Abstract
In this paper, an algorithm is introduced for making breast phantoms and abnormal masses (cyst, fibroadenoma and cancer). The evaluation of ultrasonic properties (sound velocity and amplitude attenuation coefficient) of these normal breast phantoms and abnormal masses and their ultrasonic images shows that they are stable over 3 years. The measurement and evaluation results of ultrasonic images of our phantoms show that they behave like human breast tissues. Practicing with these phantoms for developing fine-needle aspiration (FNA) skills in sonographers shows that these phantoms reduce the time required for successful FNA. The ultrasonic phantoms have different ultrasonic applications, including ultrasonic medical imaging, the quality control of ultrasound (US) instruments, processing technique evaluation and US training; moreover, they are stable in room temperature and can keep their specifications for more than 3 years.
