    Abstract: A detector drawer for an X-ray detector has at least one stop (5) by which the mobility of an inserted X-ray detector in at least one direction is restricted. The mobility of the inserted X-ray detector is hindered by the at least one stop to two alternate stop positions with respect to that direction; and that the respective stop position becomes operative as a function of the motion of the X-ray detector upon its insertion, for instance as a function of the direction of the motion. By using the alternate stop positions, which automatically become operative, portable digital X-ray detectors, which are constructed asymmetrically, are automatically positioned centrally in the detector drawer regardless of their orientation or the desired orientation of the image to be made. The detector drawer is advantageously used in an X-ray system, and desirably in an X-ray system with a detector that is pulled out from opposite sides of a patient examination table.

  • Patent number: 6940948
    Abstract: In order to provide an improved X-ray imaging quality an X-ray detector (14) is equipped with means (13, 15) for orienting it towards an X-ray source (2) during a scan (8a, 8b, 27). Means (9, 10, z) for reorienting a housing (10) comprising the X-ray detector (14) and a conventional cassette holder (4) and detector positioning means (9-12) cooperate to receive an X-ray beam (26a) with improved collimation quality. Thus the detection efficiency is increased, the image resolution is enhanced, and the beam exposure of patients (5) can be minimized. Embodiments relate to a linear X-ray detector (14) designed for a serial readout of image pixels, a collimator (3, 3a, 3b) for both scanning and wide-perture X-ray imaging, and a supporting arm (9) carrying the X-ray source (2), collimator (3) and detector arrangement (17).

  • Patent number: 6926441
    Abstract: An articulated x-ray table comprises a planar, rigid radiolucent top support and a base spaced therefrom to form a gap whereby radiographic plates can be inserted and withdrawn. The gap is maintained by the use of one or more trolleys that are moveable along the length of the table to be moved into proximity to the location where the plate is to be inserted. Generally, two of the trolleys are used along either side of the table for placement near the x-ray plate. The trolleys move in grooves or tracks on the edges of the base along the length of the table. Each trolley includes wheels that engage the grooves, and a separate roller that engages the top support. This permits the trolleys to be easily moved along the guide notwithstanding the weight of a patient on the table. The table can be used for animals and humans.

  • Patent number: 6899458
    Abstract: A subject table for a mammography apparatus has a slot for an X-ray film cassette extending therethrough, as well as a locking mechanism for the cassette arranged in the slot. The locking mechanism has a spring-loaded arm carrying a first detent, and a second detent, at least one of the detents being spring-loaded such that the detents lie tightly against the narrow sides of the cassette when a cassette is introduced into the slot. For simplified removal or replacement of a cassette, the arm is displaceable in its longitudinal direction, and the second detent is displaceable perpendicularly to the longitudinal direction of the arm. When the second detent is removed from the cassette by an operating manipulation, the spring loading of the first detent causes the cassette to be ejected from the slot to a sufficient extent to allow it to be grasped by the operator.

  • Patent number: 6862762
    Abstract: The patient support apparatus includes a base frame and a patient support assembly. The patient support assembly is pivotably mounted the base frame and is moved by a first actuator to rotate between a horizontal position and an upright position. The patient support assembly includes an upper body portion, a lower body portion and a leg portion. The upper body portion, the lower body portion and the leg portion are pivotably interconnected with a linkage frame so that they can be moved in unison by a second actuator between a supine configuration and an upright, chair shaped configuration. Thus, the patient support apparatus is adjustable between a flat, bed shaped configuration and a seat shaped configuration and is also movable between a horizontal position and an upright position.

  • Patent number: 6811311
    Abstract: A patient support comprising a frame 22 supporting a translucent support surface 24 elevated above the frame 22 by frame members 23. The members 26 support an x-ray cassette tray 36 for sliding movement along the length of the frame 22. The x-ray cassette trays 36 can be loaded onto the members 26 from either or both the head 30 and foot 32 ends of the frame 22. All of the patient support surface can be covered by the x-ray cassettes. In use, the x-ray cassette tray 36 is pulled out from the members 26 and loaded with an x-ray cassette 53. The handle 39 is pulled out from within the tray 36 and locked into position against latch 38. The tray 36 is then slid back onto the members 26 and the position of the cassette 53 within the tray 36 is indicated by the position of the indicator 65 visible along the side of the frame 22.

    Abstract: A plurality of radiation images of an object is taken in different imaging positions. An area sensor which detects a radiation passing through the object is moved in a direction substantially parallel to the optical axis of the radiation. That the area sensor reaches one of the imaging positions is detected and the radiation is projected onto the area sensor only when the area sensor is in one of the imaging positions.

  • Patent number: 6276827
    Abstract: In a cassette tray for radiography, a positioning plate is provided on a rear surface of a tray, and the positioning plate includes grooves corresponding to cassette sizes. A stopper for holding a cassette has a spring, and engaging pieces which engage the groove and formed at a lower end of a slider moving vertically between a front plate of the tray and the positioning plate. When the engaging pieces of the stopper engage the grooves, the stopper projects from the front surface of the tray to hold the cassette at the position. When the engaging pieces of the stopper do not engage the grooves, the stopper is located on the same plane as the front plate surface of the tray. If the stopper is pressed and moved along the surface of the tray, the position for the cassette to be used can be selected. Accordingly, the cassette tray can securely hold various-sized cassettes, and the attaching operation therefor can be carried out easily in a short period of time.
