Due to increasing life expectancy, growing health awareness and technical innovations, medical technology is one of Germany's key technologies. As an application of engineering sciences in the field of medicine, it has become indispensable in many medical areas: For example, it plays a role in diagnosis in the derivation of biosignals (e.g. ECG), in imaging procedures (e.g. X-ray or ultrasound examinations) and in the determination of lung parameters or blood tests. It is also used in therapy, for example in pacemakers, artificial kidneys and ventilators. In the digital age, both the processing of patient data and signal analysis and image processing using various software are essential. Medical technicians are involved in the development, operation and maintenance of a wide variety of devices and systems.
