The present invention generally relates to a roller skate, and preferably an in-line roller skate having a foot platform suspended between front and rear wheels for increased stability. One feature the present invention is a retractable wheel positioned between the front and rear wheels. Another feature of the invention is a contoured toe piece removably attached to the foot platform and a heel piece pivotably attached to the foot platform. A still further feature of the invention is that the heel piece is slidable to allow the skate to accommodate shoes of various sizes. A still further feature of the present invention is its effective and easy to use streamline brake system.

An adaptive CT data acquisition system and technique is presented whereby radiation emitted for CT data acquisition is dynamically controlled to limit exposure to those detectors of a CT detector assembly that may be particularly susceptible to saturation during a given data acquisition. The data acquisition technique recognizes that for a given subject size and position that pre-subject filtering and collimating of a radiation beam may be insufficient to completely prevent detector saturation. Therefore, the present invention includes implementation of a number of CT data correction techniques for correcting otherwise unusable data of a saturated CT detector. These data correction techniques include a nearest neighbor correction, off-centered phantom correction, off-centered synthetic data correction, scout data correction, planar radiogram correction, and a number of others. The invention is applicable with energy discriminating CT systems as well as with conventional CT systems and other multi-energy CT systems, such as dual kVp-based systems.
