In interventional lung cancer diagnosis and treatments  precise segmentation of airway trees from lung CT images provides crucial visualization for preoperative planning and intraoperative guidance to avoid major trachea injury. While 3D region growing can segment main the parts of an airway tree (trachea  left and right main bronchus  as well as bronchi)  the method fails at bronchiole segmentation and is not robust. Mathematical morphology is an anatomical detective. In this paper  we propose a morphological gradient based region growing (MGRG) algorithm to overcome the intensity inhomogeneity  and improve the robustness of 3D region growing on extraction of bronchioles. The MGRG algorithm is validated using lung CT images  and results show that it is able to segment bronchioles  and outperforms the traditional region growing method on airway tree segmentation. 2011 IEEE.   A prospective comparison of molecular assay and touch imprint cytology for intraoperative evaluation of sentinel lymph nodes 期刊论文 中华医学杂志, 2011, 卷号: 124, 期号: 4 作者:  Chen Jiajian;  Yang Benlong;  Chen Jiaying;  Zhang Jiaxin;  Li Dali 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/19 breast carcinoma  sentinel node biopsy  intraoperative diagnosis  touch imprint cytology   Factors associated with the misdiagnosis of sentinel lymph nodes using touch imprint cytology for early stage breast cancer 期刊论文 ONCOLOGY LETTERS, 2011, 卷号: 2, 期号: 2 作者:  Chen, Yi-Zuo;  Zhang, Jia-Xin;  Chen, Jia-Jian;  Liu, Zhe-Bin;  Huang, Xiao-Yan 收藏  |  浏览/下载：5/0  |  提交时间：2019/12/19 breast carcinoma  sentinel node biopsy  intraoperative diagnosis  touch imprint cytology  micrometastasis   A prospective comparison of molecular assay and touch imprint cytology for intraoperative evaluation of sentinel lymph nodes 期刊论文 CHINESE MEDICAL JOURNAL, 2011, 卷号: 124, 期号: 4 作者:  Chen Jia-jian;  Yang Ben-long;  Chen Jia-ying;  Zhang Jia-xin;  Li Da-li 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/19 breast carcinoma  sentinel node biopsy  intraoperative diagnosis  touch imprint cytology   A prospective comparison of molecular assay and touch imprint cytology for intraoperative evaluation of sentinel lymph nodes 期刊论文 CHINESE MEDICAL JOURNAL, 2011, 卷号: 124 - 收藏  |  浏览/下载：7/0  |  提交时间：2020/10/26 ECTOPIC BREAST-TISSUE  AXILLARY DISSECTION  CANCER METASTASIS  FROZEN-SECTION  CARCINOMA  BIOPSY  TRANSPORT  CELLS  breast carcinoma  sentinel node biopsy  intraoperative diagnosis  touch imprint cytology
