CLAIMS

1. A system for medical examination of a patient under variable and controllable conditions which include inducement of gravitational effects, said system comprising:
chair means for supporting a seated patient,
said chair means being generally vertically oriented, selectively adjustable and movable relative to the vertical so as to
selectively and controllably stress the
patient and said chair means being
generally stationary during examination;
examination means including an annularly-shaped examination device oriented in a generally horizontal attitude and having a central
opening, said examination means for use in the internal examination of a patient
under stress conditions;
support means for supporting said examination
means in said generally horizontal attitude and for moving said device upwardly
and downwardly relative to the vertical
and in surrounding relationship to said
chair means in said examining position;
and
said chair means being positioned within said
support means and relative to said examination means so that said examination
means may be moved downwardly around said
chair means so as to surround the same for examination of the patient, whereby images of said patient in a generally vertical
and stressed condition can be obtained.

2. An examination device as in claim 1, wherein the examination device is of a radiation-type wherein radiation is emitted from one side of the device, across the central opening, through a patient to be examined, received on the other side and an image is formed.
3. A device as in claim 1, wherein said chair means is selectively tiltable in the forward or rearward direction.
4. A device as in claim 1, wherein said chair means includes seat means for supporting a patient and generally upright back means pivotally connected to said seat means and selectively and controllably pivotable relative to said seat so as to control the flexion and attitude of a patient.
5. A device as in claim 1, wherein said chair means includes pivot means for pivoting said chair means about a vertical axis.
6. A device as in claim 1, wherein said chair means includes vertical movement means for moving said chair means vertically.
7. A device as in claim 6, wherein said vertical movement means is constructed to move said chair means vertically and incrementally.
8. A device as in claim 3, wherein said examination means and support means are constructed to cooperate, whereby said examination means is angularly displaceable relative to a horizontal plane and about a horizontal axis substantially transverse to the for-ward and rearward tilting direction of the chair means.

9. A device as in claim 1, wherein said support means includes a frame having at least three support means.
10. A device as in claim 9, wherein said frame is rectangularly shaped and there are four support means, one at each corner of the frame.
11. A device as in claim 1, wherein patient restraint means for minimizing patient movement are provided.
12. A method for examining a patient for a spinal dysfunction using an annularly-shaped non-invasive examination device and patient positioning means for selectively positioning and controllably stressing a patient so as to examine a patient in a generally vertical position and under different stress conditions, including gravitational effects:
seating a patient in positioning means for
selectively orienting the patient in a
generally vertical and substantially
stationary position where the effect of
gravity is optimized;
moving the non-invasive examination device
about a patient in a substantially
horizontal plane;
orienting the non-invasive examination device
about a patient to optimize examination of a patient's spine; and
operating the non-invasive examination device
so as to image a patient's spine.
13. A method as in claim 12, including the step of tilting the patient in a forward or a rearward direction.
14. A method as in claim 12, wherein said method includes the further steps of applying a load to said patient so as to additionally stress the patient's back.
15. A method as in claim 14, wherein said patient is seated in a chair having a seat and pivotable back secured thereto and said additional stress is applied by controllably moving said back so as to controllably flex the patient's back.
16. A method as in claim 12, wherein said examination device is angularly displaced about a substantially horizontal axis that is generally
transverse to the direction of tilting of the patient's chair.
17. A method as in claim 12, wherein said patient's chair is vertically movable for permitting examination of selected areas.
18. A method as in claim 17, wherein said chair is movable vertically in increments.
19. A method as in claim 12, wherein said examination device is angularly displaceable about a horizontal axis generally transverse to said chair tilting direction and said method includes the step of tilting said device about said axis so as to enhance an image of the patient.
