چکیده
Abstract: EIT can image the distribution of ventilated lung tissue, and is thus a promising technology to help monitor patient breathing to help selection of mechanical ventilation parameters. Two key di culties in EIT instrumentation make such monitoring di cult: 1) EIT data quality depends on good electrode contact and is sensitive to changes in contact quality, and 2) EIT electrodes are di cult and time consuming to place on patients. This paper presents the design and initial tests of an active electrode based system to address these di culties. An electrode belt is designed incorporating 32 active electrodes, each of which contains the electronic ampli ers, switches and associated logic. Tests show stable device performance with a conventient ease of use and good imaging ability in volunteer tests.

Two key difficulties in EIT instrumentation make such monitoring difficult: (1) EIT data quality depends on good electrode contact and is sensitive to changes in contact quality, a...
متن کاملFast EIT data acquisition system with active electrodes and its application to cardiac imaging.
A wide-band high-speed data acquisition system for electrical impedance tomography (EIT) is described. 32 active electrodes are used in the system, half of them as receive electrodes and the other half as drive electrodes. A buffer is mounted on the back of each receive electrode and a current source on each drive electrode. A multielectrode system with active electrodes was built to make it co...

Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...
متن کاملDirect calculation of the electrode movement Jacobian for 3D EIT
Electrical Impedance Tomography (EIT) of media with deformable boundaries is very sensitive to electrode movement. This is especially important for EIT images of the thorax, which become distorted with breathing and posture change. Previously, we proposed a reconstruction method for imaging conductivity change and electrode movement based on an indirect perturbation Jacobian calculation, involv...
