Biomedical Engineering Unit of Sirindhorn International Institute of Technology presents a database of ultrasound images of breast cancer provided by the Department of Radiology of Thammasat University and Queen Sirikit Center of Breast Cancer of Thailand. The database includes ultrasound, Doppler and elasticity images along with the ground truth hand-drawn by leading radiologists of these centers. The images are free to download and can be used for training and verification of image segmentation algorithms. If you use one or a series of the images, please, site the source as "Rodtook, A., Kirimasthong, K., Lohitvisate, W., Makhanov, S.S. (2018) Automatic initialization of active contours and level set method in ultrasound images of breast abnormalities. Pattern Recognition, Vol 79, pp 172-182".

The project is sponsored by Thailand Research Fund, grants BRG5780012, RSA6280098 and Center of Excellence in Biomedical Engineering of Thammasat University.
