Electrode belt
First Claim
1. An electrode belt for electrical impedance tomography, the electrode belt comprising:
- a belt material;
16 or more electrodes connected to said belt material, said belt material being elastic in some sections such that said belt material can be stretched from a non-stretched state to a stretched state, the electrode belt fully surrounding a test subject to be examined over the circumference of the body;
electrode feed lines extending within one or more hollow elastic tubes, each electrode feed line having a defined length, said electrode feed lines being integrated within said belt material such that the entire length of each electrode feed line extends within said belt material, each electrode feed line having a length between electrodes that is greater than the length of said tubes between electrodes when the belt material is in a non-stretched state; and
a feed line, said electrode feed line being connected to said feed line at one or more feed points along said belt material.

Abstract
An electrode belt for impedance tomography shall be improved such that it has a simple design and makes possible good contacting of the electrodes (2) with the body of the test subject to be examined. The electrode belt (1) has at least 16 electrodes (2) on an electrode holder or belt material (3), which is elastic at least in some sections. The belt formed of one or more belt material sections completely surrounds a test subject to be examined on the circumference of the body. Electrode feed lines (63) extend along the electrode holder (3). The electrode feed lines and are connected to a feed line (6) at least at one feed point (4) on the electrode holder (3).
