Biomedical diagnostics using personalized 3D imaging

Researchers at the firm 4DNature and the Universidad Carlos III of Madrid (UC3M) are developing a technology – helical optical projection tomography – that improves biomedical diagnostic 3D imaging. Helical optical projection tomography consists in rotating a sample while moving it vertically in order to obtain a three-dimensional image of it.

“With our design and the software we are developing, we can create equipment that is not available commercially and that has the advantage of evolving at the same time as the project it is being used for progresses,” explains Jorge Ripoll, a partner in 4D-Nature and professor in UC3M’s Bioengineering Department.

This type of technology is essential in the development of new medicines, sensors, and other types of biomedical research applicable to clinical diagnostic imaging.

Dimensional and application information for designers

Engineers and OEM designers incorporate miniature and thin-section bearings into surgical and diagnostic imaging devices, precision pumps, and measurement equipment, and the Timken Miniature and Thin-Section Bearings Catalog, is a resource guide for these applications. Timken is a manufacturer of precision bearings and assemblies in miniature and thin-section series using high quality steel and components manufactured to extremely tight tolerances, keeping the most demanding application challenges in mind. Standard sizes range from 0.025" to 11" bore (1mm to 280mm).

Sections in the new catalog include:

  • Engineering
  • Miniature and instrument ball bearing product tables
  • Thin-section ball bearing product tables

The catalog is available in printed and electronic formats.


Top 10 technology to watch

ECRI Institute, a U.S. based non-profit health organization has named antimicrobial copper as one of its top 10 technologies to watch. This comes following a study showing how copper kills bacteria and reduces infections. The 2014 Top 10 Hospital C-Suite Watch List serves as a reference guide on upcoming noteworthy health technologies.

While copper’s antimicrobial properties are known, recent research piloted by the Copper Development Association (CDA) and funded by the Department of Defense (DOD) proved that surfaces made from antimicrobial copper alloys like brass and bronze had 83% fewer bacteria on average compared to surfaces made from traditional materials.

The list notes, “Antimicrobial copper is the only hospital touch surface with a U.S. Environmental Protection Agency (EPA) public health registration, allowing manufacturers to claim that copper surfaces can kill specific bacteria…that cause infections and pose a threat to human health.”


Engineer-to-engineer community

Festo Support Community is a global users’ forum where community members can post questions 24/7, or answer already posted questions. Forum topics include pneumatics, servo pneumatics, electric drives, software, fieldbus, process automation, sensors and vision, directives, and standards. Among the convenience features, members are alerted when replies are posted to their questions, they can sign up for RSS or Atom feeds, and they can email and print topics.

Animation and films, along with written replies, are available on some posts. Additional online options for registered members include downloading of native CAD models and the ability to save, import, and export parts lists. Visit the Support Community to learn more.
