Abstract

A mobile X-ray apparatus for use in X-ray in diagnostic examinations comprising a base on wheels having an arm structure mounted thereon for supporting an X-ray tube, wherein this arm structure comprises a first structure of telescopic construction utilizing a pulley principle for an extended vertical travel of the X-ray tube and yet compactness, and further including a constant spring mechanism for allowing manual positioning, a second structure moveably mounted on the first structure for both horizontal and vertical displacement of the X-ray tube which structure includes a parallelogram and a horizontal telescopic member, a steering assist mechanism including motors providing power to each wheel of one pair of the wheels and being independently energized so that a power differential can be created as desired to assist in turning the apparatus. This disclosure further includes a brake mechanism for effective control of positioning of any moveable structure of an X-ray apparatus.

Claims

1. A mobile X-ray apparatus for use in medical diagnostic examinations comprising:

a base comprising;

an X-ray generator,

a steering means,

a sensing means,

wheels supporting said bas and including at least one manually steerable wheel and one pair of wheels wherein each wheel is connected to a power means, and wherein;

said steering means are connected to the manually steerable wheel or wheels,

said sensing means are coupled to said steering means for sensing steering momentum and providing differential energizing of the power means for differentially driving said second pair of the wheels.
