Problems solved by technology

[0003] A basic problem in all X-ray devices is that 99% of the electrical energy used in the generation of X-rays by the X-ray source is converted into heat energy
[0005] In the cooling system mentioned, it has proven to be disadvantageous in the need for a number of precise mechanical and electrical components, which, in view of their function, are subject to wear and must be repaired accordingly
Another disadvantage is that due to the required dimensions of the heat exchanger, the rack housing must have a correspondingly large volume
But its disadvantage is that the cooling of the cooling medium is only possible if there is sufficient rest time
Usually, the required coupling with an external cooling medium circulation makes it difficult to mount the carriage housing pivotably on a fixed part of the computed tomography apparatus.

Embodiment Construction

[0033] The computed tomography apparatus 1 shown in FIG. 1 has a stationary part 2 (hereinafter also referred to as carriage base 2 ) and a carriage housing 3 mounted movably thereon as essential components. The housing 3 is mounted pivotably about an axis A by means of two coaxial bearings 9 , 10 on opposite sides of the fastening part 2 of the computed tomography apparatus 1 . Located in the housing 3 is a rotatably mounted barrel 4 in the direction of rotation R, on which an x-ray source 5 and a detector 6 are arranged opposite each other. When the computed tomography apparatus 1 is in operation, the barrel frame 4 rotates around an object to be inspected (a patient P in the figure) lying on a bed 29 in the inspection chamber 8, one of which is emitted by the X-ray source 5 The emitted fan-shaped X-ray beam penetrates through the object P to be inspected and is projected onto the detector 6 . Thus, a tomographic image of a layer within the rotation plane within the object ...

Abstract

A cooling system is provided for components of a computer tomography system that are arranged in a gantry housing. The cooling system includes a cooled air feed device with an air compressor and connected streaming elements that are arranged and / or fashioned such that compressed air flows onto the components to be cooled. Moreover, a corresponding method is provided for cooling the components of a computer tomography system arranged in a gantry housing.

Description

technical field [0001] The invention relates to a cooling system for cooling components of a computed tomography apparatus arranged in a gantry housing. Furthermore, the invention relates to a corresponding cooling method for cooling these components. Background technique [0002] In computed tomography systems, a three-dimensional tomogram of the interior of an object to be examined is generated by means of an x-ray method. For this purpose, two-dimensional x-ray tomograms are generated by means of a scanning unit (often referred to as a barrel frame) which usually has an x-ray source that can be rotated around the subject and an image recording system, from which a three-dimensional tomogram is reconstructed photo. In this case, the barrel holder is usually located in a barrel holder housing which is arranged in a ring around a recording chamber of the object to be examined. [0003] A fundamental problem in all X-ray devices is that 99% of the electrical energy used in...
