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 ...
