Breast ultrasound is an important complement to mammography that allows differentiating between benign and malignant lesions. The early diagnosis and specialized care for women with breast cancer are indispensable for a better therapeutic result and prognosis of cases. Thereby, it is necessary training professionals to emit trustworthy diagnoses. Here, we set up lesions-like structures in a plasticized...
This paper describes the procedure to make a realistic and novel breast and breast cancer phantoms in order to mimic acoustic and geometric properties of the woman breast. Comparing the propagation speed of sound in our phantoms with others papers, we achieved 96.34 % of similarity in breast phantoms and 96.99 % of similarity in breast cancer phantoms by using accessible and cheap materials; furthermore,...
Simulation experiment of breast cancer detection has been performed using an ultrashort-pulse radar with compact vivaldi antennas. A synthetic breast phantom and metallic balls or high-k dielectric cubes are used as tumor in our experiment. Image reconstructions of the breast models using reflection data will be presented. We measure reflection data in order to reconstruct images of the breast models...
This contribution presents a selection of phantom and clinical results from a prototype multistatic imaging radar designed and built at Bristol. Complex phantoms are employed in order to approximate the difficulty in imaging breast tissue, however, even so, imaging in a clinical environment poses particular challenges.
Microwave imaging has grown in recent years as a promising technique for breast cancer detection. Its physical principle exploits the different dielectric characteristics of normal and tumoral breast tissues. In 2007 a study evaluated the dielectric properties of normal (adipose, glandular and fibroconnective), malignant (invasive and non-invasive ductal and lobular carcinomas) and benign (fibroadenomas...
