ABSTRACT:
Medical diagnostic X-ray table assembly including an X-ray source and detector. The entire assembly is mounted on a cantilevered horizontal transverse pivot for being raised and lowered or tilted as a unit. The table assembly is mounted eccentrically to the horizontal transverse pivot so the table can clear the floor when tilted to the foot down position, yet the table is low enough to be mounted easily by a patient.
The X-ray source and detector means are each supported by a series of superposed carriages driven by lead screw drives, thereby allowing the source and detector to independently translate transversely, longitudinally, and toward or away from the patient support. The X-ray source is also mounted on a transverse axis for being pivoted. A novel hydraulic mechanism is provided for tilting the table.
The table is versatile, as it can be used for a wide range of radiographic and fluorographic studies and does not require wall mounted or ceiling mounted auxiliary equipment to perform chest X-rays and other procedures not possible with conventional freestanding X-ray tables.
