1. A lifting subassembly for a patient positioning apparatus having a base and a patient support structure, comprising: a) a lifting subassembly reversibly attachable to the base and having first and second lifting positions with respect to the base, wherein:b) the lifting subassembly is adapted to move the patient support structure from the first lifting position to the second lifting position in a vertical direction above a floor; andc) the lifting subassembly is reversibly rotatably from the first lifting position to the second lifting position with respect to the base. 2. The lifting subassembly according to claim 1, wherein the lifting subassembly is removable when in the second lifting position. 3. The lifting subassembly according to claim 1, wherein the lifting subassembly comprises: a) a pair of spaced parallel elongate support members, each elongate support member having first and second ends;b) spaced parallel first and second brace members, the first brace member joining the first ends of the elongate support members and the second brace member joining the second ends of the elongate support members, so as to provide a frame structure; andc) a carrier member located between the brace members and reversibly movable along a length of the elongate support members, whereby the patient support structure is slidingly moved between the first and second lifting positions. 4. The lifting subassembly according to claim 3, further comprising a lifting mechanism adapted to move the carrier member. 5. The lifting subassembly according to claim 4, wherein the lifting mechanisms includes: a) a lead screw spaced from and parallel with the support members and joined with the brace members; andb) a gear subassembly engaging the lead screw so as to move the carrier member along the length of the support members. 6. The lifting subassembly according to claim 3, wherein the carrier member includes at least one engagement member adapted for reversibly engaging the patient support structure. 7. The lifting subassembly according to claim 3, wherein the carrier member includes a pair of spaced parallel ring members, each ring member including a through-bore slidingly receiving one of the elongate support members therethrough, whereby the carrier member is movable between the brace members. 8. The lifting subassembly according to claim 3, wherein at least one of the brace members includes a connection portion adapted for reversible engagement of the base structure. 9. The lifting subassembly according to claim 1, wherein the lifting subassembly comprises a pair of lifting subassemblies. 10. The lifting subassembly according to claim 1, further comprising an actuator. 11. A patient positioning apparatus for positioning a patient on a patient support structure for a medical procedure, the patient support structure having a base supporting a removably attachable patient support frame above a floor and a rotation mechanism for rotating the patient support frame about a longitudinally extending roll axis and between first and second lifting positions with respect to the floor, the patient positioning apparatus comprising: a) a lifting subassembly reversibly attachable to the base and having a connection portion slidingly movable between the first and second lifting positions with respect to a length of the lifting subassembly; andb) a transfer table sized and shaped for receiving and supporting a patient thereon and reversibly attachable to the lifting subassembly. 12. The apparatus according to claim 11, further comprising an actuator for actuating the lifting subassembly, so as to move the transfer table between the first and second lifting positions. 13. The apparatus according to claim 11, wherein the transfer table includes a bracket for reversible attachment to the lifting subassembly. 14. The apparatus according to claim 11, wherein the transfer table includes radio-transparent tabletop member. 15. The apparatus according to claim 11, wherein the lifting subassembly includes first and second lifting subassemblies. 16. The apparatus according to claim 15, wherein the first and second lifting subassemblies are independently movable. 17. The apparatus according to claim 15, each of the lift subassemblies comprising: a) a pair of spaced apart and substantially parallel support members;b) a lead screw spaced from and substantially parallel with the support members;c) a first brace member joining a first end of each of the support members and the lead screw, the first brace member including an attachment structure for removable attachment to a respective vertical support subassembly;d) a second brace member joining a second end of each of the support members and the jack screw; ande) a carrier member slidably engaging the support members, the carrier member having i) a gear subassembly operably engaging the lead screw so as to reversibly move the carrier member toward the first brace member, andii) a bracket for releasable hingeable attachment to the transfer table. 18. The apparatus according to claim 17, the gear subassembly comprising: a) a lead nut rotatably engaging the lead screw; andb) a motor connector for operable engagement of an external motor. 19. The apparatus according to claim 17, the carrier member including: a) a pair of sliding brackets, each sliding bracket being sized and shaped to slidably engage a support member. 20. The apparatus according to claim 15, further comprising an actuator adapted to synchronously actuate the first and second lifting subassemblies, so as to maintain the transfer table in a plane substantially parallel to the roll axis while moving the transfer table between the first and second lifting positions. 21. The apparatus according to claim 20, wherein one of the first and second lifting positions is closer to the patient support structure than the other of the first and second lifting positions. 22. The apparatus according to claim 21, wherein when in the closer of the first and second lifting positions, a patient on the transfer table is substantially sandwiched between the transfer table and the patient support structure. 23. A method of transferring a patient to a medical patient support structure in a prone position, the patient support structure including a base with spaced head-end and foot-end vertical support subassemblies, a patient support frame removably attached to and supported by the vertical support subassemblies, and a rotation mechanism for rotating the patient support frame about a longitudinally extending roll axis a distance of up to at least about ±180°, the method comprising: a) providing a patient positioning apparatus having head-end and foot-end lift subassemblies and a transfer table;b) releasably attaching the patient positioning apparatus to the patient support structure;c) orienting the patient positioning apparatus for patient transfer;d) placing a patient on the transfer table in a supine position;e) actuating the head-end and foot-end lift subassemblies so as to move the patient toward the patient support frame, such that the patient is snugly sandwiched between the transfer table and the patient support frame;f) rotating the patient support structure to a first position, such that the patient supported by the patient support frame in a prone position; andg) detaching the patient positioning apparatus from the patient support structure. 24. The method according to claim 23, wherein releasably attaching the patient positioning apparatus to the patient support structure comprises: a) attaching the head-end lift subassembly to the head-end vertical support subassembly;b) attaching the foot-end lift subassembly to both the foot-end vertical support subassembly; andc) attaching the transfer table to the head end and foot-end lift subassemblies. 25. The method according to claim 23, wherein orienting the patient positioning apparatus for patient transfer comprises rotating the patient support structure from the first position about ±180° about the roll axis such that the transfer table is located below the patient support frame. 26. The method according to claim 23, wherein actuating the head-end and foot-end lift subassemblies comprises actuating a gear subassembly so as to rotate a lead nut relative to a lead screw.
