New technology makes 3-D imaging quicker, easier

19.02.2008
Possible applications of technology widespread

Technology invented by scientists from The Johns Hopkins University and Ben-Gurion University of the Negev can make three-dimensional imaging quicker, easier, less expensive and more accurate, the researchers said.

This new technology, dubbed FINCH, for Fresnel incoherent correlation holography, could have implications in medical applications such as endoscopy, ophthalmology, CT scanning, X-ray imaging and ultrasounds, co-inventor Gary Brooker said. It may also be applicable to homeland security screening, 3-D photography and 3-D video, he said.

A report presenting the first demonstration of this technology -- with a 3-D microscope called a FINCHSCOPE -- will appear in the March issue of Nature Photonics and will be available on the Nature Photonics Web site on Feb. 17.

“Normally, 3-D imaging requires taking multiple images on multiple planes and then reconstructing the images,” said Brooker, director of the Johns Hopkins University Microscopy Center on the university’s Montgomery County Campus.

“This is a slow process that is restricted to microscope objectives that have less than optimal resolving power,” said Brooker, a research professor of chemistry in Krieger School of Arts and Sciences who also has an appointment in the Whiting School of Engineering Advanced Technology Laboratory. "For this reason, holography currently is not widely applied to the field of 3-D fluorescence microscopic imaging.”

The FINCH technology and the FINCHSCOPE uses microscope objectives with the highest resolving power, a spatial light modulator, a charge-coupled device camera and some simple filters to enable the acquisition of 3-D microscopic images without the need for scanning multiple planes.

The Nature Photonics article reports on a use of the FINCHSCOPE to take a 3-D still image, but moving 3-D images are coming, said Brooker and co-inventor Joseph Rosen, professor of electrical and computer engineering at Ben-Gurion University of the Negev in Israel.

“With traditional 3-D imaging, you cannot capture a moving object,” Brooker said. “With the FINCHSCOPE, you can photograph multiple planes at once, enabling you to capture a 3-D image of a moving object. Researchers now will be able to track biological events happening quickly in cells.”

"In addition, the FINCH technique shows great promise in rapidly recording 3-D information in any scene, independent of illumination,” Rosen said.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
