Abstract

A safety device for an imaging medical apparatus comprising a patient entrance, in particular for a computer tomograph, a nuclear spin tomograph, a PET apparatus or a mobile x-ray apparatus such as for example a C-arc or a fluoroscope, wherein a proximity or contact detector is arranged in the area of the patient entrance. Furthermore, a braking device for a system comprising such an imaging medical apparatus and a patient carrier, which can be moved relative to each other, and to correspondingly equipped imaging medical apparatus.

Claims

1. An imaging medical apparatus equipped with a safety device, the imaging medical apparatus having a patient entrance and the safety device including a proximity or contact detector at the patient entrance.

2. The imaging medical apparatus as set forth in claim 1, wherein the imaging medical apparatus is a computer tomograph, a nuclear spin tomograph, a PET apparatus or a mobile x-ray apparatus.

3. The imaging medical apparatus as set firth in claim 2, wherein the mobile x-ray apparatus is a C-arc or a fluoroscope.

4. The imaging medical apparatus as set forth in claim 1, wherein the proximity or contact detector has a detection range in a plane of the patient entrance and/or at least partially protrudes out of said plane.

5. The imaging medical apparatus as set forth in claim 1, wherein the detector is arranged around the patient entrance.

6. A system comprising an imaging medical apparatus and a patient carrier, wherein the imaging medical apparatus and the patient carrier are capable of being moved relative to each other such that a patient can be moved into a patient entrance of the imaging medical apparatus, comprising;

a braking device, said braking device including a brake for inhibiting the relative movement between the imaging medical apparatus and the patient carrier; and

a proximity or contact detector operatively coupled to the brake, said detector being disposed at the patient entrance such that when an object comes within a specified proximity or contacts the detector, the detector provides a braking signal to the brake that inhibits the relative movement between the imaging medical apparatus and the patient carrier.

7. The system as set forth in claim 6, wherein the imaging medical apparatus is a computer tomograph, a nuclear spin tomograph, a PET apparatus or a mobile x-ray apparatus.

8. The system as set forth in claim 7, wherein the mobile x-ray apparatus is a C-arc or a fluoroscope.

9. The system as set forth in claim 6, wherein the system comprises a mobile medical apparatus and the brake operates to inhibit movement of the medical apparatus.

10. The system as set forth in claim 6, wherein the system comprises a mobile patient carrier, and the brake operates to inhibit movement of the carrier.

11. The system as set forth in claim 6, wherein the proximity or contact detector communicates to the brake via a wireless connection.

12. The system as set forth in claim 6, wherein the detector provides a signal to the brake that is proportional to a level of contact and/or a distance between the object and the detector.

13. A method for protecting against collision between a medical imaging device and a carrier for a patient, wherein the medical imaging device and carrier are relatively moveable, the method comprising outfitting the medical imaging device with a proximity or contact detector at an entrance of the medical imaging device, wherein the detector is operative to detect an imminent collision between the medical imaging device and the carrier and provides an output signal that causes relative movement between the imaging device and the carrier to be inhibited.
