A surgical table comprising a base and a patient support supported between opposed ends of the base, each opposed end including a pitch/roll assembly. The base is configured such that the patient support can be rolled and pitched relative to the opposed ends via the pitch/roll assemblies such that the roll axis of each pitch/roll assembly remains coaxial regardless of how the patient support is pitched or rolled relative to the base. The patient support includes an outer frame and an inner frame supported on, and displaceable relative to, the outer frame. The inner frame is further articulating about, and relative to, itself. The outer frame is rigid in that it does not change configurations.

1. A base for supporting a patient support structure of a surgical table, the base comprising: a first end support and a second end support opposing the first end support, each of the first and second end supports providing for vertical height adjustment above a floor;a first connection assembly including a first roll subassembly and a first pitch subassembly, the first connection assembly coupled between a first end of the patient support structure and the first end support, the first roll subassembly including a first roll axis about which the patient support structure is configured to roll;a second connection assembly including a second roll subassembly and a second pitch subassembly, the second connection assembly coupled between a second end of the patient support structure and the second end support, the second roll subassembly including a second roll axis about which the patient support structure is configured to roll, the second roll axis being substantially coaxially aligned with the first roll axis, the first and second pitch subassemblies allowing for angulation of the first and second roll axes of the first and second roll subassemblies upwardly or downwardly to maintain the coaxial alignment of the first and second roll axes when the first and second end supports change elevation relative to each other. 2. The base of claim 1, wherein each of the first and the second pitch subassemblies include at least one linear drive to actively maintain the coaxial alignment. 3. The base of claim 2, wherein the linear drive comprises a motor. 4. The base of claim 1, wherein the first and second roll axes are positioned above a longitudinal axis of the patient support structure. 5. The base of claim 1, wherein each of the first and second roll subassemblies comprises a worm drive driven by a motor. 6. The base of claim 1, further comprising a first end translation assembly coupling the first connection assembly and the first end support, the first end translation assembly configured to compensate for a change in effective distance between the first and second connection assemblies as the patient support structure transitions between different sloped orientations. 7. The base of claim 6, wherein the first end translation assembly is fixedly connected to a mount supporting the first connection assembly and facilitating displacement along a longitudinal axis of the base relative to the first end support, wherein the displacement via the first end translation assembly causes the first connection assembly to move relative to the first end support closer or further away from the second end support. 8. The base of claim 7, wherein the first end translation assembly is sandwiched between a top end of the first end support and the mount supporting the first connection assembly. 9. The base of claim 7, wherein the first pitch subassembly is pivotally connected to the mount. 10. The base of claim 7, wherein the first end support comprises a top end fixedly connected to a base plate of the first end translation assembly. 11. The base of claim 6, wherein the first end translation assembly comprises a servomotor. 12. The base of claim 1, further comprising: a first frame member coupled between the first connection assembly and the first end of the patient support structure; anda second frame member coupled between the second connection assembly and the second end of the patient support structure. 13. The base of claim 12, wherein the first and second frame members are maintained in substantially parallel alignment relative to each other via the first and second pitch assemblies. 14. The base of claim 12, wherein each of the first and second roll subassemblies comprises a respective ladder attachment assembly coupled to the respective first and second frame members. 15. The base of claim 14, wherein each ladder attachment assembly comprises upper and lower horizontal slots to retain a horizontal bar of the respective frame member, such that each frame member links the first and second ends of the patient support structure respectively to the respective ladder attachment assembly. 16. The base of claim 14, wherein the first and second frame members and the coupled ladder attachment assemblies are substantially parallel to each other. 17. The base of claim 1, wherein the first and second frame members are H-frames. 18. The base of claim 1, wherein the first end support remains a fixed distance from the second end support. 19. The base of claim 1, wherein each of the first and second end support comprises a telescopic arrangement. 20. The base of claim 19, wherein the telescopic arrangement comprises one of screw driven linear actuators, rack and pinion arrangements, or hydraulic or pneumatic rams. 21. A base for supporting a patient support structure of a surgical table, the base comprising: a first end support and a second end support opposing the first end support, each of the first and second end supports providing for vertical height adjustment above a floor;a first connection assembly including a first roll subassembly and a first pitch subassembly, the first connection assembly coupled between a first end of the patient support structure and the first end support, the first roll subassembly including a first roll axis about which the patient support structure is configured to roll; anda second connection assembly including a second roll subassembly and a second pitch subassembly, the second connection assembly coupled between a second end of the patient support structure and the second end support, the second roll subassembly including a second roll axis about which the patient support structure is configured to roll, the second roll axis being substantially coaxially aligned with the first roll axis, the first and second pitch subassemblies configured to angle the first and second roll axes of the first and second roll subassemblies upwardly or downwardly to maintain the coaxial alignment of the first and second roll axes when the first and second end supports change elevation relative to each other, wherein the first end support remains a fixed distance from the second end support. 22. A base for supporting a patient support structure of a surgical table, the base comprising: a first end support and a second end support opposing the first end support, each of the first and second end supports providing for vertical height adjustment above a floor;a first connection assembly including a first roll subassembly and a first pitch subassembly, the first connection assembly coupled between a first end of the patient support structure and the first end support, the first roll subassembly including a first roll axis about which the patient support structure is configured to roll; anda second connection assembly including a second roll subassembly and a second pitch subassembly, the second connection assembly coupled between a second end of the patient support structure and the second end support, the second roll subassembly including a second roll axis about which the patient support structure is configured to roll, the second roll axis being substantially coaxially aligned with the first roll axis, the first and second pitch subassemblies configured to angle the first and second roll axes of the first and second roll subassemblies upwardly or downwardly to maintain the coaxial alignment of the first and second roll axes when the first and second end supports change elevation relative to each other, the first and second roll axes positioned above a longitudinal axis of the patient support structure.
