Shows:
          Soft materials: plastic and cartilage (totally new ability)
          Dense materials: metal and bone (like normal radiography)

Advantages

  • See features invisible in normal x-ray images
  • Better resolution (higher contrast)
  • Non-destructive composition analysis
  • Reduce x-ray exposure by at least 90%
  • Simultaneous soft & dense tissue analysis

All the images presented on our website have been collected on a DEXI-LRM1 instrument. The current machine's technical characteristics can be modified to suit customer's needs with customer-specified options, e.g., a specimen stage with either 1- or 2-dimensional translation and 1- or 2-axis rotational capabilities, etc. The instrument is currently designed to use monochromatic Ag Ka1 radiation (22KeV).

Instrument Description

The current instrument has been operational since June, 2007. Commercial instruments will have numerous improvements, such as a specimen stage with either 1- or 2-dimensional translation  and 1- or 2-axis rotational capabilities as customer-specified options, in addition to integrated hardware interlocks and safety enclosure. The instrument is currently setup to use monochromatic Ag Kα1  radiation. We are also investigating the possibility to incorporate higher energy, 35 keV radiation.

How It Works

CONVENTIONAL TECHNOLOGY

Imaging information is based solely on differences in absorption of x-rays by different parts of the specimen. Therefore, you see bones in soft tissue (bones absorb more than the soft tissue) and metal reinforcement within plastic parts (metal absorbs more than plastic). But lighter materials themselves like muscle, ligaments, carbon fiber and plastic hardly absorb x-rays at all, thus they cannot be seen or identified.

 



OUR TECHNOLOGY

Utilizing patented Diffraction Enhanced Imaging technology, our x-ray imaging machine measures very tiny deflections in a highly parallel x-ray beam as it goes through materials of different densities, such as a tumor within healthy tissue or a crack in a plastic part. These tiny deflections are exquisitely sensitive to a specimen's composition, homogeneity, and integrity. Therefore, the machine offers exciting applications in the areas of materials characterization, security, scientific research and medicine.

Nesch, LLC is vigorously pursuing these applications and is eager to discuss your interests and needs with you at your earliest convenience.
