Abstract
Abstract The invention at hand concerns a device for supporting the patient in panoramic X-ray radiography. The device has a certain head supporting equipment to support the patient's head in order to keep it in a fixed position during the X-ray radiography. The device also has equipment for placing the patient's head in the right position for radiography. These make it possible to move the X-ray machine in relation to the head supporting equipment, so that the patient's head can be placed in the appropriate position in relation to the X-ray machine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A device for supporting a patient during panoramic X-ray radiography comprising: (a) support structure; (b) a radiation source; (c) a film holder, said radiation source and said film holder being mounted on said supporting structure on opposite sides of a patient to be radiographed when situated therebetween; (d) a base having a pair of vertically spaced, horizontally extending arms; (e) means fixedly secured to the upper arm of said base for supporting the upper portion of the head of a patient; (f) means movably suspending said supporting structure from the upper arm of said base for rotational and horizontal linear movement relative to said base and the upper arm; (g) indicator means supported on the lower arm of said base and adapted for horizontal linear movement relative to the lower arm and said base and the patient for indicating the position of the layer to be radiographed in relation to the patient; and (h) means coupling said indicator means and said movable suspension means for horizontally, linearly moving said movable suspension means in unison with said indicator means.
Claim 2
Independent Claim
178 words
A device for supporting a patient during panoramic X-ray radiography comprising: (a) support structure; (b) a radiation source; (c) a film holder, said radiation source and said film holder being mounted on said supporting structure on opposite sides of a patient to be radiographed when situated therebetween; (d) a base having a pair of vertically spaced, horizontally extending arms; (e) means fixedly secured to the upper arm of said base for supporting the upper portion of the head of a patient; (f) means movably suspending said supporting structure from the upper arm of said base for rotational and horizontal linear movement relative to said base and the upper arm; (g) indicator means supported on the lower arm of said base and adapted for horizontal linear movement relative to the lower arm and said base and the patient for indicating the position of the layer to be radiographed in relation to the patient; and (h) means coupling said indicator means and said movable suspension means for horizontally, linearly moving said movable suspension means in unison with said indicator means.
Claim 3
Dependent Claim
45 words
The device of claim 1 including a slide member movably supported on the lower arm of said base member for linear movement with said suspension means and supporting said indicator means for indicating the linearly moved position of said suspension means relative to the patient.
Claim 4
Dependent Claim
28 words
The device of claim 1 or 2 wherein said suspension means moves linearly in the direction of the axis of symmetry of the dental arch of a patient.
