Abstract: An adjustable phantom (36) includes a base (202), an actuator (204) and a phantom (210). The phantom includes first (210a) and second portions (210b), each having a different value of a physical characteristic measured by a scanner (10). The phantom (210) is movable with respect to the base (202). In one embodiment, the phantom is well suited to simulating the arrival of contrast agent in a contrast enhanced imaging examination.

Abstract: A computerized tomography system includes a stationary section (A) and a rotating section electrically linked by at least one interconnecting slip ring (D). On one side the slip ring (D) is configured as a series of electrically conductive segments (20A-20H) separated by non-conductive interruptions (22A-22H). On the other side a like number of transmitters (26A-26H) is in selective electrical contact with the conductive segments (20) depending on a position of the rotating frame. Also included is a de-multiplexer (40) which takes image data from the plurality of receivers (RxA-RxH) and rearranges the image data in a determined sequence. Also shown is an angular encoder (46) for providing angular displacement signals (44) to the de-multiplexer (40) for assistance in reconstructing the data channels (30) in the determined sequence.

Abstract: An ammunition clip or magazine for a firearm including a self-contained system for sensing the amount of ammunition contained within the magazine and visually or audibly indicating that value to the user of the firearm. The counting and indicator system may be configured to display the number of rounds remaining in the magazine itself, or the number of rounds remaining in the firearm overall (the number of ammunition rounds in the magazine plus one round in the chamber of the firearm, if applicable), or it may be configured to simply indicate that the magazine is empty or that the number of rounds remaining in the magazine is below some other predetermined threshold. The magazine may be utilized in conjunction with any suitable firearm without modifying the firearm.
