PCT No. PCT/CH92/00194 Sec. 371 Date May 24, 1993 Sec. 102(e) Date May 24, 1993 PCT Filed Apr. 1, 1993 PCT Pub. No. WO93/05700 PCT Pub. Date Apr. 1, 1993A process for measuring parameters of organs and tissues, especially blood flow through an organ, particularly the liver, is based on a medical technology apparatus that can be constructed in modular fashion. The preferred process uses the hydrogen clearance method to determine blood flow. The preferred apparatus includes at least one measuring instrument and at least one measuring or therapy sensor that is detachable from that instrument. Additional connecting elements make it possible to construct an individually adapted measurement array. For a monitoring and checking operation, both the sensors or therapy heads, and the various connecting elements are equipped with electronic code elements which can be systematically read and evaluated by at least one of the measuring instruments used.
