Ergometer suitable for use with magnetic resonance devices

摘要

The ergometer has a test device e.g. pedal, arranged at a piston (20) or a cylinder (21). A pneumatic pressurization between the piston and the cylinder represent a resistance and/or force for the operation of the device through the test persons. The resistance and the force for movement of the test device are manually controlled by trained personnel and automatically controlled by computer program during the test device operation. An air buffer is formed between the piston and the cylinder in a pneumatic piston-cylinder arrangement (7). Independent claims are also included for the following: (1) an ergometer assembly (2) a method of operating an ergometer (3) an application of an ergometer, an ergometer assembly and/or a method of operating an ergometer.
