A support cradle for a computer tomorgraph, in which the rotating body together with the X-ray emitter and the X-ray detector, which is situated opposite said emitter, can be ratably mounted. The support cradle includes a suitable pedestal that has two vertical supports, in addition to a gantry, which is mounted between the vertical supports and can be rotated about a horizontal transverse axis. According to the invention, the support cradle comprises a cooling device that is simple to manufacture. Said device is configured at least partially as a hollow section. A cavity in the support cradle acts as a conduit for supplying or evacuating a coolant.

The invention claimed is: 1. A support cradle for a computed tomography system, the support cradle comprising: a rotating body; a supporting ring for rotatably supporting the rotating body, the supporting ring having a hollow section with first and second hollow chambers fluidically separated from one another, the first hollow chamber forming an annular conduit for supplying a coolant to the rotating body, and the second hollow chamber forming an annular conduit for evacuating the coolant from the rotating body. 2. The support cradle as defined by claim 1, wherein the support cradle includes a pedestal, on which the supporting ring is supported rotatably about a horizontal transverse axis. 3. The support cradle as defined by claim 2, wherein a base plate of the pedestal has a hollow section. 4. The support cradle as defined by claim 3, wherein two transverse conduits extend in the transverse direction and are fluidically separated from one another in the base plate. 5. The support cradle as defined by claim 1 wherein the supporting ring has a substantially L-shaped profile, and wherein one of the annular conduits is in a first arm of the L-shaped profile, and the other of the annular conduits is in a second arm of the L-shaped profile. 6. The support cradle as defined by claim 1 wherein the supporting ring is supported with two aligned shaft segments secured to a circumference of the supporting ring, by a pedestal, and at least one shaft segment is a hollow section and communicates, for supplying or evacuating the coolant, with a corresponding annular conduit of the supporting ring. 7. The support cradle as defined by claim 1 wherein, along the course of each annular conduit, a number of openings are made in an inner wall of the supporting ring. 8. The support cradle as defined by claim 7, wherein a first annular conduit discharges axially with respect to the supporting ring onto an adjacent outer side of the rotating body, and wherein a second annular conduit discharges radially with respect to the supporting ring onto a wall of the rotating body. 9. The support cradle as defined by wherein the coolant is air. 10. The support cradle as defined by claim 4 wherein the supporting ring has a substantially L-shaped profile, and wherein one of the annular conduits is in a first arm of the L-shaped profile, and the other of the annular conduits is in a second arm of the L-shaped profile. 11. The support cradle as defined by claim 2 wherein the supporting ring is supported with two aligned shaft segments secured to a circumference of the supporting ring by the pedestal, and at least one shaft segment is a hollow section and communicates, for supplying or evacuating the coolant, with a corresponding annular conduit of the supporting ring. 12. A computed tomography system comprising: a blower and cooling unit; a supply line; an evacuation line for a cooling device that includes coolant; and a support cradle at least partly receiving the supply line and evacuation line and rotatably supporting a rotating body the support cradle having a hollow section with first and second hollow chambers fluidically separated from one another, the first hollow chamber forming an annular conduit for supplying the coolant to the rotating body, and the second hollow chamber forming an annular conduit for evacuating the coolant from the rotating body. 13. The computed tomography system as defined by claim 12, wherein the blower and cooling unit is disposed on a base plate and, for recirculating and cooling the coolant, is in fluidic communication with transverse conduits of the base plate. 14. The computed tomography system as defined by claim 12, wherein the first hollow chamber of the support cradle corresponds via first openings with a supply line of the rotating body; and wherein the second hollow chamber of the support cradle corresponds via second openings with an evacuation line of the rotating body.
