Researchers at Duke University have discovered a way to enhance the effectiveness and safety of sonogenetics or ultrasonic modulation, emerging techniques that use sound waves to control the behavior ...
Validation of Ultrasonic Image Boundary Recognition in Abdominal Aortic Aneurysm
Aortic aneurysm echo ultrasound
2010/1/6
An aneurysm of the abdominal aorta (AAA) is characterized
by modified wall properties, and a balloon-like area usually
filled by a thrombus. A rupture of an aortic aneurysm can
be fatal, yet there ...

Agreement between trained and untrained observers in grading intravascular bubble signals in ultrasonic images
decompression intravascular
2009/6/8
In our experience, it is easier to identify gas bubbles in ultrasonic images than in aural Doppler signals. To verify this, we asked 27 observers with no previous training to estimate the quantity of ...
Effects of Stimulation Side on the Auditory Evoked Magnetic Fields: Objective Assessments of Sound Localization in Bone-conducted Ultrasonic Perception
ultrasound bone-conduction MEG N1m laterality auditory cortex
