Abstract

Breast cancer is the number one killer disease among women in Malaysia. In the diagnosis of breast cancer, breast ultrasound examination is commonly used as a supplement to mammography. Ultrasound examination is a non ionizing technique, free of harmful effects. Unfortunately, ultrasound is also known as a time-consuming examination technique with high operator dependency with the results from the examination difficult to discuss, document and reproduce. Three-dimensional imaging provides new information and allows a better interpretation of the standard two-dimensional images. The aim of this study is to therefore develop a PC-based three dimensional ultrasound system to help in the examination and evaluation of breast lesions. The system consists of a PC-based ultrasound system and a magnetic tracking sensor. A sequence of breast ultrasound images were acquired along with the coordinates. These data were then filtered, segmented and finally reconstructed into a 3D image.
