Research And Application Of 3D Ultrasonic Imaging Technology

The 3D image information and its inner spatial structure are displayed by the 3D ultrasound imaging technology. Some shortages of plane ultrasound imaging technology are also made up. As one of quickly developed medical image subject, the 3D ultrasound imaging technology has already been applied in many fields of medicine, and can make some medical checks and diagnoses towards heart, cholecyst, kidney, blood vessel, skeleton and fetus, etc.The 3D ultrasound imaging technologies are deeply researched and discusses in this paper, and the following three main facts are included:1: The local feature structure segmentation technique is improved. The method combining the boundary model with the local character is presented, which can semi-automatically process image segmentation problem, and realize the segmentation of coronary artery.2: In the Freehand 3D ultrasound imaging system, the ultrasound 3D rebuilding method of anomalistic sampling plane is used to realize the 3D ultrasound imaging rebuilding of clay left neck artery.3: The calculation of footprint table in volume rendering algorithm is simplified and enhanced. The 3D ultrasound imaging rebuilding of cholecyst, heart, embryo and fetus are realized.
