Arrangement for measuring physiologically generated weak biomagnetic signals while the examination subject is at rest and exercising

摘要

A multi-channel arrangement for measuring weak magnetic fields in living tissues, and for localizing the current sources which cause the magnetic fields by evaluating the topical magnetic values measured by individual sensors of the apparatus mounted in a vertically adjustable fashion to a patient support, the patient support being longitudinally and transversely adjustable, has a bicycle ergometer disposed at a foot end of the patient support, the bicycle ergometer consisting exclusively of components which are nonmagnetic and which do not generate a magnetic field. The bicycle ergometer is used by an examination subject so that signals can be obtained by the subject at rest and at a defined exertion level. The bicycle ergometer is mounted and constructed so that the examination subject can operate the ergometer after being positioned in a fixed position on the support.
