BACKGROUND & OBJECTIVES Biopsy of palpable breast masses can be performed manually by palpation guidance or under imaging guidance. Based on retrospective studies, image guided biopsy is considered more accurate than palpation guided breast biopsy; however, these techniques have not been compared prospectively. We conducted this prospective study to verify the superiority and determine the size...

BACKGROUND The purpose of this study was to determine the feasibility of nondaily image-guided radiotherapy (RT) strategies with intensity-modulated radiotherapy (IMRT) for head and neck cancer. METHODS Alignment data was analyzed from 103 consecutive patients treated by IMRT for head and neck cancer who had undergone daily imaging with onboard mega-voltage CT (MVCT), resulting in 3275 images...

Image matting is an important computer vision problem. Many existing methods leverage a hand-made trimap to provide auxiliary information, which expensive and time-consuming for real-world applications. In recent years, some trimap-free have been proposed, completely get rid of any user input. However, their performance lag far behind trimap-based due the ambiguity This paper proposes method th...
