STATIC FIXED SUBSIDIARY DEVICE FOR MAGNETIC RESONANCE INSPECTION

摘要

PROBLEM TO BE SOLVED: To improve recognizability of marking in a subtraction image by connecting a chamber to a filling device through a conduit to fill the chamber with a first substance or a second substance exhibiting a different behavior in the respect of magnetic resonance technology. SOLUTION: An antenna for demarcating a space 9 for inspection has two conductor loops 10 and 12 crossing each other, which 10 and 12 receive a circularly magnetized resonance signal from the space 9 for examination. Pressure plates 14 and 16 are formed rectangular and chambers 22 manufactured as pipe are arranged therein 14 and 16 along the periphery thereof. The chamber 22 belongs to a marking device within a detection range of the antennas 10 and 12 and is filled with a liquid or gaseous substance convenient to replace and visually recognizable in an image of a cross section. The chambers 22 are interconnected through a tubular conduit 24 while being connected to a filling device 26, which 26 fills the chambers 22 with a first or second substance 28 or 30.
