NASA Tech Briefs’ Bio-Medical Web page spotlights bio-medical technologies and product design ideas that have been published in NASA Tech Briefs magazine. This library of tech briefs pertains to the development and rollout of new bio-medical and life sciences technologies produced by NASA, its partners, and industry. Many of the Tech Briefs below are correlated to a Technical Support Package (TSP) or White Paper that can be downloaded free of charge.
Micro-Endoscope as Thin as a Human Hair
Single fiber endoscope
increases resolution
fourfold over previous
similar devices.
Engineers at Stanford University have
developed and demonstrated a prototype
single-fiber endoscope that, they
say, quadruples the resolution over
existing designs, which might lead to
the development of needle-thin, minimally
invasive endoscopes able to view
features out of ...

Hand-Based Biometric Analysis
Hand-based biometric analysis systems and techniques provide robust handbased
identification and verification. An
image of a hand is obtained, which is
then segmented into a palm region and
separate finger regions. Acquisition of
the image is performed without requiring
particular orientation or placement
restrictions. Segmentation is performed
without the use ...

Choosing Chiller Pumps to Cool Medical Lasers
Medical lasers must be
cooled either by premounted
or portable
chiller systems.
Laser systems continue to grow in
application use throughout the medical
industry. Applications for laser systems
include diagnostic analysis systems, DNA
sequencing systems, dental cleaning and
surgery, skin care, eye surgery, tattoo
removal, and much more. ...

Functional Near-Infrared Spectroscopy Signals Measure Neuronal Activity in the Cortex
This non-invasive monitoring method can be used to evaluate the mental state of people
performing critical tasks.
Functional near infrared spectroscopy
(fNIRS) is an emerging optical
neuroimaging technology that indirectly
measures neuronal activity in the cortex
via neurovascular coupling. It quantifies
hemoglobin concentration
([Hb]) and thus measures the ...

New Material Enables Improved Ultrasound
Ultrasound technology could soon be
improved to produce high-quality, highresolution
images, thanks to the development
of a new key material by a team
of researchers in the Department of
Biomedical Engineering at Texas A&M
University, College Station.
