Abstract: A method and apparatus are disclosed for obtaining an x-ray image from an x-ray imaging apparatus using a digital radiography receiver installs a retrofit connection apparatus that adapts the x-ray imaging apparatus for use with the digital radiography receiver by forming a receiver interface channel for communicating signals to and from the digital radiography receiver, forming an operator interface channel for routing at least an input expose signal from an operator control to the connection apparatus and forming a generator interface channel for transmitting at least an output expose signal from the retrofit connection apparatus to an x-ray generator of the x-ray imaging apparatus. An input expose signal over the operator interface channel initiates a reset of the digital radiography receiver over the receiver interface channel before the output expose signal to the x-ray generator is transmitted over the generator interface channel.

Abstract: A method for managing a portable x-ray detector for an x-ray imaging apparatus registers at least one portable detector with a processor that is associated with the x-ray imaging apparatus. A generated signal is indicative of the location of the registered portable x-ray detector relative to the x-ray imaging apparatus. An alert indication is provided when the generated signal indicates separation of the registered portable x-ray detector from the x-ray imaging apparatus beyond a predetermined distance.

Abstract: A scanning apparatus for obtaining an image from a phosphor sheet has a cylindrical drum having an inner axis and having an inner surface that is concave with respect to the axis. A light collector is coupled to a transport mechanism that is actuable to translate the light collector along a direction parallel to the axis. The light collector has a beam generator with a light source and a rotatable beam deflector that is actuable to provide a rotating scanning beam. There are first and second cylindrical hoops circumferentially disposed about the axis and spaced apart from each other along the direction of the axis to define a slot aligned with the rotating scanning beam as it scans the phosphor sheet. At least one light detector is disposed to detect light stimulated from the phosphor sheet by the scanning beam.

Abstract: A method for obtaining an x-ray image stores an association between a digital radiology receiver panel, a label that is applied to one or more surfaces of the digital radiology receiver panel, and an x-ray imaging room. A response to an operator instruction designates the digital radiology receiver panel having the stored association as an active digital radiology receiver panel in the x-ray imaging room. Instructions are transmitted wirelessly to the active digital radiology receiver panel. Image data is obtained from the active digital radiology receiver panel following exposure to x-ray radiation.

Abstract: A method for copy protecting a record carrier is disclosed, in which method the copy protected record carriers are provided with a pattern of logical errors which cannot be corrected by the error correcting rules predefined for said record carrier. The pattern of logical errors represents access control information. The logical errors are generated during decoding the bit sequence read from the record carrier. Bit errors may be positioned in the bit sequence so as to counteract de-interleaving which is part of an error decoding process in a reading device and accumulate in error words which are uncorrectable. Also a method for detecting access control information and a retrieval arrangement are disclosed, which retrieval arrangement serves to detect the access control information by selecting at least one error location, but not all error locations on the record carrier, and verifying the presence of an error by reading the selected error location via the reading means.
