## Abstract

A C-arm for a medical examination device or therapeutic device, is designed as a cast metal component. In at least one embodiment, one or more reinforcement profile, extending at least in certain sections along the C-arm, are cast in.

## Claims

### Claim 1

A C-arm for a medical examination device or therapeutic device, designed as a cast metal component, the C-arm including one or more reinforcement profiles, extending along the C-arm at least in certain sections, cast in.

### Claim 2 (depends on 1)

The C-arm of claim 1, wherein the one or more reinforcement profiles is a hollow profile.

### Claim 3 (depends on 2)

The C-arm of claim 2, wherein the cast metal component is made of aluminum and the one or more reinforcement profiles is made of steel.

### Claim 4 (depends on 2)

The C-arm of claim 2, wherein the C-arm includes a rectangular hollow cross-section, and wherein the one or more reinforcement profiles includes four reinforcement profiles, arranged in a rectangular shape.

### Claim 5 (depends on 4)

The C-arm of claim 4, wherein two adjacent reinforcement profiles are connected together by one or more connecting elements.

### Claim 6 (depends on 5)

The C-arm of claim 5, wherein the one or more connecting elements is a sheet or a panel.

### Claim 7 (depends on 6)

The C-arm of claim 6, wherein the sheet or panel includes through holes.

### Claim 8 (depends on 1)

The C-arm of claim 1, wherein the cast metal component is made of aluminum and the one or more reinforcement profiles is made of steel.

### Claim 9 (depends on 1)

The C-arm of claim 1, wherein the C-arm includes a rectangular hollow cross-section, and wherein the one or more reinforcement profiles includes four reinforcement profiles, arranged in a rectangular shape.

### Claim 10 (depends on 9)

The C-arm of claim 9, wherein two adjacent reinforcement profiles are connected together by one or more connecting elements.

### Claim 11 (depends on 10)

The C-arm of claim 10, wherein the one or more connecting elements is a sheet or a panel.

### Claim 12 (depends on 11)

The C-arm of claim 11, wherein the sheet or panel includes through holes.

### Claim 13 (depends on 1)

A medical examination device comprising the C-arm of claim 1.

### Claim 14 (depends on 1)

A therapeutic device comprising the C-arm of claim 1.

### Claim 15

A method for producing a C-arm for a medical examination device or therapeutic device, the method comprising:
introducing one or more reinforcement profiles, extending along the C-arm at least in certain sections, into a casting mold; and
casting the C-arm by embedding the one or more reinforcement profiles in the casting mold.

### Claim 16 (depends on 15)

The method of claim 15, wherein one or more hollow profiles is used as the one or more reinforcement profiles.

### Claim 17 (depends on 16)

The method of claim 16, wherein the C-arm is cast from aluminum and wherein the one or more reinforcement profiles is made of steel.

### Claim 18 (depends on 15)

The method of claim 15, wherein the C-arm is cast from aluminum and wherein the one or more reinforcement profiles is made of steel.

### Claim 19 (depends on 15)

The method of claim 15, wherein the one or more reinforcement profiles are arranged in a rectangular shape and are cast in a region of corners of the C-arm, including a rectangular hollow cross-section.

### Claim 20 (depends on 15)

The method of claim 15, wherein the one or more reinforcement profiles include two adjacent reinforcement profiles, connected together by one of more connecting elements, the one or more connecting elements being cast in.

### Claim 21 (depends on 20)

The method of claim 20, wherein one or more sheets or one or more panels are used as the one or more connecting elements.

### Claim 22 (depends on 21)

The method of claim 21, wherein the one or more sheets or one or more panels include through holes.
