A mobile radiography apparatus has a wheeled transport frame and a sectioned vertical column mounted on the frame, defining a vertical axis and having a base section with a first vertical position relative to the vertical axis and at least a first movable section that is translatable to a variable vertical position along the vertical axis. A boom apparatus supports an x-ray source, wherein the boom apparatus is coupled to the first movable section for positioning of the x-ray source along the vertical axis and extends outward with respect to the sectioned vertical column for positioning of the x-ray source in a direction that is orthogonal to the vertical axis.

A storage phosphor reader apparatus for reading exposed storage phosphors. The reader includes an outer frame assembly including a cassette handling assembly for handling cassettes; an inner frame assembly; a first set of vibration isolators; a storage phosphor scanning assembly; and a second set of vibration isolators. A frame locker assembly is provided for locking the scanning assembly to the outer frame assembly when a cassette is transferred between the cassette handling assembly and the scanning assembly and for unlocking the scanning assembly during scanning of a storage phosphor removed from the cassette, so that the first and second sets of vibration isolators isolate the scanning assembly during storage phosphor scanning.

A storage phosphor reader includes a multicassette autoloader for vertically oriented storage phosphor cassettes, the autoloader having a front, back, and opposite sides. The autoloader includes an input bin for receiving multiple vertically oriented storage phosphor cassettes stacked together in face-to-face contact such that said cassette faces face front and back; wherein each of said cassettes contains a storage phosphor which is removable from said cassette; and an output bin located beside said input bin, said output bin having a storage phosphor read location at which a storage phosphor is removed from and replaced in a storage phosphor cassette positioned at said storage phosphor read location, and having an output region for read cassettes to be subsequently removed from said output bin.

A multicassette autoloader for vertically oriented storage phosphor cassettes includes a front, a back and opposite sides. The autoloader includes an input bin for receiving multiple vertically oriented storage phosphor cassettes stacked together in face-to-face contact, wherein the cassettes are oriented front-to-back with faces facing the autoloader sides, and wherein each of the cassettes contains a storage phosphor which is removable from the cassette; a storage phosphor read location at which a storage phosphor is removed from and replaced in a storage phosphor cassette positioned at the storage phosphor read location; and an output bin for receiving storage phosphor cassettes from the storage phosphor read location for subsequent removal. The input bin, the storage phosphor read location, and the output bin are configured in the autoloader such that the input bin and the output bin are side-by-side but spaced apart and the storage phosphor read location is positioned in a path between the input bin and the output bin.

A mobile radiography apparatus has a portable transport frame and a sectioned vertical column mounted on the frame and defining a vertical axis, with a base section having a first vertical position relative to the vertical axis and a top section and at least one intermediate section between the top section and base section, wherein the top and the at least one intermediate sections are translatable along the vertical axis to vary the height of the sectioned vertical column. A boom apparatus supports an x-ray source, wherein the boom apparatus is coupled to the at least one intermediate section for positioning of the x-ray source along the vertical axis and extends outward with respect to the sectioned vertical column for positioning of the x-ray source in a direction that is orthogonal to the vertical axis.

An x-ray cassette having increased durability. The x-ray cassette comprises a shell and a storage phosphor assembly. The shell comprises an upper and lower panel, a first and second side member, and a front end member. The first and second side members and front end member join the upper and lower panels to define a cavity having an open end. The storage phosphor assembly comprises a back end member, an insert plate, and an edge insert. The storage phosphor assembly is adapted to be removably contained within the shell such that the back end member closes off the open end of the shell. A first side of the edge insert is affixed to the insert plate. A first end of the edge insert is disposed adjacent the back end member, and a second end of the edge insert comprises at least one recess on the first side. In a preferred embodiment, the insert plate includes a honeycomb core comprising honeycomb cells wherein the honeycomb cells disposed along a perimeter of the honeycomb core are filled with an adhesive or epoxy.

A radiation image reading apparatus, including a cassette receiving section, a scanning section, an erase section, and a transport section. The cassette receiving section is adapted to receive a cassette housing a stimulable storage phosphor sheet. The transport section is adapted to transport the sheet along a substantially linear transport path to and from a travel end point in forward and reverse directions, respectively, through the scanning section and the erase section. The scanning section is coupled to the transport section and comprises: an excitation source for directing excitation energy of a first wavelength toward the sheet; a detector for receiving light excited from the sheet by the excitation energy; and a gimbaled mounting mechanism configured to register the scanning section to the surface of the sheet.
