Digital radiography imaging system with rotatable display and controls
View Patent ↗A digital radiography system for imaging a subject. A support structure, coupled to an X-ray source and an X-ray imaging detector, is rotatable about a first axis and is linearly moveable. The X-ray source and the X-ray imaging detector are also rotatable about second and third axes, respectively, to provide an operator with a number of degrees of freedom to move the X-ray source and the X-ray imaging detector to different positions relative to a subject. Further, the system has means for coupling an operator control interface and a display to the X-ray source for permitting an operator to rotate them about a fourth axis so that the operator control interface and display are accessible to the operator such that the position of the operator does not have to change when the positions of the X-ray source and the X-ray detector are changed.
1. An apparatus comprising:
a radiography system including: an X-ray source, an X-ray imaging detector, and a rotatable support structure coupling the X-ray source and the X-ray detector, the support structure being rotatable about a first axis to position the X-ray source and the X-ray imaging detector at various rotational positions about a subject; and
an operator control interface mounted on the rotatable support structure for rotation about a second axis that is substantially parallel to the first axis such that the operator control interface can rotate around the substantially parallel axis so that the orientation between the operator control interface and the operator remains constant when the support structure rotates about the predetermined axis.
2. The apparatus as set forth in claim 1 , wherein the first axis substantially horizontal when the radiography system is in use.
3. The apparatus as set forth in claim 1 , wherein the operator control interface includes a first display having a scene orientation with a top and a bottom, the scene orientation remaining constant when the support structure rotates about the first axis.
4. The apparatus of claim 3 , wherein the operator control interface includes a second display having a scene orientation with a top and a bottom, the scene orientation of the second display remaining constant when the support structure rotates about the first axis.
5. A digital radiography system with an operator control interface, comprising:
an X-ray source;
an X-ray imaging detector;
a support structure coupled to the X-ray source and the X-ray detector and rotatable about a first axis and linearly moveable, the X-ray source and the X-ray imaging detector being rotatable relative to the support structure about second and third axes, respectively, to thereby provide an operator with a number of degrees of freedom of motion of the X-ray source and the X-ray imaging detector to move them to different positions relative to a subject; and
an operator control interface attached to the support structure whereby the operator can position the X-ray source relative to the X-ray imaging detector, the operator control being coupled to the X-ray source such that the operator can to rotate the operator control interface about a fourth axis.
6. The digital radiography system of claim 5 , adapted for linear movement of the X-ray source and the X-ray imaging detector relative to each other to change the distance between the X-ray source and the X-ray imaging detector.
7. The digital radiographic system of claim 5 , wherein the operator control interface includes a first display.
8. The digital radiographic system of claim 5 , further comprising a second display is affixed to the support structure.
9. The digital radiography system of claim 5 , further comprising:
a telescoping support member coupled to the support structure;
a moveable base coupled to the telescoping support member opposite the support structure, wherein the moveable base is moveable along a predetermined path; and
a coupler connected to the support structure and the telescoping support member that permits rotation of the support structure about a fifth axis.
