碩士 === 國立臺灣大學 === 資訊工程學系 === 86 === In this thesis, a system for 3D reconstruction and visualization of ultrasound images is proposed. The ultrasound technique is frequently used in medical imaging because it is non-invasive, non-radiative, interactive, inexpensive, and suitable for the localization of vessels and tumors in soft tissue. However, the ultrasound images have no space information for registration. In other researches, a mechanical arm or a special rotator is used to register the ultrasound images for 3D reconstruction. This situation is not convenient for physicians because they often operate the transducer of the ultrasound machine in their hands freely. In our research, we develop a 3D ultrasound system with a magnetic space tracker to register the ultrasound images. By attaching the receiver of the space tracker to the transducer, the physician can operate the transducer by his hand while the ultrasound images are registered simultaneously. Some experimental results are also presented in this thesis.
