Ultrasounds: From Space to Sports
Ultrasound uses sound waves
that bounce off body parts,
producing echoes. A computer
translates the echoes into
images that rival the
quality of CAT scans and
MRIs, showing broken bones,

Sound Detects Breast Cancer
Radiologists suspend a
patient's breast in water,
and then send sound waves
through the water in order
to image breast tissue. The
device uses 256 ultrasonic
sensors to assemble 50 to 70

Ultrasound Stethoscope
A new ultrasound stethoscope
ignores outside noise,
allowing medics to hear
life-saving sounds inside
the body. Developed by
electrical engineers, the
device exploits the Doppler
effect as it sends an

GPS For The Brain
Neurosurgeons' jobs are made
easier by a 3-D CT scan
produced by an advanced
imaging system. It produces
a computerized image of
blood vessels and
surrounding soft tissue,
which can be rotated for

Cardiologists Use Medical Physics to Pinpoint Cause of Chest Pains
Unless a patient with chest pain is checked out right away, it can be difficult to diagnose a heart condition, as opposed to less life-threatening causes such as heartburn. A new stress test can spot ... > more -
Gastroenterologists Use Hi-Res Narrow-Band Imaging to Find Cancer
Gastroenterologists Use Hi-Res Narrow-Band Imaging To Find Cancer New optical technologies are helping gastroenterologists improve cancer detection using colonoscopy. A new endoscope uses HDTV ... > more -
Scientists And Engineers Develop Aerial Imaging System To Identify The Locations Of Persons In Need After Disasters
Research technologists using science and engineering have developed an aerial imaging system for the Center for Disease Control that can help them see how many people need help after a natural ... > more -
Human-Interface Engineers Create Virtual-Reality Experience by Letting Users Walk in Rotating Sphere
A new invention allows users to explore virtual worlds while moving around safely in their real physical environment. Wearing a virtual-reality helmet, users walk inside a rotating, hollow sphere, ... > more -
Neurologists Use New Brain Scanning Device To Better Control Seizures
Doctors are now using a new kind of brain scan called magnetoencephalography (MEG), which measures brain activity in real time. In some cases, MEG can pinpoint the source of an epileptic seizure much ... > more -
Doctors Catch Cancer Earlier with Special MRI
A new kind of MRI machine helps doctors diagnose breast cancer earlier. Patients lie on their stomach and their breasts are placed in two coils, which focus radio waves and allow for more complete ... > more -
Computer Scientists Devise Tool For Visualizing Single Organs
With MRI or CT scans, clinicians have to identify and extract the anatomy out of cross-sections views of the body. Computer scientists have created a new interactive tool that can examine scans and ... > more -
Biomedical Engineers 'Arm' Surgeons For Highly Precise Knee Resurfacing With Robot
Biomedical engineers developed a robotic arm to very precisely resurface the knee before replacing it. In order to do this, a 3-D image of the knee is generated, providing a live-action view of the ... > more -
Radiologists Use Light To Scan The Inner Workings Of The Brain
Radiologists have developed a new device to understand brain activity. It is a collection of fiber optic cables attached to a flexible cap placed atop the head. The cables send near-infrared light ... > more -
Neurologists, Imaging Scientists Use Medical Physics to Spot Disease in Blood Vessels
A new brain-imaging method allows physicians to diagnose Alzheimer's before its onset. A radioactive dye is injected in the blood and travels to the brain, where it attaches to plaque deposits of ... > more
