PNNL researchers paired multiple QCLs with the tuning forks, allowing simultaneous examination of a single sample at many infrared wavelengths. Nearly every molecule has unique optical properties at infrared wavelengths b...

Computer imaging assists with facial reconstructive surgery

...amento performed a photograph analysis and medical record review of 14 patients (average age 32, 12 females and two males) who underwent combined rhinoplasty (nose surgery) and chin correction at an academic medical center between 1999 and 2004.

Bioluminescence at the service of a novel cerebral imaging technique

...ng this imaging technique, it has been possible to record neurons in the ellipsoid body, a structure involved in regulating locomotor activity. This structure is deeply embedded in the centre of the brain and has never been studied physiologically because it was always inaccessible to standard, fluorescen...
