New EIT Under Development

Electrical Impedance Tomography (EIT)

Maltron Sheffield MK 3.5

Welcome to the birth of a novel Imaging Technique in the Medical field that is non-invasive, and non-intrusive, with no radiation, and no side effects.

The Maltron Sheffield MK 3.5Electrical Impedence Tomography (EIT) device – is a state of art Impedance Imaging research and clinical tool that has applications in Pulmonary, Gastric and Body Segment monitoring, as well as Tissue characterisation.

Over 20 years of research and development in the field of Electrical Impedance Tomography has provided a state of art tool for a number of significant medical applications, as a safer and more cost effective method of assessing patients.

The Maltron Sheffield Mk 3.5 applies a set of electrodes around the area under investigation and then makes a series of impedance measurements. These measurements are then used to produce images.

Evolution of Electrical Impedance Tomography

Several designs have been implemented over 2 decades, giving Maltron Sheffield research team an unprecedented wealth of experience and knowledge that has led to continued product evolution.

Many of our designs have already been implemented, and the MK1 and SAPT systems have been especially popular for medical research groups the world over – making Maltron Sheffield the largest manufacturer of EIT systems in the world.

The latest MK3.5 was designed primarily for ease of applications and its use on neonates.

Over 2 decades of history of development which has resulted in the following products being implemented:

 

  • 16 Electrodes – 50KHZ data collection system
  • Miniature version of MK1, for use with astronauts and flown on the Russian MIR programme
  • 16 Electrodes – 20KHZ.
  • 16 Electrodes – Operating at 8 frequencies from 9.6KHZ TO 1.2MHZ
  • 64 Electrodes – Operating from 9.6KHZ TO 1.2MHZ
  • 8 Electrodes – 2KHZ to 1.6MHZ at 30 frequencies.

Advantages of MK 3.5 Electrical Impedence Tomography

Bone is a poor conductor, whereas muscle is a relatively good conductor.

Biological tissues conduct electricity as they contain ions, which act as charge carriers. Some tissues conduct electricity better than others because they contain more ions that are free to carry charge.

The MK 3.5 offers several advantages over other body imagining and monitoring methods:

  • Low Cost
  • No known hazards
  • Long term monitoring of Physiological function is possible
  • Rapid data collection so that changes in function can be measured
  • Can use spectral measurements to make tissue characterisations
