtain high-energy dual-energy projection values, calculating projection values of base material coefficients corresponding to the dual-energy projection values on the basis of a pre-created lookup table or by analytically solving a set of equations, and obtaining an image of base material coefficient distribution based on the projection values of base material coefficients. The method provides a solution for reconstruction with high-energy dual energy CT technology and thus a more effective approach for substance identification and contraband inspection, thereby bringing a significant improvement on accuracy and efficiency in security inspection.

摘要： A clock offset between a client and a server is measured by: (a) the client sending a request to the server; (b) upon receiving the request in step (a), the server optionally sending a server acknowledgement to the client; (c) upon the client receiving the server acknowledgement in step (b) or directly, if no acknowledgement was used, each of the client and the server proceeding to concurrently exchange their respective timestamps with each other a multiplicity (n) of times, thus forming a multiplicity (n) of timestamp exchanges; and (d) determining a plurality of apparent forwards and backwards delays based on the multiplicity (n) of timestamp exchanges. The preferred apparent forwards and backwards delays are then selected based on the minimum values (for each direction) determined in (d) above. The clock offset between client and server is then determined based on the preferred apparent forwards and backwards delays.
