Abstract

Ultrasound scanning system is a non ionizing technique for breast mammography. Unfortunately, ultrasound has not approved by FDA as a screening tool yet due to the lack of spatial resolution and high operator dependent. Therefore, the quality of imaging depends on the operator technique and experience. The purpose of this project is to develop an automated 2D motion system for ultrasound scanning designed for breast cancer patient. The scanning was performed by automated movement of a transducer during image acquisition. Therefore, the automated motion system needs a very high precision of position control system which integrated with a microcontroller and two appropriate distance sensors on each axis. Besides, graphical user interface has been designed to interface between the microcontroller and personal computer. The control method for the automated motion system can achieve a resolution of 2mm. This is used to replace the conventional handholding ultrasound probe and to increase the spatial resolution of ultrasound.
