Scanners

Imaging investigation techniques have already been used in medical technology for decades. Development is moving towards techniques which produce increasingly detailed spatial images; in other words, which enable better test results, whilst simultaneously protecting the patients. To do this, the X-ray pipes and the detector rotate at high speed around the patient.

Our bearings used here are designed so that they work smoothly and precisely, even at high speeds. In this way, thyssenkrupp rothe erde makes an important contribution to medical progress.

Luggage scanners, which are used for security checks at airports, among other uses, constitute a further application with similar requirements.

Different types of scanners are used in medical technology. The most well-known methods are the computer tomograph (CT) and the magnetic resonance tomograph (MRT). With these devices, the pipes and detector rotate around the patients. This allows sectional images to be produced from which the doctor can obtain valuable physiological information for his diagnosis.

So that patients who are exposed to the equipment during the test feel relaxed, a quiet operation and high running precision are particularly important. The same applies to ensuring the frictional torque processes are uniform, even at high speeds.

Checking luggage plays an important role in flight security and in the security of public spaces. A large proportion of rucksacks, suitcases and bags have to be checked for unsafe objects within a short period of time. All this must be achieved without downtime and with a one hundred percent hit rate. For this, scanners which rotate at a high speed are used. In addition, the machines have to be very quiet wherever there are people in the immediate vicinity, for example at the security gate in the airport. This means bearings made by thyssenkrupp rothe erde are an important component in the construction of high-quality luggage scanners.
